In a car lift used in a service station, com-
pressed air exerts a force on a small piston
of circular cross-section having a radius of
4.07 cm. This pressure is transmitted by a
liquid to a second piston of radius 15.2 cm.
What force must the compressed air exert
in order to lift a car weighing 12600 N?
Answer in units of N.
part b.
What air pressure will produce this force?
Answer in units of Pa.
