The figure shows an internal-expanding rim type brake with an inside rim diameter of 260mm, R 110mm and p = 0.4. The shoes have a maximum pressure of 1MPa and are both actuated by a force of 1200N. For a rotation of clockwise and anti clockwise direction: (a) Determine the shoe width. (b) Calculate the braking capacity. (c) Calculate the hinge-pin reactions. (d) Size the return spring if the closing load for the cylinder is 100N. 349 Pin 30 (12) (8) (8) (16)
