ASVAB MECHANICAL COMPREHENSION
TEST
To calculate force, multiply mass and acceleration.
vector quantities - ANSWER forces with size and direction.
Equilibrium is a stable situation in which forces cancel each other out.
Velocity is the speed and direction of a moving thing.
Acceleration is the rate at which velocity varies.
To calculate pressure, divide force (in pounds) by area (in inches).
Work = force × distance
Tension is measured in pounds of force or newtons.
Work is measured in - ANSWER foot-pounds.
Power is calculated by dividing work by time.
Power is measured in ANSWER horsepower (hp).
1 horsepower equals 33,000 foot-pounds per minute or 550 foot-pounds per
second.
Mechanical advantage occurs when a machine increases the force you employ.
Mechanical advantage. - Resistance ÷ effort = output force ÷ input force.
fulcrum - A point of support that reduces resistance and multiplies the effect of
effort.
