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

$${\text{P}} = {\text{W}}\tan \alpha $$
$${\text{P}} = {\text{W}}\tan \left( {\alpha + \varphi } \right)$$
$${\text{P}} = {\text{W}}\left( {\sin \alpha + \mu \cos \alpha } \right)$$
$${\text{P}} = {\text{W}}\left( {\cos \alpha + \mu \sin \alpha } \right)$$
