EIAT - Elevator Industry Aptitude Test — Questions and Answers

Question 1: Find the missing number: 100, 91, 83, 76, 70, ___?

64
66
63
65 (Correct answer)

Correct answer: 65

The differences are −9, −8, −7, −6, −5, so 70 − 5 = 65.

Question 2: A drive gear turns at 180 RPM and is connected to a driven gear with a gear ratio of 6:1. What is the speed of the driven gear?

30 RPM (Correct answer)
1,080 RPM
174 RPM
186 RPM

Correct answer: 30 RPM

A gear ratio of 6:1 means the driving gear turns 6 times for every 1 turn of the driven gear. 180 ÷ 6 = 30 RPM. A higher ratio reduces the output speed.

Question 3: A tension spring stretches 3.175 cm under load. What is this measurement in millimeters?

317.5 mm
31.75 mm (Correct answer)
3.175 mm
0.3175 mm

Correct answer: 31.75 mm

3.175 cm × 10 mm/cm = 31.75 mm.

Question 4: Two resistors of 8 ohms each are connected in series. What is the total resistance?

4 ohms
64 ohms
16 ohms (Correct answer)
8 ohms

Correct answer: 16 ohms

In a series circuit, resistances add directly: R_total = R1 + R2 = 8 + 8 = 16 ohms. Current must flow through each resistor in sequence, so their resistance values accumulate.

Question 5: Select the sentence that correctly uses 'lay' vs. 'lie.'

The wrench has been laying on the floor all morning.
He laid down after the long shift yesterday, laying his tools aside.
Please lay down on the gurney if you feel dizzy.
The manual lies on the supervisor's desk. (Correct answer)

Correct answer: The manual lies on the supervisor's desk.

'Lies' (present tense of 'lie') correctly describes an object resting in place without a direct object.

Question 6: Which sentence uses the word 'redundant' correctly in an elevator safety context?

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)
The redundant mechanic refused to work overtime.

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 7: An elevator cab weighs 3,000 lb and is lifted 40 feet in 20 seconds. The power required (ignoring losses) is approximately:

600 ft-lb/s (1.09 HP)
6,000 ft-lb/s (10.9 HP) (Correct answer)
120,000 ft-lb/s (218 HP)
3,000 ft-lb/s (5.45 HP)

Correct answer: 6,000 ft-lb/s (10.9 HP)

Power = Work/Time = (3,000 lb × 40 ft) / 20 s = 6,000 ft-lb/s; dividing by 550 gives ~10.9 HP.

Question 8: The load capacity L of a platform equals 3w + 50, where w is the width in feet. If L = 200 kg, find w.

50 (Correct answer)
40
60
45

Correct answer: 50

3w + 50 = 200 → 3w = 150 → w = 50 feet.

Question 9: In the sentence "The inspector conducted a preliminary assessment before issuing the final certification," the word "preliminary" most nearly means:

Mandatory and required
Thorough and detailed
Introductory and initial (Correct answer)
Final and conclusive

Correct answer: Introductory and initial

"Preliminary" comes from Latin meaning 'before the threshold.' It describes something done in preparation for the main event — an introductory step. The sentence contrasts it with "final," confirming it means initial.

Question 10: A wire is bent into an L-shape with one segment 6 inches long and the other 8 inches long meeting at a right angle. What is the straight-line distance between the two free ends?

12 inches
10 inches (Correct answer)
14 inches
7 inches

Correct answer: 10 inches

Using the Pythagorean theorem: c = √(6² + 8²) = √(36 + 64) = √100 = 10 inches.

Question 11: What is the result of 7/4 divided by 0.25?

3.5
7 (Correct answer)
5
1.75

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 12: A passage reads: 'The term rated speed describes the designed speed of the elevator car and its rated load in the up direction.' In which direction is rated speed measured?

Up (Correct answer)
Both up and down equally
The direction carrying the heavier load

Correct answer: Up

The passage explicitly states that rated speed is defined as the designed speed in the up direction.

Question 13: Which sentence uses 'affect' and 'effect' correctly?

The worn gear will affect the speed, and the effect could be dangerous. (Correct answer)
The effect of the worn gear affects nothing important.
The worn gear will effect the speed of the elevator.
The worn gear affects the effect of the motor's function.

Correct answer: The worn gear will affect the speed, and the effect could be dangerous.

'Affect' is the verb and 'effect' is the noun; both are used correctly in this sentence.

Question 14: In a roped hydraulic elevator, what is the purpose of the roping?

To provide emergency stopping power
To connect the cab to the governor
To multiply the travel distance of the plunger using a mechanical advantage (Correct answer)
To support the counterweight

Correct answer: To multiply the travel distance of the plunger using a mechanical advantage

Roping in a roped hydraulic elevator allows the cab to travel farther than the cylinder stroke by using a pulley-based mechanical advantage ratio.

