EIAT - Elevator Industry Aptitude Test — Questions and Answers

Question 1: A hoist drum makes 5.5 revolutions per rope pull. If the drum diameter is 24 inches, how many feet of rope is wound per pull?

34.56 ft (Correct answer)
27.5 ft
103.67 ft
69.12 ft

Correct answer: 34.56 ft

Circumference = π × 24 ≈ 75.36 in; 5.5 × 75.36 = 414.5 in ÷ 12 = 34.56 ft.

Question 2: The hydraulic reservoir for an elevator holds 15 gallons. A technician needs to perform a fluid change, and the replacement hydraulic oil is sold in 5-liter containers. How many 5-liter containers are needed to completely fill the reservoir? (1 gallon ≈ 3.785 liters)

12 (Correct answer)
11
15
10

Correct answer: 12

First, convert the total capacity from gallons to liters: 15 gallons * 3.785 L/gallon = 56.775 liters. Next, determine how many 5-liter containers are required to meet this volume: 56.775 L / 5 L/container = 11.355 containers. Since you cannot purchase a fraction of a container, you must purchase 12 containers to have enough fluid.

Question 3: Which value of m satisfies 3m + 2 = 2m + 9?

7 (Correct answer)
5
11
3

Correct answer: 7

Subtracting 2m from both sides: m + 2 = 9, so m = 7.

Question 4: Which tool is used to bend rigid electrical conduit to a precise angle during elevator wiring?

Pipe wrench
Conduit bender (Correct answer)
Hammer and mandrel
Hacksaw

Correct answer: Conduit bender

A conduit bender allows electricians to form accurate bends in rigid conduit without kinking the pipe.

Question 5: Which sentence contains a run-on error?

The technician filed the report and left the site.
The motor overheated, so the system shut down.
The elevator was repaired; it passed inspection.
The alarm sounded the operator evacuated the passengers immediately. (Correct answer)

Correct answer: The alarm sounded the operator evacuated the passengers immediately.

45% of 60 = 27 installations; 27 ÷ 3 per week = 9 weeks.

Question 7: What is the result of 7/4 divided by 0.25?

3.5
7 (Correct answer)
1.75
5

Correct answer: 7

First, convert both numbers to the same format, either fractions or decimals. As a decimal, 7/4 is 1.75. So, 1.75 / 0.25 = 7. Alternatively, as fractions, 0.25 is 1/4. The problem becomes 7/4 divided by 1/4. To divide by a fraction, you multiply by its reciprocal: 7/4 * 4/1 = 28/4 = 7.

Question 8: Which tool is best suited for pulling wire through conduit during elevator electrical installation?

Fish tape (snake) (Correct answer)
Conduit bender
Needle-nose pliers

Correct answer: A 6-in-1 or 11-in-1 screwdriver

A 6-in-1 or 11-in-1 screwdriver is a specific type of hand tool designed for efficiency by housing multiple interchangeable bits (like Phillips and flathead) and nut driver sizes within its shaft and handle.

Question 11: What is 'backlash' in a gear system?

Gear tooth breakage under load
The small gap between meshing gear teeth (Correct answer)
Reverse rotation of the drive shaft
Vibration caused by unbalanced gears

Correct answer: The small gap between meshing gear teeth

Backlash is the slight clearance between mating gear teeth, necessary for lubrication and thermal expansion but too much causes imprecision.

Question 12: A technician is installing a new traveling cable that weighs 2.5 pounds per foot. The total length of the cable needed is 'L' feet. The total weight of the cable must not exceed 180 pounds. Which of the following inequalities correctly represents the maximum length of the cable that can be used?

2.5 * L <= 180 (Correct answer)
L / 2.5 <= 180
2.5 * L > 180
2.5 * L >= 180

Correct answer: 2.5 * L <= 180

Let 'L' be the length of the cable in feet. The total weight is the weight per foot (2.5 lbs) multiplied by the length (L). The problem states the total weight must not exceed 180 pounds, which means it must be less than or equal to 180. Therefore, the correct inequality is 2.5 * L <= 180.

