| 5. | 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) | |
