Question

State the factors which make the mechanical advantage less than velocity ratio

Answer 1

The mechanical advantage(M.A) of a real machine is always less than itsvelocity ratio(V.R) because mechanical advantage decreases due to the friction and weight of moving parts of the machine whereas the velocity ratioremains constant. ... Because of friction, air resistance, this Ideal situation would never be achieved.

Answer 2

The factors that makes the mechanical advantage less than the velocity ratio are :

1. Frictional Force

2. Gravity

3 . Air resistance and so on..
