ASVAB 2024-2025 (Mechanical
Comprehension) Questions With Correct
Answers
Fluid pressure is also known as _______ pressure. - answer✔hydraulic
What is the formula for calculating friction? - answer✔Ff = μFn
where Ff= force of friction, μ= coefficient of static/kinetic friction, and Fn=normal force
What is the formula for calculating pressure applied evenly to a surface? - answer✔P = F/A where P
represents the P represents pressure expressed in pounds of force per square inch, F represents force in
pounds and A represents area in square inches.
____ is the common term for the force that opposes movement through air or liquid - answer✔drag
How would you increase the mechanical advantage of a wheel and axle arrangement? - answer✔by
increasing the ratio of the diameter of the large wheel to that of the small wheel
When two surfaces rub together, _____ friction results. - answer✔kinetic
what does the work-energy theorem say - answer✔any work done to move an object from a resting
position to a certain velocity will be converted into the kinetic energy of that object.
What primarily determines the mechanical advantage of a block and tackle - answer✔the number of
pulleys
in hydraulics, pascal's law states that - answer✔the pressure in any part of an enclosed fluid is the same
and points in all directions.
what is the formula for calculating gravitational potential energy? - answer✔PE = mgh, where m
represents the mass of the object in kg, g is acceleration due to gravity (~9.8 m/s^2), and h is the height
of the object in meters.
in a first-class lever, where is the fulcrum and where is the force applied? - answer✔the fulcrum is
positioned in the middle of the lever. Force is applied to one end of the lever to lift an object on the
other end.
