Homework Help: Physics

Posted by James on Wednesday, June 20, 2012 at 1:22pm.

The system shown in the figure is held initially at rest. Calculate the angular acceleration of the system as soon as it is released. You can treat MA (1 kg) and MB (12 kg) as point masses located on either end of the rod of mass MC (27 kg) and length L (9 m). (Indicate the direction with the sign of your answer. Let the counterclockwise direction be positive.)

The answer is 0.934 rad/s^2. I'm not sure how to set this problem up. Any help is appreciated.
