Question #271260

A hydraulic press has a small piston of diameter =3.4 cm and the large piston of diameter=30 cm. If the force applied to the small piston (F1) is 395 N.

What is the mass of the car that can be raised at the large piston (in kg)?

Expert's answer

\frac{mg}{R^2}=\frac{F}{r^2}\\\frac{9.8m}{30^2}=\frac{395}{3.4^2}\\m=3138\ kg
