    Answer: The force that must be applied is 80N

    Step-by-step explanation:

    Here, we are talking about simple machines; a screw is an example of a simple machine. Other examples include lever, nail puller, wheelbarrow, crank, etc.

    Here, we are talking about simple machines; a screw is an example of a simple machine. Other examples include lever, nail puller, wheelbarrow, crank, gear, etc.

    Simple machines are devices that can be used to multiply or augment a force that we apply - often at the expense of a distance through which we apply the force.

    The mechanical advantage for any simple machine is the ratio of output to input force magnitudes. That is,

    Mechanical advantage (MA) = Force output / Force input

    From the question,

    Mechanical advantage (MA) = 12.5

    Force output = 1000N

    Force that must be applied, that is, force input = ?

    Therefore,

    12.5 = 1000N / Force input

    Force input = 1000N/12.5

    Force input = 80N

    Hence, the force that must be applied is 80N
