Question

A pulley is used to raise a heavy crate. The pulley is such that an input force of 223 N is needed to provide an output force of 1784 N. What is the mechanical advantage of this pulley?

a. 8.00
b. 7.00
c. 8.04
d. 7.99

Answer 1

The mechanical advantage of the pulley is 8.00.

Step-by-step explanation:

The mechanical advantage of a pulley can be calculated by dividing the output force by the input force. In this case, the input force is 223 N and the output force is 1784 N. Therefore, the mechanical advantage of the pulley is 1784/223 = 8.00.
