FLUID STATICS BOARD PROBLEMS

1. A car lift in a service station is used to lift a car of mass 1428.575 kilograms. If the diameter of the output piston is 12 centimeters and the diameter of the input piston is 2 centimeters, find the force needed to be supplied to the input piston in order to lift the car.

mg = 1428.575 kg

diam = 12 cm

diam = 2 cm
