The Hydraulic Press
A hydraulic press is a machine made of two pistons with different cross-sectional areas ( and ), which is used to lift large weights or compress material.[more]
The ratio of the distances moved and the ratio of the forces are both equal to the ratio of the areas of the pistons.
The large piston is the one that does the "useful" work of crushing things.[less]
