In car lift compressed air exerts a forc...

In car lift compressed air exerts a force `F_1` on a small piston having a radius of 5 cm. This pressure is transmitted to a second piston of radius 15 cm. If the mass of the car to be lifted is 1350 kg, what is `F_1 ?` What is the pressure necessary to ac complish this task ?

A

`14.7xx10^(3)N`

B

`1.47xx10^(3)N`

C

`2.47xx10^(3)N`

D

`24.7xx10^(3)`N

Text Solution
