Question

How is the mechanical advantage related to the velocity ratio fro (i) an ideal machine, (ii) a pratical machine ?

Open in App
Solution

The mechanical advantage for an actual machine is equal to the product of its efficiency and velocity ratio
M A equals V R cross times eta
(i) an ideal machine efficiency is 1
MA=VR

(ii) a pratical machine
The efficiency of such a machine is always less than 1, i.e. h<1. This is because there is always some loss in energy in form of friction etc
MA<VR
