A flat belt connects pulley A to pulley B. The coefficients of friction are μs = 0.25 and μk = 0.20 between both pulleys and the belt. Knowing that the maximum allowable tension in the belt is 4 kN, determine the largest torque which can be exerted by the belt on pulley A. The radius of the bigger pulley A is R = 203 mm and the radius of the smaller pulley B is r = 25.4 mm. Calculate the resulting bearing force in A.
