2. A differential band brake similar to that in Fig. 13.19 uses a wowen lining having design values of f=0,24 and pmax=500 kPa. The speed is 300 rpm a= 550 mm c= 160 mm w= 60 mm r= 200 s= 25 mm and 270 deg. Predict the (a) torque capacity (b) actuating force (c) power capacity and the values to cause the braket o be self locking. -Band of width, w Rotation Drum F2 a V M (mass) k
