A flexible belt placed around a rotating drum of 4-inch radius acts as a brake when the arm ABCD is pulled down by the force P. The coefficient of kinetic friction between the belt and the drum is 0.2. Determine the force P that would result in a braking torque of 400-lb : in., assuming that counterclockwise. Neglect the weight of the brake arm. the drum is rotating
