ASVAB Mechanical Comprehension Test
ACTUAL Exam Questions and CORRECT
Answers
How much force is needed to lift the 10Kg weight?
A. 2 Kg
B. 5 Kg
C. 10 Kg
D. 20 Kg - CORRECT ANSWER - The correct answer is (B) 5 Kg. In a double-pulley
system, the force is equal to the weight divided by two. It will require a 5 Kg force to lift a 10Kg
weight.
The smaller gear has 8 teeth, and the larger gear has 16 teeth. When the larger gear makes 12
revolutions, how many revolutions will the smaller gear make?
See Picture
A. 8
B. 16
C. 18
D. 24 - CORRECT ANSWER - Question 2 Explanation: The correct answer is (D) 24. The
gear ratio here is 2:1, meaning that for every revolution of the larger gear, the smaller gear
revolves twice. If the larger gear revolves 12 times, the smaller gear will revolve twice as many
times.
Which of the following is the basis for Pascal's Law?
A. The amplification of force in a hydraulic system.
, B. The relationship between force and volume of a liquid.
C. The definition of pressure as pounds per square inch.
D. The manner in which liquids conform to their container. - CORRECT ANSWER - The
correct answer is (A) The amplification of force in a hydraulic system.
The third principle of hydraulics is the basis for Pascal's Law and states that when pressure is
applied to a fluid, the pressure is transmitted evenly throughout - in other words, how force is
amplified within a hydraulic system.
An 80-lb child is sitting on one end of a seesaw. If another 80-lb child jumps from a high
platform onto the other end of the seesaw, what will happen?
A. The first child will stay stationary on the ground.
B. The second child will bounce off the seesaw into the air.
C. The first child will bounce off the seesaw into the air.
D. The first child will be lifted into the air, but remain seated. - CORRECT ANSWER -
The correct answer is (D) The first child will be lifted into the air, but remain seated.
The force of the second child landing on the seesaw will propel the other end of the seesaw into
the air.
What is a vector quantity?
A. Gravity
B. Magnitude
