PRACTICE IT Use the worked example above to help you solve this problem. In a car lift used in a service station, compressed air exerts a force on a small piston of circular cross section having a radius of r = 4.55 cm. This pressure is transmitted by an incompressible liquid to a second piston of radius 13.7 cm. (a) What force must the compressed air exert on the small piston in order to lift a car weighing 13,300 N?...

LEARN MORE REMARKS In this problem, we didn't address the effect of possible differences in the helghts of the pistons. If the column of fluid is higher in the small piston, the fluid weight assists in supporting the car, reducing the necessary applied force. If the column of fluid is higher in the large piston, both the car and the extra fluid must be supported, so additional applied force is required. QUESTION if the radius of the output piston is...
