Question: 20 cm 1 the 06 kg uniform 80cm rigid...

Question details

-20 cm -|-1 . The 0.6 kg uniform 80cm rigid bar is pinned at A. At the instant shown the rigid body has a clockwise angular velocity of 4 rad/s and a counterclockwise angular acceleration of 10 rad/s (a) What is the velocity of the mass center at this instant? (b) What is the acceleration of the mass center at this instant? (c) What is the value of the applied moment at this instant? d) What are the components of the reaction at the support at this instant? (e) What is the kinetic energy of the bar at this instant? (f) What is the angular momentum of the bar about an axis through A at this instant?
