A single block brake with a torque 300 200 capacity of 250

A single block brake with a torque 300 200 capacity of 250 Nm is shown in the following figure and the P coefficient of friction is 0.2. Calculate the actuating force P: (a) 50 for clockwise rotation of the drum; (b) for anticlockwise rotation of the drum and (c) the location of the fulcrum to make the brake self-locking for clockwise rotation of the drum. All dimensions R= 250 are in mm.