Question 13: Solve for x: 2(x - 5) + 3x = 15

7
4
5 (Correct answer)
6

Correct answer: 5

Expanding: 2x - 10 + 3x = 15 → 5x = 25 → x = 5.

Question 19: A technician is writing a log entry. Which of the following sentences is grammatically correct and most clearly written?

After replacing the worn hoist rope, the elevator's performance improved immediately.
Because the hoist rope was worn, the technician replaced it, and performance improved. (Correct answer)
Replacing the hoist rope, the elevator's performance improving as a result.
The technician replaced the worn hoist rope, the elevator's performance improved immediately.

Correct answer: Because the hoist rope was worn, the technician replaced it, and performance improved.

This sentence is the most clear and grammatically sound. It correctly establishes a cause-and-effect relationship using 'Because', and it properly joins two independent clauses ('the technician replaced it' and 'performance improved') with a comma and the coordinating conjunction 'and'. Option A is a comma splice. Option B correctly uses an introductory phrase but is less descriptive. Option C is a sentence fragment.

Question 20: A regulation states: 'Elevator doors shall not open unless the car is within the landing zone.' Which situation violates this rule?

Doors remain closed while the car travels between floors.
Doors open when the car is 18 inches below the floor level. (Correct answer)
Doors open when the car is 3 inches above the floor level within the allowable zone.
Doors open when the car stops exactly at the floor level.

Correct answer: Doors open when the car is 18 inches below the floor level.

If the car is 18 inches below the landing zone and the doors open, this violates the requirement to stay within the landing zone.

Question 21: What is the best definition of the word 'protocol' in an emergency response protocol?

A set of established rules and procedures (Correct answer)
A government agency
A legal document
A training certificate

Correct answer: A set of established rules and procedures

Correct answer: Hearing protection

The bulletin lists hard hats, safety glasses, and steel-toed boots; hearing protection is not mentioned.

Question 24: Identify the correct use of 'its' vs. 'it's' in the following sentence: '_ important to check _ oil level daily.'

Its / it's
Its / its
It's / its (Correct answer)
It's / it's

Correct answer: It's / its

'It's' means 'it is' (contraction) and 'its' shows possession; the first blank needs the contraction and the second needs possession.

Question 25: What is the primary function of an inductor in an electrical circuit?

Convert AC to DC
Store energy in an electric field
Amplify voltage signals
Store energy in a magnetic field and oppose changes in current (Correct answer)

Correct answer: Store energy in a magnetic field and oppose changes in current

Question 26: A maintenance manual states that a component is "obsolete." What does this mean?

Recently upgraded to a newer model
Highly specialized and difficult to find
Extremely dangerous and must be replaced
No longer in use or current production (Correct answer)

Correct answer: No longer in use or current production

"Obsolete" means outdated and no longer produced or used. Something obsolete has been replaced by newer technology or methods. It describes the age/currency status, not the danger level.

Question 27: Which class of lever is demonstrated when a person uses a crowbar with the fulcrum between the effort and the load?

Class 2
Class 4
Class 3
Class 1 (Correct answer)

Correct answer: Class 1

A Class 1 lever has the fulcrum positioned between the effort force and the load, like a seesaw or crowbar in typical use.

Question 28: In a simple pulley system with a fixed pulley and a movable pulley, the mechanical advantage is:

3
2 (Correct answer)
4
1

Correct answer: 2

A system with one fixed and one movable pulley provides a mechanical advantage of 2, meaning half the effort is needed to lift the load.

Question 29: Choose the sentence that demonstrates correct subject-verb agreement.

Neither the head technician nor the apprentices is available right now.
The box of replacement relays are on the workbench.
Each of the elevator cars were inspected for safety.
The main control panel, along with its diagnostic cables, needs to be updated. (Correct answer)

Correct answer: The main control panel, along with its diagnostic cables, needs to be updated.

