A. What must be the ratio of the diameter of the vessel at the car to the diameter of
the vessel to the force Fi is applied so that a 1200kg car can be lifted with a force
F1 of just 120N?
B. The piston of the hydraulic automobile lift is 0.5m in diameter. What gauge
pressure, in Pascal, is required to lift a car with a mass of 1200kg?
C. What is this pressure in atmospheric pressure (atm)? Note: 1Pa = 9.87x10-6atm
2. If the area of Piston 1 is A1 = 0.028 m2, the area of Piston 2 is Az = 0.55 m2 and the
external input force F1 = 420 N, what is the external output force F2?​
