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

Engineering Mechanics The law of the machine is (where P = Effort applied to lift the load, m = A constant which is equal to the slope of the line, W = Load lifted, and C = Another constant which represents the machine friction.) P = C - mW P = mW - C P = m/W + C P = mW + C P = C - mW P = mW - C P = m/W + C P = mW + C ANSWER DOWNLOAD EXAMIANS APP
