A hydraulic lift in a garage has two pistons: a small one of cross-sectional area 4.50 cm2 and a large one of cross-sectional area 220 cm2.
Part A. If this lift is designed to raise a 3400 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?
