1. A 13 000-N car on a hydraulic lift rests on a cylinder with a piston of radius 0.10 m. If a connecting cylinder with a piston of 0.040-m radius is driven by compressed air, what force must be applied to this smaller piston in order to lift the car?
 a. 13 000 N b. 81 N c. 2 580 N d. 2 080 N e. 1 980 N

Pressure on large piston = Pressure On small piston

13000/0.1^2 = F/0.04^2

hence F = 2080 N
