In a car lift used in a service station, pressure is transmitted by an incompressible liquid from a small piston of circular cross section with a radius of r1 = 5.00 cm to a second piston of radius r2 = 15.0 cm. Calculate the minimum force that must be exerted on the smaller piston to lift a car weighing 13300 N.
