Answer:
The magnitude of effort P(0) requitred to lift the load would then be given by the expression, P(0) = W tan alpha Therefore efficiency = Ideal effort divided by actual effort = P(0) / P Therefore efficiency nu = W tan alpha divided by W tan (alpha plus phi) = tan alpha / tan (alpha + phi) The above final expression ...