The subject of the sentence is 'The main control panel', which is singular. The phrase 'along with its diagnostic cables' is an intervening phrase and does not change the subject's number. Therefore, the singular verb 'needs' is correct. In option A, the subject is 'box' (singular), so the verb should be 'is'. In option B, the subject 'Each' is singular, so the verb should be 'was'. In option C, when using 'neither/nor', the verb agrees with the subject closest to it ('apprentices'), so the plural verb 'are' should be used.

Question 30: A wire rope makes two full wraps around a sheave. How many degrees of total rotation does this represent?

720 degrees (Correct answer)
360 degrees
180 degrees
540 degrees

Correct answer: 720 degrees

One full wrap equals 360 degrees, so two full wraps equal 720 degrees.

Question 31: Which of the following sentences contains a punctuation error?

The controller, which was recently upgraded, is working perfectly.
Please check the guide rails the door mechanism and the traveling cable. (Correct answer)
The technician needed three tools: a wrench, a voltmeter, and a screwdriver.
Although the motor was noisy, it was still functioning within specifications.

Correct answer: Please check the guide rails the door mechanism and the traveling cable.

This sentence is missing commas to separate the items in a series. The correct punctuation would be: 'Please check the guide rails, the door mechanism, and the traveling cable.' This is known as using the serial or Oxford comma. Option A correctly uses a colon to introduce a list. Option B correctly uses a comma after an introductory dependent clause. Option C correctly uses commas to set off a non-essential clause.

Question 32: Choose the sentence with the correct pronoun case.

Him and the crew finished the job early.
Between you and I, the cable looked worn.
The supervisor gave the schedule to her and me. (Correct answer)
The safety briefing was given to he and the new apprentice.

Correct answer: The supervisor gave the schedule to her and me.

'Her' and 'me' are object pronouns, correct after the preposition 'to.'

Question 33: CAKE is to BAKER as BACON is to _______.

Butcher (Correct answer)
Farmer
Winemaker
Cobbler
Caretaker

Correct answer: Butcher

Explanation: In this analogy, we're looking for a word that represents the person who typically produces or prepares bacon, just as a baker produces cakes. Among the options provided, the correct answer is: Butcher A butcher is a person who typically prepares and sells meat products, including bacon, similar to how a baker prepares and sells cakes.

Question 34: What comes next: 1, 4, 9, 16, 25, ___?

36 (Correct answer)
30
34
49

Correct answer: 36

These are perfect squares (1², 2², 3², 4², 5²), so the next is 6² = 36.

Question 35: Choose the sentence with correct subject-verb agreement.

Neither the motor nor the cables were functioning properly. (Correct answer)
The team of mechanics was needing more supplies.
Each of the elevator components need to be inspected.
The set of instructions are on the workbench.

Correct answer: Neither the motor nor the cables were functioning properly.

With 'neither...nor,' the verb agrees with the subject closest to it; 'cables' is plural so 'were' is correct.

Question 36: A square piece of paper is folded in half diagonally, and one hole is punched near the center of the folded edge. How many holes appear when the paper is fully unfolded?

3
4
2 (Correct answer)
1

Correct answer: 2

A diagonal fold creates one layer of symmetry, so punching one hole through both layers produces two holes when unfolded.

Question 37: In a traction elevator, rope grip is maintained by:

Friction between the rope and sheave grooves (Correct answer)
Mechanical locking pins through each rope
Magnetic clamping of the sheave
Hydraulic pressure applied to rope clamps

Correct answer: Friction between the rope and sheave grooves

Traction drive relies on friction in the grooved sheave — rope tension and groove geometry (undercut or round) generate the tractive force.

Question 38: A city requires elevators to pass inspection 90% of the time on the first attempt. Out of 150 inspections, how many are allowed to fail initially?

10
18
12
15 (Correct answer)

Correct answer: 15

10% may fail; 10% of 150 = 15 elevators.

Question 39: What happens to current in a series circuit if one component fails (opens)?

Current flow stops completely (Correct answer)
Current reverses direction
Current continues through the remaining components
Current increases in the remaining components

Correct answer: Current flow stops completely

In a series circuit, all components share the same single path, so an open in any component stops all current flow.

