A differential band brake shown below is being considered for use and requires a brake torque of 4213 Nm to hold the drum from slipping. Available space limits the cast-iron brake drum diameter to 489.8 mm, with brake band contact extending over an angle of 230°. Design values for the brake lining selected are u=0.4, pmax = 1.3 MPa. Start out by determining the difference in P, and P2 in Newtons to one decimal place. F P2 120 650
