Abstract

A machine is any device which enables mechanical work to be done more easily. Very often this results in a small applied force being amplified into a large one, for example when a screwdriver is used to ‘lever’ a lid off a tin. Sometimes a small movement is amplified into a large one, as in a bicycle when a small pedal movement results in a much larger movement of the bicycle along a road.
