    The formula of mechanical advantage in this situation is:

    MA = Input Force : Output Force

    The input force is the 30N applied to a screwdriver while the output force is the 75N force to the lid.

    So,

    MA = 30N/75N

    MA = 0.40

    Hence the mechanical advantage of the screwdriver is 0.40.
