Question

The input piston and output plunger of a hydraulic car lift are at the same level, as shown in the drawing. The cross-sectional area of the input piston is 12 cm2, while that of the output plunger is 1200 cm2. The force F1 applied to the input piston has a magnitude of 170 N. What is the weight W of the car? Neglect the weight of the piston and plunger.
