  1. A body of weight W is required to move up on rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by(where μ = tanφ = Coefficient of friction between the plane and the body.)

  2. A.

    P = W tanα


    P = W tan(α + φ)


    P = W (sinα + μcosα)


    P = W (cosα + μsinα)
