ASVAB MECHANICAL COMPREHENSION
QUESTIONS AND ANSWERS
Torque is defined as the amount of force required to rotate an item and is
equivalent to horsepower.
C) push-pull
D) a force that moves in a circle - ANSWER A. the degree to which a force
causes an item to revolve
Speed differs from velocity because it is measured in metric units, whereas
velocity is measured in English ones.
B) Velocity includes both speed and direction.
C) Speed includes both velocity and direction.
D) Velocity is a scalar quantity (answer B). Velocity includes both speed and
direction.
Mechanical advantage is the advantage received by using ___________ to
convey force.
A: Power B: Transformer C: Mechanism D: Engine - Answer C: a mechanism.
Which of the following claims concerning weight is not correct?
A) Weight increases near the earth's surface. B) Weight is not only based on
mass.
C) Planets with higher masses have heavier weights. D) Weight varies by
location - ANSWER B. Weight is not entirely reliant on mass.
Which of the following is the mechanical advantage of a wheel and axle system
with a driven wheel radius of 10" and a drive wheel diameter of 5"?
Answer A: 4:1.
To apply more torque to a bolt, mechanics can use a longer wrench, use less
power, use a shorter wrench, or move the wrench more quickly (ANSWER A.
Use a longer wrench).
