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 tanα P = W tan (α + φ) P = W (sinα + μcosα) P = W (cosα + μsinα) P = W tanα P = W tan (α + φ) P = W (sinα + μcosα) P = W (cosα + μsinα) ANSWER DOWNLOAD EXAMIANS APP

Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Minimum, if it acts at the center of gravity of the body Different at different points on its line of action Same at every point on its line of action Maximum, if it acts at the center of gravity of the body Minimum, if it acts at the center of gravity of the body Different at different points on its line of action Same at every point on its line of action Maximum, if it acts at the center of gravity of the body ANSWER DOWNLOAD EXAMIANS APP
