    1066.67 N

    Explanation:

    Given that two measurements of the arm and an input weight. To answer this problem, we need to balance the forces and use the lengths of the arms.

    Force * effort of arm distance = input weight * load distance

    200 N * 8 m = x * 1.5 m

    1600 = 1.5x

    x = 1600/1.5

    x = 1066.666 N

    it takes 1066.67 N to lift the input weight
