1) What force will the large piston provide if the small piston in a hydraulic lift is moved down as shown in the figure?

2) If the small piston is depressed a distance of ?y1, by how much will the large piston rise?

3) How much work is done in slowly pushing down the small piston if ?y1 = 0.18 m?

The hydraulic lift (the figure below) has a small piston with the surface A = 0.029 m and a large piston with the surface A = 3.0 m. F = 14 N. F 1 A 111- F = ? A Ay2
