The drum for the band brake in Prob. 16€“11 is 12 in diameter. The band selected has a mean coefficient of friction of 0.28 and a width of 3.25 in. It can safely support a tension of 1.8 kip. If the angle of wrap is 270—¦, find the lining pressure and the torque capacity.
In Prob. 16€“11, The maximum band interface pressure on the brake shown in the figure is 620 kPa. Use a 350 mm diameter drum, a band width of 25 mm, a coefficient of friction of 0.30, and an angle-of-wrap of 270—¦.

Find the band tensions and the torquecapacity.
