Larger output piston gives a larger force
Links theory to hydraulic presses, jacks, brakes and lifts
About This Product
Pressure applied through the input piston is transmitted through the confined liquid and acts on the output piston. Because the transmitted pressure is equal, force is proportional to piston area, so in an ideal system a larger output piston gives more force than the input. With the model on a level bench, students operate the input and watch the output piston respond, then relate this to hydraulic presses, jacks and brakes.
Frequently Asked Questions
Q1. Why does a hydraulic press multiply force? The same pressure acts on both pistons and force is proportional to piston area, so the larger output piston produces a greater force than the input in an ideal system.
