Had a quick search, didn't find anything.
So, we have been told on our course, that a spinning extended object will "re-align" itself such that it is spinning along a principle axis with the highest moment of inertia, such as to conserve angular momentum, but minimise rotational kinetic energy.
By this process, why does a bullet fired from a rifled barrel not "want" to tumble, rather than fly straight and stable?