Question 40: A hoisting system has a mechanical advantage ratio of 3:1. If a worker applies 90 pounds of force, what maximum load can be lifted?

270 pounds (Correct answer)
93 pounds
30 pounds
180 pounds

Correct answer: 270 pounds

A 3:1 mechanical advantage means the output force is 3 times the input force. 90 × 3 = 270 pounds. This ratio tells you how many times the system multiplies your effort.

Question 41: Which condition must be true for an object to be in rotational equilibrium?

Both net force and net torque = 0 (Correct answer)
Net force = 0 only
Angular velocity = 0
Net torque = 0 only

Question 43: Which tool is used to test whether an elevator safety circuit is open or closed during troubleshooting?

Voltage tester only
Phase meter
Insulation tester
Continuity tester or multimeter in continuity mode (Correct answer)

Correct answer: Continuity tester or multimeter in continuity mode

A continuity tester or multimeter in continuity/beep mode confirms whether a safety circuit is electrically complete.

Question 44: A passage states: 'Counterweights offset the weight of the car and a portion of its rated load, reducing the energy needed to raise and lower the car.' What is the main purpose of a counterweight?

To improve passenger comfort
To prevent the car from exceeding its rated load
To reduce energy consumption by offsetting car weight (Correct answer)
To increase the elevator's speed

Correct answer: To reduce energy consumption by offsetting car weight

The passage directly states that counterweights reduce the energy needed to move the car by offsetting its weight and a portion of the load.

Question 45: A technician's report says: 'The governor rope exhibited fraying at intermittent intervals along its length.' What does this mean?

The rope was completely worn through.
The rope was frayed only in one specific spot.
The rope had fraying appearing at scattered points throughout its length. (Correct answer)
The rope was frayed only at the ends.

Correct answer: The rope had fraying appearing at scattered points throughout its length.

'Intermittent intervals' means occurring at irregular, scattered points, not continuously or only at one location.

Question 46: A procedure manual reads: 'Obtain written authorization before commencing any non-routine maintenance.' A technician wants to replace a worn cable. Should they obtain written authorization first?

Yes, cable replacement is non-routine and requires written authorization. (Correct answer)
Only if the cable has already snapped.
Only if the supervisor is on-site.
No, cable replacement is routine work.

Correct answer: Yes, cable replacement is non-routine and requires written authorization.

Cable replacement is not routine maintenance, so written authorization must be obtained before starting the work.

Question 47: A technician needs to verify that a newly installed guide rail is perfectly vertical. Which of the following tools is the most appropriate for this task?

A tape measure
A caliper
A framing square
A spirit level (Correct answer)

Correct answer: A spirit level

A spirit level is specifically designed to indicate whether a surface is perfectly horizontal (level) or vertical (plumb). While a framing square can check for 90-degree angles, it doesn't verify verticality over a distance as effectively as a level.

Question 48: Select the correctly punctuated sentence.

We need the following tools, oil, and, new cables.
We need the following: tools, oil, and new cables. (Correct answer)
We need the following tools oil, and new cables.
We need: the following tools oil and new cables.

Correct answer: We need the following: tools, oil, and new cables.

2 ft × 3 ft
4 ft × 8 ft
8 ft × 12 ft (Correct answer)
6 ft × 8 ft

Correct answer: 8 ft × 12 ft

Multiply each blueprint dimension by 4: 2 × 4 = 8 ft and 3 × 4 = 12 ft.

Question 53: A safety notice reads: 'Do not enter the pit unless the pit stop switch is in the OFF position and the car is locked out.' Which conditions must be met before entering the pit?

Only the pit stop switch must be OFF
Both the pit stop switch must be OFF and the car must be locked out (Correct answer)
A supervisor must be present
Only the car must be locked out

Correct answer: Both the pit stop switch must be OFF and the car must be locked out

The notice uses 'and' to join two conditions, meaning both the pit stop switch must be OFF and the car must be locked out.

Question 54: An inspection report notes: 'Observed excessive wear on guide shoe inserts; replace before next scheduled service.' When should the inserts be replaced?

