Question

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

• A. M.A = V.R
• B. M.A > V.R
• C. M.A < V.R
• D. M.A = 2 x V.R

Answer 1

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.
