Hydraulic jacks and hydraulic brakes obey Pascal's law. In a hydraulic jack, two connected cylinders of different diameters are filled with an incompressible fluid. Recall that pressure equals force per unit area. When a force is applied to the smaller cylinder, the pressure in the fluid increases throughout the fluid, causing the fluid to apply a larger force on the surface of the cylinder with the larger area. = = P= A small F small = A big F big Rearranging gives a relationship for the force at the surface of the bigger cylinder: = F big =F small A small A big Therefore, a small force at the handle of the jack transmits a bigger force on the weight that is lifted by the jack
