In a car lift used by a service station , compressed air exerts a force on a small piston of radius 5 cm. This pressure is transmitted to a second piston of radius 15 cm. What force must the compressed air exert on the small piston to lift a car whose mass is 1200kg?What compressed air pressary to produce this force? Is this a reasonable answer? Explain.

A steel safe of weight 1.00 x 10 4 N. is being raised to the top of a building. The steel cable to be used was only 15 m long and so an additional 7 m length of another cable had to be used. If both cables have a diameter of 1.00 cm, and the total stretch of both cables put together is 2.35 cm, what is the Young,s modulus of the second cable?The weight of both cables is negligible compared to that of the safe.
