A lever has an effort arm that is 8 meters long and the residence (load) arm that is 1.5 meters long, how much effort is needed to lift a 200 newton weight?

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
