A car lift in a garage uses incompressible oil. A small input piston of radius 4.00 cm is connected to a large piston of radius 16.00 cm via a sealed chamber. The large piston is connected to a platform on which rests a car. The combined mass of the platform and car is 1500 kg.
(a) What is the minimum force required at the input piston to begin to raise the car?
(b)What pressure is exerted at the small piston with this minimum force applied?
(c) What pressure is exerted at the large piston with this minimum force applied?
(d) What distance would the small piston need to move for the large piston to rise by 1.0 cm?
(e) What work is done in raising the large piston by 1.0 cm? Assume the force applied is the minimum force calculated in (a)
This questions can be solwed using pascals law state that pressure of liquid is equally distributed.
