Maximum Mechanical Advantage of a Lifting Machine :
Maximum Mechanical Advantage of a Lifting Machine :
We know that mechanical advantage of a lifting machine
M.A. = W/P
For maximum mechanical advantage, substituting the valve of
P = mW+C in the above equation.
Max. M.A. =
…… (Neglecting C/W)
Maximum Efficiency of a Lifting Machine :
We know that the efficiency of a lifting machine,
For maximum efficiency*, substituting the value of P=mW+C in the above equation.
