Question

A system of pulleys is used to raise a heavy crate. The pulley system 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 system?

Answer 1

The mechanical advantage of the pulley system is approximately 8.

Step-by-step explanation:

The mechanical advantage of a pulley system is determined by the ratio of the output force to the input force. In this case, the output force is 1784 N and the input force is 223 N. To calculate the mechanical advantage, we divide the output force by the input force:

Mechanical Advantage = Output Force / Input Force

Mechanical Advantage = 1784 N / 223 N

Mechanical Advantage ≈ 8

Therefore, the mechanical advantage of this pulley system is approximately 8.