Only when the elevator fails inspection
At the next scheduled service
Before the next scheduled service (Correct answer)

Question 60: Most parents thought it was an __________ decision to make the field trip part of the yearly routine, as they valued the trip as exciting and empowering for the children.

ill-advised
obscure
economical
adequate (Correct answer)
remarkable

Correct answer: adequate

Explanation: The correct answer is adequate, which means satisfactory or acceptable. Since according to the second part of the sentence the parents demonstrated positive appreciation of the trip’s contribution to their children, we expect a positive adjective to describe the decision to make the field trip part of the yearly routine. Only two words answer this notion. ‘Remarkable’ might have been the best choice, as it has a very positive tone, comparable to the positive appreciation of the trip as “empowering” and “exciting”. Nonetheless, the word ‘remarkable’ cannot be placed after the determiner “an”, thus ‘adequate’ is the next best choice to complete the sentence and the correct answer.

Question 61: Which sentence correctly uses a semicolon?

The inspection passed; the elevator returned to service the next day. (Correct answer)
The maintenance log was updated; and filed with the supervisor.
The elevator was out of service; because the cable snapped.
She ordered the parts; but they arrived late.

Correct answer: The inspection passed; the elevator returned to service the next day.

A semicolon correctly joins two independent clauses without a coordinating conjunction.

Question 62: Which of the following best describes the function of a brake on a gearless traction elevator?

Reduce electrical current during startup
Hold the car stationary when the motor is de-energized (Correct answer)
Slow the motor between floors
Limit door closing speed

Correct answer: Hold the car stationary when the motor is de-energized

The electromagnetic brake engages when power is removed from the motor to hold the car and prevent drift at a landing.

Question 63: A counterweight assembly is shown in a hoistway cross-section. If the car is positioned on the left side of the hoistway, where is the counterweight typically located?

On the same side as the car
Directly below the car
On the right side or rear of the hoistway (Correct answer)
Directly above the car

Correct answer: On the right side or rear of the hoistway

The counterweight travels in a separate guide rail path offset from the car, typically on the opposite or rear side of the hoistway.

Question 64: An elevator technician needs to pry open a stuck panel using a crowbar. To achieve the maximum prying force with the least effort, where should the fulcrum be placed?

The fulcrum position does not affect the force
As close as possible to the hand applying the effort
Exactly in the middle of the crowbar
As close as possible to the panel being pried (Correct answer)

Correct answer: As close as possible to the panel being pried

A crowbar is a Class 1 lever, where the fulcrum is between the effort and the load. To maximize the mechanical advantage (output force), the effort arm (distance from fulcrum to effort) should be as long as possible, and the load arm (distance from fulcrum to load) should be as short as possible. Placing the fulcrum very close to the panel (the load) accomplishes this, multiplying the technician's effort into a much larger prying force.

Question 65: Which sentence uses the word 'redundant' correctly in an elevator safety context?

The redundant mechanic refused to work overtime.
The redundant cable replaced the broken one.
Installing a redundant elevator made the old one faster.
The system uses redundant safety devices so one failure won't cause an accident. (Correct answer)

Correct answer: The system uses redundant safety devices so one failure won't cause an accident.

'Redundant' in engineering means having backup systems so a single failure does not cause a critical problem.

Question 66: A maintenance schedule lists service every: 30, 60, 90, 120, ___ days. What comes next?

160
150 (Correct answer)
155
140

Correct answer: 150

The series increases by 30 each time, so 120 + 30 = 150.

Question 67: The boy was filled with _______ when he saw that his sister broke his favorite toy.

Confusion
Doubt
Joy
Wrath (Correct answer)
Ambition

Correct answer: Wrath

Explanation: According to the sentence, the boy’s sister broke his favorite toy. We can therefore assume that the boy was filled with a negative emotion. Wrath is a negative emotion, and it fits the context of the sentence. In case we do not know the word wrath, we can eliminate joy and ambition, which are both positive words. Confusion is not necessarily a negative emotion and does not fit the sentence as much as wrath. Doubt means uncertainty, which can also be marked as incorrect.

