EEI TECH EEI Tech Reasoning 2 — Questions and Answers
Question 1: A pump is rated to move 50 gallons per minute. How many gallons will it move in 12 minutes of continuous operation?
- 500
- 600 (Correct answer)
- 550
- 720
Correct answer: 600
50 gallons/minute × 12 minutes = 600 gallons.
Question 2: If gear A turns clockwise and meshes directly with gear B, which direction does gear B turn?
- Clockwise
- Counterclockwise (Correct answer)
- It does not turn
- Both directions alternately
Correct answer: Counterclockwise
Two directly meshed gears always rotate in opposite directions.
Question 3: A circuit has a 12-volt source and a resistance of 4 ohms. Using Ohm's law, what is the current?
- 48 amps
- 3 amps (Correct answer)
- 8 amps
- 16 amps
Correct answer: 3 amps
Current = Voltage ÷ Resistance = 12 ÷ 4 = 3 amps.
Question 4: Which simple machine is best represented by a ramp used to roll a barrel onto a truck?
- Pulley
- Inclined plane (Correct answer)
- Wheel and axle
- Screw
Correct answer: Inclined plane
A ramp is an inclined plane that reduces the force needed to raise a load.
Question 5: In the number series 2, 6, 12, 20, 30, what comes next?
- 36
- 40
- 42 (Correct answer)
- 44
Correct answer: 42
The differences increase by 2 each time (4,6,8,10,12), so 30 + 12 = 42.
Question 6: A lever has its fulcrum in the middle with equal arm lengths. To balance a 40-pound weight on one side, how much force is needed on the other side?
- 20 pounds
- 40 pounds (Correct answer)
- 80 pounds
- 10 pounds
Correct answer: 40 pounds
With equal arm lengths, the balancing force equals the load: 40 pounds.
Question 7: Two pulleys are connected by a belt. The driver pulley is larger than the driven pulley. The driven pulley will turn:
- Slower than the driver
- Faster than the driver (Correct answer)
- At the same speed
- In the opposite direction only
Correct answer: Faster than the driver
A smaller driven pulley rotates faster than a larger driver pulley.
