In a hydraulic system, piston 1 has a surface area of 100 cm2, and piston 2 has a surface area of 900 cm2. a force of 150 n is exerted on piston 1 of the hydraulic lift. what force will be exerted on piston 2?

From Pascal's law, we can say that the pressure exerted by piston 1 on the fluid will be transmitted with equal intensity to piston 2:
(1)

The relationship between the pressure applied p, the force applied F and the surface A is


So we can rewrite (1) as

And from this, we can find the magnitude of the force exerted on piston 2, F2:
