B 29 lb/ in D 20 lb/in 11. A band brake consist of lever attached vertically to one end of the band (band connected midpoint of the lever which is 2m long). The other end of the band is fixed to the ground. The wheel has radius of 200 mm and the wrap angle of the band is 270 deg. The braking force applied to the lever is limited to 100N and the coefficient of friction between the band and wheel is 0.5. A 1200N C 3224N B 2110N D 4420N 12.
