The slender steel rod AB weighs 6.20 lb and is secured to the rotating shaft by the rod OG and its fittings at O and G. The angle β remains constant at 30°, and the entire rigid assembly rotates about the z-axis at the steady rate N = 600 rev/min. Calculate the angular momentum H_O of AB and its kinetic energy T.
