When the input piston of a hydraulic press is depressed 20 cm,the output piston is observed to move 1 cm.An input force of 1 N can raise no more than

Question

Quizplus · Accepted Answer

The hydraulic press operates on the principle of conservation of energy and Pascal's law. The work done on the input piston is equal to the work done by the output piston. Since the input piston moves 20 times the distance of the output piston, the force exerted by the output piston is 20 times the input force. Therefore, an input force of 1 N can raise a maximum of 20 N.
