in a hydraulic lift, if the radius of the smaller piston is 2.0 cm and the radius of the larger piston is 20.0 cm, what weight can the larger piston support when a force of 250 N is applied to the smaller piston? what is the increase in pressure caused by the 250 n force on the small piston? If the larger piston moves 5.0 cm how far does the smaller piston move?
