Question

A pulley was used to lift wood that weighed 3892 N. The force applied to the pulley was 274 N. What is the mechanical advantage of the pulley?

Answer 1

1946/137

Step-by-step explanation:

I would say this would go under physics rather than biology.

The mechanical advantage is found by the ratio of the output force to the input force. Writing this as an equation will be MA = F_o/F_i where F_o is the output force and F_i is the input force. Solving for MA with the information we have, we get: MA = 3892/274 = 1946/137
