Question

    Which of the following is the principle behind the

    working of a hydraulic press?  
    A Archimedes' principle Correct Answer Incorrect Answer
    B Pascal's law Correct Answer Incorrect Answer
    C Boyle's law Correct Answer Incorrect Answer
    D Bernoulli’s principle Correct Answer Incorrect Answer

    Solution

    The working of a hydraulic press is based on Pascal's law, which states that any change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.   This principle allows a small force applied to a small piston to generate a much larger force on a larger piston.
