hydraulic machine

CE5

Hydraulic pressure: In any hydraulic device the pressure exerted by one piston is transmitted throughout the fluid. Since pressure equals force divided by area, a small force (F₁) exerted on a piston of small surface area (A₁) results in a large force (F₂) being exerted on a second piston of large surface area (A₂).

hydraulic machine, machine that derives its power from the motion or pressure of water or some other liquid.
