In a car lift used in a service station, compressed air exerts a force on a small piston that has a circular cross section of radius 5.83 cm. This pressure is transmitted by a liquid to a piston that has a radius of 12.7 cm. (a) What force must the compressed air exert to lift a car weighing 13,500 N? SOLUTION Conceptualize Review the material about Pascal's law to understand the operation of a car lift. problem. Categorize This example is a substitution F₁ F₂ A₁ A₂ ^-^)^₂-0 F₁ Solve -for F₁ (in N): (b) What air pressure produces this force? SOLUTION Use the definition of pressure to find the air pressure (in Pa) that produces this force: P= Pa This pressure is -Select-- than the atmospheric pressure.
