A hydraulic lift in a garage has two pistons: a small one of cross-sectional area 4.10 cm2 and a large one of cross-sectional area 230 cm2.
Part A: If this lift is designed to raise a 3700 kilogram car, find what minimum force must be applied to small piston?
Part B: If the force is applied through compressed air, find what must be the minimum air pressure applied to the small piston?
