2. A band brake uses a V-belt. The pitch diameter of the V-grooved sheave is 20 in. The groove angle is 38° and the coefficient of friction is 0.25. For the dimensions shown in the figure, determine the maximum horsepower rating for 300 rpm. Find also the normal force acting on the band and the bearing pressure per unit width of the band. Estimate the heat generated during braking. 20" V-belt 30 16 N 20" 30"
