What is the relationship mechanical advantage (MA) velocity Ratio (V.R) and efficiency with percentage?

  • A e = M.A/V.R × 100 %
  • B M.A = E.V.R
  • C V.R = 1 ÷ sin θ M.A
  • D M.A = 1/E × 100%

The correct answer is A. e = M.A/V.R × 100 %

he relationship between M.A, V.R, e and 100% can be written as

e = M.A/V.R × 100 %

i.e E/100 = M.A/V.R

= L ÷ E/x ÷ y = Ly/Ex

E/100 = Ly/Ex
