Answer: Mechanical advantage can be achieved just by adding more loops or pulleys.
It is given that to lift a crate, a pulley system exerts a force of 2,750 newtons.
It is required to find the mechanical advantage of the pulley system if the input force is 250 newtons
What is the mechanical advantage of the pulley system if the exerted force changes from 2,750 newtons to 250 newtons?
As if the force does some work, it increases the distance. Mechanical advantage does nothing with the number of pulleys. It only depends on the weight that is to be lift.
Also,
[tex]\frac{F_{1} } {F_{2} }=\frac{2750}{250}=11[/tex]
The multiple pulleys create mechanical advantage. It can be achieved just by adding more loops or pulleys.
Therefore, Mechanical advantage can be achieved just by adding more loops or pulleys.
