What is the maximum weight that can be lifted by a pulley with a mechanical advantage of 3 when a force of 160 pounds is applied?

To determine the maximum weight that can be lifted by a pulley with a mechanical advantage of 3 when a force of 160 pounds is applied, you need to understand the concept of mechanical advantage. Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device, or system.

In this case, a mechanical advantage of 3 means that the pulley system allows you to lift a weight that is three times the amount of the force you are applying. Therefore, if you are applying a force of 160 pounds, the maximum weight that can be lifted is calculated by multiplying that force by the mechanical advantage:

( Maximum , Weight = Force \times Mechanical , Advantage )

Substituting the provided values:

( Maximum , Weight = 160 , pounds \times 3 = 480 , pounds )

Thus, the maximum weight that can be lifted in this scenario is 480 pounds.