Question 68: A building has 5 elevators. During peak hours, 3 of them handle 72% of all trips. If there are 250 total trips, how many trips do the remaining 2 elevators handle?

70 trips (Correct answer)
80 trips
75 trips
60 trips

Correct answer: 70 trips

72% of 250 = 180 trips for 3 elevators; 250 − 180 = 70 trips for the other 2.

Question 69: A wiring conduit must span 7 yards. How many feet of conduit is needed?

21 ft (Correct answer)
24 ft
14 ft
18 ft

Correct answer: 21 ft

7 yards × 3 ft/yard = 21 feet.

Question 70: What comes next: 1, 2, 4, 7, 11, ___?

16 (Correct answer)
14
15
17

Correct answer: 16

The differences increase by 1 each step (1, 2, 3, 4, 5), so 11 + 5 = 16.

Question 71: A passage from a technical specification states: 'All wiring shall be run in conduit, except low-voltage signal wiring, which may be run in cable trays or raceways.' A 24V control signal wire would most appropriately be installed in:

A cable tray or raceway (Correct answer)
Underground duct banks
Open air without any enclosure
Rigid metal conduit only

Correct answer: A cable tray or raceway

At 24V, the wire qualifies as low-voltage signal wiring, which the specification explicitly permits to be run in cable trays or raceways.

Question 72: A spring under a 300 lb load compresses 2 inches. What is the spring constant (k)?

600 lb/in
60 lb/in
3 lb/in
150 lb/in (Correct answer)

Correct answer: 150 lb/in

Spring constant k = F / x = 300 lb ÷ 2 in = 150 lb/in.

Question 73: A technical memo states that a relay 'de-energizes' when the safety circuit opens. De-energizing a relay coil means:

Current to the coil is interrupted, releasing the magnetic field (Correct answer)
The relay contacts are welded in the closed position
Electrical current continues flowing through the coil
Voltage to the relay increases above rated value

Correct answer: Current to the coil is interrupted, releasing the magnetic field

De-energizing a relay coil means current stops flowing through it, collapsing the magnetic field and allowing contacts to return to their normal position.

Question 74: Solve for x: x/6 + 4 = 9

42
54
30 (Correct answer)
18

Correct answer: 30

Subtracting 4 from both sides gives x/6 = 5, so x = 30.

Question 75: A bolt requires 7/8 inch clearance. A gap measures 3/4 inch. By how much is the gap short?

1/16 inch
1/8 inch (Correct answer)
3/8 inch
1/4 inch

Correct answer: 1/8 inch

7/8 − 3/4 = 7/8 − 6/8 = 1/8 inch short.

Question 76: What is the next number in the series: 3, 9, 27, 81, ___?

216
243 (Correct answer)
189
162

Correct answer: 243

Each term is multiplied by 3, so 81 × 3 = 243.

Question 77: A work order states: 'Replace the hoist rope on Unit #4 before the scheduled inspection on Friday.' What is the primary task?

Review Unit #4's maintenance history
Replace the hoist rope on Unit #4 (Correct answer)
Schedule the Friday inspection
Contact the inspection team

Correct answer: Replace the hoist rope on Unit #4

The instruction's action verb is 'replace' and its direct object is 'the hoist rope on Unit #4,' making that the primary task.

Question 78: A third-class lever has the effort applied between the fulcrum and the load. This arrangement always:

Reduces the load on the fulcrum
Creates a mechanical advantage greater than 1
Multiplies distance/speed of movement (Correct answer)
Multiplies force

Correct answer: Multiplies distance/speed of movement

Third-class levers sacrifice force (MA < 1) but amplify the distance and speed of the load's movement.

Question 79: A 2:1 roping arrangement in a traction elevator means:

Two separate motors are used to raise the cab
The hoisting ropes support twice the rated load
The motor shaft turns twice for every foot the cab moves
The cab moves at half the speed of the rope (Correct answer)

Correct answer: The cab moves at half the speed of the rope

In 2:1 roping, the rope travels twice the distance the cab moves, so cab speed is half the rope speed but the tension in the ropes is halved.

