Question

1. 16-1. An internal rim-type brake with an inside rim diameter of 300-mm and a dimension R = 125 mm is shown. The shoes have a face width of 40 mm and are both actuated by a force of 2.2 kN. The drum rotates clockwise. The mean coefficient of friction is 028. a) Find the maximum pressure and indicate the shoe on which it occurs. b) Estimate the braking torque effected by each shoe, and find the total braking torque. c) Estimate the resulting hinge-pin reactions.

Step 1

To find the maximum pressure, we need to calculate the force exerted by each shoe on the drum. Since both shoes are actuated by a force of 2.2 kN, the total force exerted by both shoes is 2.2 kN + 2.2 kN = 4.4 kN. The maximum pressure occurs when the force is Show more…
