Answer to Question #106568 in Mechanics | Relativity for Adam Yaacoub

Question

In a hydraulic press, the area of the small piston is 25.0 cm2 and the area of the large piston is 325 cm2. If a force of 75.0 N is exerted on the small piston, find the weight of the object that can be lifted by the large piston.

Answer 1

We use Pascal’s principle $\frac {F_1}{A_1}=\frac {F_2}{A_2}; F_2=F_1\times\frac{A_2}{A_1}; F_2=75 N \times \frac{325 {cm^2}}{25 {cm^2}}; F_2=975 N; Answer: 975 N$
