wedge and screws quiz

input distance

along the threads

output force

along the threads pushing the screw up or down

mechanical advantage of a screw

diagonal length of threads divided by height of screw

screw

inclined plane wrapped around a cylinder simple machine that turns rotating motion into linear motion works just like a ramp that curves as it gets higher

wedge

input force exerted downward on it results in output forces that can split the object device that is thick at one end and tappers to a thin edge at the other end inclined plane itself moves

mechanical advantage of a wedge

slope length divided by width longer and thinner it is, the greater the mechanical advantage is greater

threads

spiral inclined plane

input force

top of the screw

output distance

vertical height of the threads
