A farmer is attempting to pull a log with a line of rope attached to a tractor. Where
should she watch for breakage on the rope?
a.)Nearest to the log
b.)Nearest to the tractor
c.)In the middle of the length
d.)No specific point on the length - ANSWER-b.)Nearest to the tractor
*The tension on the rope nearest to the tractor is the greatest. This is because
tension is greatest where the force is being applied.
Power is the
a.)Amount of force
b.)Rate of work
c.)Energy of an object
d.)Difference in resistance - ANSWER-b.)Rate of work
What is the advantage of a single pulley?
a.)It allows you to lift something with less force
b.)It changes the direction of the effort
c.)It diminishes the effects of gravity

d.)It decreases the chances of injury - ANSWER-b.) It changes the direction of the
effort
In terms of force, what makes hydraulic jacks so useful?
a.)The liquid is not very dense
b.)The liquid decreases the effects of gravity
c.)The liquid does not compress very much
d.)The jack spread out force over a large surface area - ANSWER-c.)The liquid does
not compress very much
*Hydraulic jacks are useful because the liquids used to transmit force do not
compress, even under high pressure. Instead, that force is transmitted to another
location.
Jeremy chucks a baseball as far as he can. His arm is operating as a
a.)First-class lever
b.)Second-class lever
c.)Third-class lever
d.)Fourth-class lever - ANSWER-c.)Third-class lever
What is the mechanical advantage of a teeter-totter built so that each seat is 2
meters from the fulcrum?
a.)2:2
b.)4:2
2|Page
, ASVAB: Mechanical Comprehension Exam
c.)2:4
d.)1:2 - ANSWER-a.)2:2
*The mechanical advantage is the ratio of the distance between the fulcrum and
the point at which force is applied, and the distance between the fulcrum and the
object being acted upon.
Weight is the
a.)Amount of "stuff" in an object
b.)Density of matter in an object
c.)Gravity generated by an object
d.)Force exerted on a object due to gravity - ANSWER-d.)Force exerted on a object
due to gravity
*Mass is the amount of matter in an object; weight is the force exerted on an
object due to gravity.
If a large gear drives a smaller gear, which of the following will not occur?
a.)An increase in rotational speed
b.)A decrease in torque
c.)A change in rotational direction
d.)A change in gear ratio - ANSWER-d.)A change in gear ratio

, ASVAB: Mechanical Comprehension Exam
*The ratio of the gears (a comparison of the number of teeth on the gears) will
remain the same.
"For every action there is an equal and opposite reaction" best summarizes which
of Newton's Laws of Motion?
a.)Newton's First Law
b.)Newton's Second Law
c.)Newton's Third Law
d.)None of the above - ANSWER-c.)Newton's Third Law
*Newton's third law explains that for every action there is an equal and opposite
reaction.
How is a wedge different from an inclined plane?
a.)The angles of a wedge are generally smaller
b.)A wedge provides more mechanical advantage
c.)A wedge compounds force
d.)A wedge is used in motion - ANSWER-d.)A wedge is used in motion
*A wedge, unlike a slide, is useful in motion. For example, a knife slicing through a
carrot.
What's the formula of force?
a.)P=f/a
