The 3-lb uniform slender bar AB is connected to the 6-lb gear B which meshes with the stationary outer gear C. The centroidal radius of gyration of gear B is 1.2 in. The system is released in the position shown when the angular velocity of the bar is 4 rad/s counterclockwise. Knowing that the magnitude of the angular velocity of the bar as it passes through the vertical position is 12rad/s, determine the amount of energy dissipated in friction.
