Find the force required to move a load of 300 N up a rough plane, the force being applied parallel to the plane. The inclination of the plane is such that a force of 60N inclined at 30° to a similar smooth plane would keep the same load in equilibrium. The coefficient of friction is 0.3. 1. [Ans. 146 N] A square threaded screw of mean diameter 25 mm and pitch of thread 6 mm is utilised to lift a weight of 10 kN by a horizontal force applied at the circumference of the screw. Find the magnitude of the [Ans. 966 N] 2. force if the coefficient of friction between the nut and screw is 0.02.
