Answer:
Mechanical advantage = 3
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,
[tex]m=\dfrac{300}{100}\\\\m=3[/tex]
Mechanical advantage is 3 it means that there are 3 sections of rope support. Hence, this is the required solution.