Question 80: An elevator weighs 4,500 kilograms. Approximately how many pounds is that? (1 kg ≈ 2.205 lbs)

7,900 lbs
10,500 lbs
9,920 lbs (Correct answer)
11,025 lbs

Correct answer: 9,920 lbs

4,500 kg × 2.205 lbs/kg ≈ 9,922.5 lbs, closest to 9,920 lbs.

Question 81: Simplify: 4(2y + 3) - 2y

8y + 12
6y + 12 (Correct answer)
10y + 12
6y + 3

Correct answer: 6y + 12

Expanding gives 8y + 12 - 2y = 6y + 12.

Question 82: Which sentence uses the words 'its' and 'it's' correctly?

Its time to check the elevator and it's emergency brake.
It's time to check the elevator and it's emergency brake.
It's time to check the elevator and its emergency brake. (Correct answer)
Its time to check the elevator and its emergency brake.

Correct answer: It's time to check the elevator and its emergency brake.

'It's' is a contraction for 'it is'. 'Its' is a possessive pronoun that means 'belonging to it'. The sentence should read: 'It is time to check the elevator and the emergency brake belonging to it.' Therefore, 'It's time... and its emergency brake' is the correct construction.

Question 83: When a small gear drives a large gear, the output shaft produces:

Lower speed and higher torque (Correct answer)
Higher speed and lower torque
Same speed and same torque
Higher speed and higher torque

Correct answer: Lower speed and higher torque

Driving a larger gear results in a speed decrease and a proportional torque increase at the output shaft.

Question 84: Which of the following is a compound sentence?

After the inspection, the elevator was repaired.
The elevator failed the inspection, and it was taken out of service. (Correct answer)
Because the elevator failed, repairs were ordered.
The elevator failed the inspection.

Correct answer: The elevator failed the inspection, and it was taken out of service.

A compound sentence joins two independent clauses with a coordinating conjunction like 'and.'

Question 85: A wire is cut into two pieces. One piece is 4 times longer than the other. The total length is 60 m. How long is the shorter piece?

20 m
12 m (Correct answer)
15 m
10 m

Correct answer: 12 m

Let shorter = x; x + 4x = 60 → 5x = 60 → x = 12 m.

Question 86: What are the direction and the velocity of rotation (angular velocity) of Gear 3 compared to Gear 1?

Both gears revolve at the same angular velocity and in the same direction
Gear 3 rotates slower than Gear 1 and both rotate in the same direction (Correct answer)
Gear 3 rotates faster and in the opposite direction to Gear 1

Correct answer: Gear 3 rotates slower than Gear 1 and both rotate in the same direction

Explanation: The correct answer is Gear 3 rotates slower than Gear 1 and both rotate in the same direction.

Question 87: Select the sentence that correctly uses a subordinate clause.

Although the motor was old.
Because the alarm triggered.
Since the report was filed.
When the inspector arrived, the crew was already working. (Correct answer)

Correct answer: When the inspector arrived, the crew was already working.

A subordinate clause must be attached to an independent clause; option B completes the thought.

Question 88: Which sentence uses 'fewer' and 'less' correctly?

We have fewer time to complete the inspection.
There is fewer oil in the reservoir than expected.
There are less technicians on duty today.
Fewer complaints were filed after the upgrade. (Correct answer)

Correct answer: Fewer complaints were filed after the upgrade.

'Fewer' applies to countable nouns like 'complaints,' while 'less' applies to uncountable quantities.

Question 89: A 900 kg elevator car accelerates downward at 1.5 m/s². What is the net force acting on it? (g = 9.8 m/s²)

900 N downward
8,820 N downward
7,470 N downward
1,350 N downward (Correct answer)

Correct answer: 1,350 N downward

Net force = mass × acceleration = 900 × 1.5 = 1,350 N downward.

Question 90: After a 20% reduction in staff due to a slowdown, an elevator service branch now has 48 technicians. How many technicians did the branch have before the reduction?

