physics working model on hydraulic lift pdf

A hydraulic lift is a simple machine that uses the transfer of pressure through an enclosed static liquid medium (usually an oil of some sort) to lift heavy machinery. In accordance with Pascal's principle, the pressure is transmitted from one end of the hydraulic lift to the other undiminished. When the area of the piston that receives the pressure is larger than that of the initial piston, the upward force exerted by the second piston is several times stronger than the downward force exerted on the first piston.
