Quizplus · Accepted Answer

The hydraulic press operates based on Pascal's principle, which states that pressure applied to a confined fluid is transmitted undiminished throughout the fluid. The mechanical advantage is given by the ratio of the distances moved by the pistons. Here, the input piston moves 20 cm and the output piston moves 1 cm, giving a mechanical advantage of 20. Therefore, an input force of 1 N can raise an output force of 20 N.
