Engineering Mechanics On the ladder resting on the ground and leaning against a smooth vertical wall, the force of friction will be Downwards at its upper end Upwards at its upper end Zero at its upper end Perpendicular to the wall at its upper end Downwards at its upper end Upwards at its upper end Zero at its upper end Perpendicular to the wall at its upper end 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 = mW + C P = mW - C P = C - mW P = m/W + C P = mW + C P = mW - C P = C - mW P = m/W + C ANSWER DOWNLOAD EXAMIANS APP
