3. A 30kg uniform bar is free to rotate without friction about a fixed axis at Point A. W T 1 m a. A 3 m 19 30 kg What is the angular acceleration, a, of the bar when it is horizontal, as shown? b. If the bar was released from rest at this position (w = 0 rad/s), what would be the force that the support is putting on the bar at Point A? c. If the bar already has an angular velocity of w = 4 rad/s at the point shown, what would be the force that the support if putting on the bar at Point A?
