Question

Why is the mechanical advantage of this machine pully is less than 1 , 2 line ans only

Answer 1

Answer:

3rd class

Explanation:

The mechanical advantage of a 3rd class lever is always less than 1. For this class of levers, the input effort is higher than the output load, which is different from second-class levers and some first-class levers. However, the distance moved by the load is greater than the distance moved by the effort.
