Suppose I have a circular metal disk spinning at a constant angular velocity. Now imagine near to, but not in contact with the first disk, I have an identical metal disk spinning at the same angular velocity but in the opposite direction (ie. W1 = -w2) and the surfaces are parallel to one another. What is the total angular momentum?
