Question

A hydraulic press has an input cylinder 4.0cm in diameter and an output cylinder 16cm in diameter. (a) Assuming 100 percent efficiency, find the force exerted by the output piston when a force of 170N is applied to the input piston.

Answer 1

Pressure is the same, and the area of the output is proportional to the ratio of diamenters squared, so
output force=(16/4)^2 *170N
= 16*170N
