In a hydraulic garage lift, the small piston has a radius of 4.0 cm and the large piston has a radius of 20 cm. what force must be applied on the small piston in order to lift a car weighing 20,000 n on the large piston? assume the pistons each have negligible weight.

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.
