A 14 500-N car on a hydraulic lift rests on a cylinder with a piston of radius 0.100 m.If a connecting cylinder with a piston of 0.050-m radius is driven by compressed air,what force must be applied to this smaller piston in order to lift the car?

Question

Quizplus · Accepted Answer

The force on the smaller piston must be equal to the force on the larger piston, which is equal to the weight of the car. So, the force on the smaller piston must be 14 500 N.
