A multiple-piston hydraulic jack has two output pistons, each with an area of 250 cm^2. The input piston, whose area is 25 cm^2, is concerned to a lever that has a mechanical advantage of 9:1. if a 50-N force is exerted on the lever, how much pressure ( KN/m^2 ) is developed in the system? How much force ( KN) will be exerted by each output piston?
