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)

A) A 1500-kg car is lifted to a height h by a hydraulic lift
containing an incompressible fluid. A force of F_1 applied on a
piston of area A_1 results in a larger force of F_2 on the plunger
of larger area A_2. Suppose the piston has a radius of 0.0120 m and
the plunger’s radius is 0.150 m. Calculate the height to which the
car is lifted if the work done by the plunger is 200 J. (Assume
