    Answer:

    4

    Explanation:

    Mechanical advantage is defined as the ratio of the load to the effort applied to raise the load. If minimal effort is used to overcome a much larger load, that is when we have what is called mechanical advantage i.e a machine has been used to our advantage.

    Mathematically, MA =  Load/Effort

    Given parameters

    Load = 160N

    Effort = 40N

    Required

    Mechanical Advantage

    Using the formula above

    MA = 160N/40N

    MA = 4

    advantage