Question 15: An elevator technician has a spool of wire that is 82.5 feet long. If they need to cut 12 pieces of wire that are each 6 1/4 feet long, how many feet of wire will be left on the spool?

7.5 feet (Correct answer)
10.0 feet
2.5 feet
12.5 feet

Correct answer: 7.5 feet

First, convert the mixed number to an improper fraction or a decimal. 6 1/4 feet is equal to 6.25 feet. Next, calculate the total length of wire needed by multiplying the number of pieces by the length of each piece: 12 pieces * 6.25 feet/piece = 75 feet. Finally, subtract the total length of wire used from the initial length of the spool: 82.5 feet - 75 feet = 7.5 feet.

Question 16: What is the next number in the series: 7, 14, 21, 28, ___?

35 (Correct answer)
33
32
36

Question 33: A passage reads: 'Hydraulic elevators use a pump and fluid to raise the car; the car descends by releasing fluid back to the reservoir through a control valve.' How does a hydraulic elevator car descend?

The counterweight pulls the car downward
The pump reverses direction
The car's weight pulls it down via the hoist rope
Fluid is released back to the reservoir through a control valve (Correct answer)

Correct answer: Fluid is released back to the reservoir through a control valve

The passage states descent occurs by releasing fluid back to the reservoir through a control valve, not by reversing the pump.

Question 34: 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)

15
12 (Correct answer)
10
11

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 35: A load chart for a traction elevator shows capacity ratings at different speeds: 2,500 lb at 100 fpm and 2,000 lb at 200 fpm. This relationship illustrates that in elevator specifications:

Load capacity and speed are often inversely related in rating tables (Correct answer)
Faster elevators always have higher load capacities
Load capacity increases proportionally with speed
Speed and capacity are identical regardless of configuration

Correct answer: Load capacity and speed are often inversely related in rating tables

Elevator rating tables frequently show that higher operating speeds correspond to lower rated load capacities due to motor and mechanical design constraints.

Question 36: A work order reads: 'Lubricate all guide rail fastenings prior to commencing the annual inspection.' When should lubrication occur?

During the inspection
After the inspection is complete
Only if fastenings appear dry
Before the inspection begins (Correct answer)

Correct answer: Before the inspection begins

'Prior to commencing' means before starting, so lubrication must happen before the inspection begins.

Question 37: A sign reads: 'This elevator is OUT OF SERVICE — do not use under any circumstances.' A freight delivery requires moving heavy materials to the 5th floor. What should the delivery crew do?

Use the elevator since freight is an exception
Call the building manager to override the sign
Use an alternative means such as stairs or another elevator (Correct answer)
Wait near the elevator until it is back in service

Correct answer: Use an alternative means such as stairs or another elevator

'Do not use under any circumstances' is absolute and allows no exceptions, so an alternative means must be used.

Question 38: When looking at a floor plan, a dashed line inside a room typically represents:

A wall that will be demolished
A sliding door track
An overhead feature or object above the cut plane (Correct answer)
An underground utility line

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

Question 45: The boy was filled with _______ when he saw that his sister broke his favorite toy.

Wrath (Correct answer)
Ambition
Joy
Confusion
Doubt

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 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?

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

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: When cutting the threads on a threaded rod used for hitch plate installation, which tool is used?

Threading machine only

Correct answer: failure

'Malfunction' means a failure to operate normally, which is closest in meaning to 'failure.'

Question 53: If a gear train consists of gears with 10, 20, and 40 teeth in series, what is the overall gear ratio from first to last?

2:1
1:8
1:4 (Correct answer)
1:2

Correct answer: 1:4

The overall ratio is (20/10) × (40/20) = 2 × 2 = 4, so the output gear turns at 1/4 the input speed (1:4).

Question 54: If you rotate a capital letter 'T' by 180 degrees, which letter does it most resemble?

Y
L
I
⊥ (an upside-down T) (Correct answer)

Correct answer: ⊥ (an upside-down T)

Rotating a T by 180 degrees produces an inverted T shape, which looks like the perpendicular symbol.

Question 55: A senior technician is writing a standard operating procedure. Which of the following instructions is written with correct parallel structure?

Before starting, you must lock out the power, tag the disconnect, and verify zero energy state. (Correct answer)
Your duties will be to answer service calls, perform routine maintenance, and submitting daily reports.
The job requires inspecting the wiring, to test the door sensors, and lubrication of the rails.
To troubleshoot the issue, you should be checking the fault codes, observe the motor, and to listen for strange noises.

