Question

In a hydraulic lift, the surface area of the input piston is 10 cm² . The surface area of the output piston is 3000 cm² . A 100 N force applied to the input piston raises the output piston. Calculate the force required to raise the output piston.

Answer 1

Pressure input on piston,

According to Pascal’s law 

P = \(\frac{F}{A}\) P = \(\frac{F}{A}\) 

10⁵ = \(\frac { F }{ 3000 \times 10 }\)= \(\frac { F \times 10 }{ 3000 }\) 

l0^-4 x F = 10⁵ x 3000 

F = 3000×10¹ 

= 3 x 10⁴ N
