Pascal's law is a law of hydrostatics indicates when any point in a incompressible static fluid is pressed by external force and increased pressure is generated, the increased pressure will immediately be transmitted to every point of the static fluid. According to Pascal's Law, if there are two pistons, one big, one small in one fluid system, the intensity of pressure on the two pistons must be equivalent. Intensity of pressure equals acting force over stressed area. If a low thrust is imposed on the smaller piston, a higher thrust will be generated onto the bigger piston through pressure transmission inside fluid.