Correct answer: Before starting, you must lock out the power, tag the disconnect, and verify zero energy state.

This sentence demonstrates correct parallel structure because all verbs in the series ('lock', 'tag', 'verify') are in the same base form. This creates a balanced and easy-to-read instruction. The other options mix different grammatical forms (e.g., inspecting, to test, lubrication; to answer, perform, submitting; checking, observe, to listen), which violates the rule of parallelism.

Question 56: Identify the sentence that contains a dangling modifier.

Before starting the lift, the operator checked the doors.
Having completed the inspection, he submitted the form.
After testing the brakes, the mechanic filed his report.
Walking to the machine room, the noise became louder. (Correct answer)

Correct answer: Walking to the machine room, the noise became louder.

In the second sentence, 'walking to the machine room' has no clear subject — it seems the noise was walking.

Question 57: A technical manual states: 'Lubricate the governor rope every 6 months or 50,000 cycles, whichever comes first.' A unit reaches 50,000 cycles in 4 months. When should it be lubricated?

At 8 months
At 6 months
Only when visible wear appears
At 4 months when it reaches 50,000 cycles (Correct answer)

Correct answer: At 4 months when it reaches 50,000 cycles

The unit hit 50,000 cycles at 4 months, which is earlier than the 6-month interval, so lubrication is due at 4 months.

Question 58: A gear system is designed to increase torque. If the driving gear has 12 teeth, which of the following driven gears would provide the greatest increase in torque?

A gear with 12 teeth
A gear with 48 teeth (Correct answer)
A gear with 6 teeth
A gear with 24 teeth

Correct answer: A gear with 48 teeth

To increase torque, the driven gear must be larger (have more teeth) than the driving gear. The gear ratio, which determines the mechanical advantage, is calculated by dividing the number of teeth on the driven gear by the number of teeth on the driving gear. A larger ratio results in a greater increase in torque. Comparing the options: 6/12=0.5 (decreases torque), 12/12=1 (no change), 24/12=2 (doubles torque), 48/12=4 (quadruples torque). Therefore, the 48-tooth gear provides the greatest torque increase.

Question 59: A square tile has a diagonal that measures 12 inches. What is the side length of the tile to the nearest inch?

10 inches
8 inches (Correct answer)
9 inches
6 inches

Correct answer: 8 inches

Side length = diagonal ÷ √2 = 12 ÷ 1.414 ≈ 8.5 inches, which rounds to 8 inches.

Question 60: If a lever has a mechanical advantage of 4 and the effort force is 50 lb, the load it can lift is:

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

Correct answer: 200 lb

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

Question 61: A code section states: 'Inspection certificates shall be conspicuously posted within the elevator car.' Where must the certificate be placed?

In the elevator machine room
In a clearly visible location inside the car (Correct answer)
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 62: Choose the word that best completes the analogy: Brake is to stop as cable is to ___.

drop
lock
suspend (Correct answer)
cut

Correct answer: suspend

A brake functions to stop movement; a cable functions to suspend the elevator car.

Question 63: A rectangular elevator pit is 4 feet deep, 6 feet wide, and 5 feet long. What is its volume in cubic feet?

96 cubic feet
110 cubic feet
140 cubic feet

Question 72: Since each person is _, collaborating as a team can bring results.

unique … superior (Correct answer)
different … continuous
talent … better
identical … inferior

Correct answer: unique … superior

Explanation: Since every person is unique (special), collaborating (working together) as a team can bring superior (better) results. The first pair of words is not a good match because "talent" is a noun while the sentence calls for an adjective describing the person. The third pair is incorrect because all people are not identical. The fourth pair is incorrect because the adjective "continuous" does not make sense in the context of the sentence. The last pair is incorrect because the word "diversity" is a noun and not an adjective.

125 fpm falls in the 51–150 fpm range, requiring a minimum pit depth of 4 feet.

Question 90: An elevator cab floor measures 5 feet by 7 feet. If the flooring material is sold by the square inch, how many total square inches of material are required to cover the entire floor?

5,040 sq in (Correct answer)
420 sq in
840 sq in
144 sq in

Correct answer: 5,040 sq in

First, calculate the area of the floor in square feet: 5 feet * 7 feet = 35 square feet. Since 1 foot is 12 inches, 1 square foot is 12 inches * 12 inches = 144 square inches. To find the total area in square inches, multiply the area in square feet by 144: 35 sq ft * 144 sq in/sq ft = 5,040 square inches.

Question 91: A guide rail section is 18 feet long. A technician cuts off 2.375 feet. How much remains?

Question 95: 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 96: A motor runs at 1,750 RPM. How many revolutions does it complete in 10 seconds?
