Figure 1 shows the preliminary design (dimensions in [mm]) of adrum brake system with internal shoes. The maximum contact pressureof the friction material must not exceed the value of 1 [MPa], witha coefficient of friction reported by the manufacturer of 0.34. Thebrake capacity or braking torque shall be 600 [N-m]. It isrequested to complete the design of the brake considering arotation of the drum in the clockwise direction, equal drivingforce in both shoes and equal width of the same.
Calculate the maximum pressures in each shoe, the width of theshoes and the driving force
