What is the relationship mechanical advantage (MA) velocity Ratio (V.R) and efficiency with percentage?
e = M.A/V.R × 100 %
M.A = E.V.R
V.R = 1 ÷ sin θ M.A
M.A = 1/E × 100%
Explanation
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
e = M.A/V.R × 100 %
i.e E/100 = M.A/V.R
= L ÷ E/x ÷ y = Ly/Ex
E/100 = Ly/Ex