38
72
58
60 (Correct answer)

Correct answer: 60

If there was a 20% reduction, the remaining 48 technicians represent 80% (100% - 20%) of the original staff. Let the original number be 'x'. The equation is 0.80 * x = 48. To find x, divide 48 by 0.80, which equals 60.

Question 91: A maintenance schedule requires that for every 3 elevators inspected (E), a technician must complete 5 pages of paperwork (P). Which equation correctly describes the relationship between elevators inspected and pages of paperwork?

P = 3/5 E
3E = 5P
5E = 3P (Correct answer)
E = 3/5 P

Correct answer: 5E = 3P

The ratio of elevators to paperwork is 3 to 5 (E/P = 3/5). To express this as an equation without fractions, we can cross-multiply. This gives us 5 * E = 3 * P, or 5E = 3P. This equation maintains the correct ratio; for example, if E=3, then 5(3) = 15, so 3P = 15 and P = 5, which matches the initial condition.

Question 92: What is the function of the underlined word in: 'The technician, exhausted from the long shift, completed the report.'?

Appositive phrase
Predicate adjective
Participial phrase acting as an adjective (Correct answer)
Subject

Correct answer: Participial phrase acting as an adjective

'Exhausted from the long shift' is a participial phrase that modifies 'the technician.'

Question 93: Identify the sentence with a correctly placed apostrophe.

The elevator's emergency brake activated instantly. (Correct answer)
The elevators' emergency brake activated instantly.
The elevators emergency brake activated instantly.
The elevator's emergency brakes' activated instantly.

Correct answer: The elevator's emergency brake activated instantly.

The apostrophe in 'elevator's' correctly shows singular possession of the emergency brake.

Question 94: Which cross-section shape would result from cutting a cylinder horizontally (perpendicular to its axis)?

Rectangle
Oval
Ellipse
Circle (Correct answer)

Correct answer: Circle

A horizontal cut perpendicular to a cylinder's vertical axis produces a perfect circle.

Question 95: If 2a + b = 14 and b = 4, what is a?

4
5 (Correct answer)
7
6

Correct answer: 5

Substituting b = 4: 2a + 4 = 14 → 2a = 10 → a = 5.

Question 96: Which cyclist has to pedal harder in order to go up the ramp?

The same
B (Correct answer)
A

Correct answer: B

Explanation: In this question, we are asked which rider would need to pedal harder in order to climb the ramp. We can see that though the ramps are of different lengths, the height of the logs in both cases is the same. For this reason, we should understand that the shorter ramp will be steeper. As is known from daily life, it is harder to pedal up a steeper incline. Since in Figure B, the length is shorter and the incline is greater, it would be harder to pedal up the ramp.

Question 97: If a lever has a mechanical advantage of 4 and the effort force is 50 lb, the load it can lift is:

400 lb
200 lb (Correct answer)
50 lb
12.5 lb

Correct answer: 200 lb

Mechanical advantage = Load / Effort, so Load = MA × Effort = 4 × 50 = 200 lb.

Question 98: A code section states: 'Inspection certificates shall be conspicuously posted within the elevator car.' Where must the certificate be placed?

In a clearly visible location inside the car (Correct answer)
In the elevator machine room
In the building manager's office
Behind the control panel

Correct answer: In a clearly visible location inside the car

'Conspicuously posted' means displayed in a clearly visible location, which must be inside the elevator car.

Question 99: Select the sentence written in parallel structure.

The job requires reading blueprints, wire soldering, and to drill holes.
The job requires to read blueprints, soldering wires, and drill holes.
The job requires reading blueprints, soldering wires, and drilling holes. (Correct answer)
The job requires reading blueprints, to solder wires, and drilling holes.

Correct answer: The job requires reading blueprints, soldering wires, and drilling holes.

Parallel structure requires all items in a list to use the same grammatical form; here, all use gerunds (-ing).

Question 100: An elevator modernization project was budgeted at $85,000 but came in 12% over budget. What was the actual cost?

$95,000
$93,200
$97,200
$95,200 (Correct answer)

Correct answer: $95,200

$85,000 × 1.12 = $95,200.
