Two rotating rods in the vertical plane are connected by a slider block Pof negligible mass. The rod attached at A has a weight of 2.6 lb and a length of 8 in. Rod BP weighs 3 lb and is 10 in. long and the friction between block Pand AE is negligible. The motion of the system is controlled by a couple M applied to rod BP. Know that rod BP has a constant angular velocity of 20 rad/s clockwise. 30 P E Determine the couple M.
