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?

Sagot :

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.
