Compressed air in a car lift exerts a force on a small piston of circular cross section having a rad
Compressed air in a car lift exerts a force on a small piston of circular cross section having a radius of r1 = 10 cm. This pressure is transmitted by an incompressible liquid to a second piston of radius r2 = 20 cm. What force must the compressed air exert on the small piston in order to lift a car weighing 15,500 N? [The weights of the pistons are negligible.]
