Q1:

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.)

A P = W tanα

B P = W tan(α + φ)

C P = W (sinα + μcosα)

D P = W (cosα + μsinα)

ANS:C - P = W (sinα + μcosα)
