A simple band brake is applied to a drum of 560 mm diameter which rotates at 240 r.p.m Angle of contact of the band is 270. Coefficient of friction is 0.3. The power absorbed is 40 kW. 0 140m -800m FINT (a) 62.6 mm (c) 87.4 mm AF 09. The maximum tension in the band is (a) 4792 N (b) 5218 N (c) 6210 N (d) 7502 N 10. If the thickness of band is 3mm and the tensile stress is limited to 40 MPa, then the width of the band is (b) 75.1 mm (d) 92.6 mm
