The width of the simple band brake shown in the figure is 30 mm. The coefficient of friction between the brake and the drum surface is 0.20. Determine the braking torque and thickness of the band if the tensile stress is not to exceed 65 N/mm2.
How much horsepower is delivered by a block brake having a drum 120 mm in diameter and a 400 mm brake arm length. The pivot point is 40 mm below the point of tangency and 80mm horizontally between the drum and the shoe. The applied load for clockwise rotation is 24,767N when the drum rotates at 300 rpm. Assume a coefficient of friction of 0.25.

Q1/ Figure shows a single block brake applied to a drum by a lever AB which is pivoted at a fixed point A. The radius of the drum is 160 mm. The coefficient of friction at the brake lining is 0.3 and the angle of contact is 40°. If the drum rotates anticlockwise, find the braking torque due to the applied force of 600 N at B. 14-200-> mm 600 N
