The nominal diameter of a triple- threaded square screw is 50 mm, while the pitch is 8 mm. It is used with a collar having an outer diameter of 100 mm and inner diameter as 65 mm. The coefficient of friction at the thread surface as well as at the collar surface can be taken as 0.15. The screw is used to raise a load of 15 kN. Using the uniform wear theory for collar friction, (1) torque required to raise the load: (ii) torque required to lower the load; and (iii) the force required to raise the load, if applied at a radius of 500 mm.
