Consider a 1,000-kg car that is going to be lifted by a hydraulic hoist. The diameter of the piston and cylinder of the hoist itself is 20 cm. A line runs to a hydraulic pump that has a piston and cylinder with a diameter of 2 cm. What force must be exerted on the piston at the hydraulic pump to lift the car?

Consider the hydraulic pump and the hoist to be at the same height or elevation.
