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 140 N. What is the weight W of the car? Neglect the weight of the piston and plunger.
use this formula: F1/A1 F2/A2 140/12 F/1200 11.67 F/1200 F 14,000N weight of the car is 14,000N
