The Small Piston of a Hydraulic Lift Has a Diameter

Short Answer

The small piston of a hydraulic lift has a diameter of 8.0 cm,and its large piston has a diameter of 40 cm.The lift raises a load of 15,000 N.Assume the pistons each have negligible mass.
(a)Determine the force that must be exerted by the fluid in the lift on the small piston.
(b)Determine the pressure applied to the fluid in the lift.
