Question:

Compressed air in a car lift applies a force to a piston with radius 5.00 cm. This pressure is transmitted through a hydraulic system to a second piston with radius 15.0 cm.
(a) How much force must the compressed air exert to lift a vehicle weighing 1.33 x 104 N?
(b) What pressure produces the lift?
