Question
Given: Hydraulic systems utilize Pascal's principle by transmitting pressure from one cylinder (called the primary) to another (called the secondary). Since the pressures will be equal, if the surface areas are different then the forces applied to the cylinders' pistons will be different. Suppose in a hydraulic lift, the piston of the primary cylinder has a 1.95-cm diameter and the piston of the secondary cylinder has a 25.5-cm diameter.
What force, in newtons, must be exerted on the primary cylinder of this lift to support the weight of a 1750-kg car (a large car) resting on the secondary cylinder?

- Verify that work input equals work output for a hydraulic system assuming no losses due to friction. Do this by showing that the distance the output force moves is reduced by the same factor that the output force is increased. Assume the volume of the fluid is constant.

How would this depend on whether or not the fluid is moving?arrow_forwardA hydraulic piston has two surfaces which can move when a force is applied to them.
