    1. I believe the normal force on B is not zero, it is equal to the i-component of the force imparted by rod AB but in the opposite direction. But since B moves vertically along a smooth rod this force should not really affect anything.

      1. If you include the rigid bars holding A and B in the system then you shouldn't have to care about either the normal force or the tension force when solving for omega

  1. How do we find the speed of B after getting the omega at theta=90? Since B is on the same axis as O it wouldn't contribute to the angular momentum I think
