A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is $$\alpha $$. The effort applied parallel to the plane is given by (where $$\mu $$ = $$ an \varphi $$ = Coefficient of friction between the plane and the body)

Question

A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is $$\alpha $$. The effort applied parallel to the plane is given by (where $$\mu $$ = $$	an \varphi $$ = Coefficient of friction between the plane and the body)

Accepted Answer

P=W(sinα+μcosα)
