Mechanical ASVAB Exam with 100% accurate detailed 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
|| || || || || || || || || || || ||
