Q12/ The simple band brake shown in figure is applied to a drum of
diameter 240 mm. The drum is rotating at 300 rpm. The angle of
contact of the band on the drum is 210 and u = 0.2. One end of the
100 N
band is attached to a fixed end A and other end to the lever arm at a
distance 120 mm from A. The lever length is 420 mm. Determine
(a) the braking torque and (b) width of steel band if the maximum
tensile stress in the band is not exceed 15 N/mm?. Take thickness of
240
band as 3 mm.
