An applied pressure change is transmitted throughout an enclosed static fluid. An ideal hydraulic lift uses a larger output area to produce a larger output force. The output piston moves a shorter distance, preserving energy in the ideal case.

Calculate ideal force multiplication.
Relate piston force to piston area.
An ideal hydraulic lift has input area 0.0100 m² and output area 1.00 m². Find the output force for an applied input force of 10.0 N.
