Question

What is the IMA of this pulley belt system if the diameter of the input
pulley is 2.5 inches and the diameter of the output pulley is 7 inches?

Answer 1

Answer:

2.8

Explanation:

The ideal mechanical advantage of the pulley IMA  = D'/D where D' = diameter of output pulley = 7 inches and D = diameter of input pulley = 2.5 inches

So, IMA = D'/D

= 7/2.5

= 2.8

So, the ideal mechanical advantage of the pulley IMA = 2.8
