Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_135

6/135 The mass center G of the slender bar of mass 0.8 kg and length 0.4 m is falling vertically with a velocity \( v = 2 \text{ m/s} \) at the instant depicted. Calculate the angular momentum \( H_O \) of the bar about point O if the angular velocity of the bar is (a) \( \omega_a = 10 \text{ rad/s} \) clockwise and (b) \( \omega_b = 10 \text{ rad/s} \) counterclockwise.
