Answer:

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
