The Car Lift 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 5.03 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 12,500 N? SOLUTION Conceptualize Review the material about Pascal's law to understand the operation of a ca

Explanation:

The problem is based on the Pascal law . Pressure exerted by air will be transmitted to lift the car

Let force exerted by air be F

pressure by air = F / π r² , r is cross sectional area of small piston

= F /  (π x 5.03²)

Pressure by weight of car

= 12500 / (π x 12.7²)

The two pressures are equal .

F /  (π x 5.03²) =  12500 / (π x 12.7²)

F = 12500 x (5.03² / 12.7²)

= 1960.8 N

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
