According to Pascal's law, the pressure applied to a confined fluid is transmitted undiminished to all parts of the fluid and to the walls of the container. Therefore, if the force is applied to the smaller piston, it generates a higher pressure, which is transmitted to the larger piston. As the pressure is the same throughout the fluid, the larger piston will have a greater force, which is proportional to its area. Thus, the output force on the larger-area piston will be more than the input force on the smaller piston.
