The figure shows an internal rim-type brake having an inside rim diameter of 11 in and a dimension R of 3.5 in. The shoes have a face width of 1.25 in. Find the braking torque and the maximum pressure for each shoe if the actuating force is 205 Ibf, the drum rotation is counterclockwise, and f= 0.32.
