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
