A cylinder is rotating in clockwise direction. It is to be stopped by a band brake (also known as ,,belt brake"). The belt is wrapped around the cylinder (radius r = 0.2 m) and is strained by a lever (L F = 250 N. The coefficient of kinetic friction between the cylinder and the belt is μ = 0.3. Determine the brake torque! H wwwwwwww = 1.2 m) which is loaded by a force
