Question

You exert a 100-N force on a pulley system to lift 300-N. What is the mechanical advantage of this system? How many sections of rope support weight?

Answer 1

Mechanical advantage = 3

Step-by-step explanation:

You exert a 100-N force on a pulley system to lift 300-N.

The mechanical advantage of the system is given by the ratio of output force to the input force.

Here, output force = 300 N and input force = 100 N

Mechanical advantage,

`m=(300)/(100)\\\\m=3`

Mechanical advantage is 3 it means that there are 3 sections of rope support. Hence, this is the required solution.
