The force of friction will act Away from the wall at its upper end Upward at its upper end Towards the wall at its upper end Downward at its upper end Away from the wall at its upper end Upward at its upper end Towards the wall at its upper end Downward at its upper end ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics 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.) P = W (sinα + μcosα) P = W tan (α + φ) P = W (cosα + μsinα) P = W tanα P = W (sinα + μcosα) P = W tan (α + φ) P = W (cosα + μsinα) P = W tanα ANSWER DOWNLOAD EXAMIANS APP
