Question: A body of weight W is required to move up on rough inclined plane whose angle of inclination with the horizontal is ?. The effort applied parallel to the plane is given by(where ? = tan? = Coefficient of friction between the plane and the body.)
Options
A : P = W tan?
B : P = W tan(? + ?)
C : P = W (sin? + ?cos?)
D : P = W (cos? + ?sin?)
