Question

In a car lift, compressed air exerts a force F 1 ​ on a small piston having a radius of 5.0 cm . This pressure is transmitted to a second piston of radius 10.0 cm . If the mass of the car to be lifted is 1350 kg . The force on a small piston is

Here, r 1 ​ = 100 5 ​ m , F 2 ​ = 1350 kg = 1350 × 9.8 N , r 2 ​ = 100 10 ​ m According to Pascal law, As, A 1 ​ F 1 ​ ​ = A 2 ​ F 2 ​ ​ or F 1 ​ = A 2 ​ A 1 ​ ​ F 2 ​ = π r 2 2 ​ π r 1 2 ​ ​ F 2 ​ or F 1 ​ = r 2 2 ​ r 1 2 ​ ​ F 2 ​ = ( 100 10 ​ ) 2 ( 100 5 ​ ) 2 ​ × 1350 × 9.8 = 1470 N
