The relationship between mechanical advantage (M.A.) and velocity ratio (V.R.) for a practical machine is:
- M.A.= V.R.
- M.A.> V.R.
- M.A.< V.R.
- None of these

Answer
M.A.< V.R.
Reason — In actual practice there is some friction between the parts of the machine or deformation of parts, which causes the mechanical advantage to be less than the velocity ratio.
