The large piston in a hydraulic lift has an area of 250 cm2. What force must be applied to the small piston with an area of 25 cm2 in order to raise a car of mass 1500 kg?

Explanation:

Given that,

Area of large piston,

Area of small piston,

Force applied to large piston,

It is required to find the force applied to the small piston. The pressure in each chamber must be equal so, that,

F₂ is force applied to smaller piston

So, the force of 150 kN must be applied to the small piston.
