Mechanical ASVAB Exam Study Guide Solutions
force - ✔✔Changes the velocity of an object
friction - ✔✔Acts in opposition to motion, causes effort work to be larger than load work
equilibrium - ✔✔Net force is zero when velocity is not changing
viscous drag - ✔✔Like friction, however increases with speed, varies by shape
gravity - ✔✔Causes objects to fall
mass - ✔✔Amount of substance
weight - ✔✔Force of gravity on a mass
lift - ✔✔Caused by higher speed air flow over a lower speed air flow
camber - ✔✔When a surface is curved
airfoil - ✔✔Shape of a wing, fan or propeller
leading edge - ✔✔Part that meets airflow first
upwash - ✔✔Airstream that's directed upward
trailing edge - ✔✔Where upper and lower airflow meet
downwash - ✔✔Airstream directed downward
thrust - ✔✔One of four airplane forces which goes forward
drag - ✔✔One of four airplane forces which goes backward
elastic recoil - ✔✔The "reaction" force when pushing on a solid

, tension - ✔✔Rope under a force
tension rule - ✔✔Tension is the same throughout
buoyancy - ✔✔If the weight of an object is less than the weight of the fluid it displaces, it will rise
negative buoyancy - ✔✔If the weight of an object is greater than the weight of the fluid it displaces
fluid - ✔✔Air is one
action and reaction - ✔✔Forces exist only in pairs
components of force - ✔✔The smaller the angle, the larger the effective force
component of force rule - ✔✔Only the component action in the direction the sled is going does work
inclined plane - ✔✔Weight of the stroller acts parallel and normal to the surface
inclined plane rule - ✔✔Total force to keep stroller moving is equal to parallel component plus friction
parallel - ✔✔Going along the surface
normal - ✔✔Going into the surface
simple machines - ✔✔Pulleys, levers, jacks, hydraulics, vises, ramps, vises, cranks, gears
pulley - ✔✔With single, effort is half the load and effort distance is twice the load distance
load - ✔✔Object being lifted
load distance - ✔✔Distance lifted object moves
effort - ✔✔Force exerted
effort distance - ✔✔Distance force is exerted
work - ✔✔Force moving over a distance
