Answer:
The mechanical advantage is 3 to 1
Explanation:
A frictionless pulley with three support ropes carries equal tension on each of the ropes thus;
Tension in each pulley rope = T
Total tension in the 3 ropes = 3 × T = 3·T
Direction of the tension forces on each rope = Unidirectional
Total force provided by the 3 ropes = 3·T
Therefore, a force, T, applied at the end of the rope will result in a lifting force of 3·T
Hence, the mechanical advantage = 3·T to T which is presented as follows;
![Mechanical \ advantage = \dfrac{3 \cdot T}{T} = \dfrac{3}{1}](https://tex.z-dn.net/?f=Mechanical%20%5C%20advantage%20%3D%20%5Cdfrac%7B3%20%5Ccdot%20T%7D%7BT%7D%20%20%3D%20%5Cdfrac%7B3%7D%7B1%7D)
The mechanical advantage = 3 to 1.
