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