Question

How is the mechanical advantage (MA) related to the velocity ratio (VR) for an ideal machine?



Correct Answer
A

M.A = V.R

Your Answer
B

M.A > V.R

Your Answer
C

M.A < V.R

Your Answer
D

M.A = 2 x V.R


Solution

The correct option is A

M.A = V.R


Ideal machine is free from friction and its efficiency is 100%. For an ideal machine, the efficiency is always equal to 1 and the mechanical advantage is numerically equal to the velocity ratio.
