Rotation around the axes with the largest and smallest moments of inertia is stable, and the intermediate one is unstable, AKA the 'tennis racket theorem,' which this simulation showed really well, though Rhett could maybe point out that result
No, there's some theorem (can't remember the name - I will look it up) that says the middle eigenvalue axis is unstable. That's why when you toss a block in the air, you can get it to rotate around two of the axes, but not the third.
Am REALLY liking this series. Each step adds more detail. Question: Shouldn't all the principal axes always be stable? That part puzzles me.

@@DotPhysics intermediate axis theorem .
@@DotPhysics ...the tennis racket theorem (see above, lol) :)
@@DotPhysics 👍 Thanks. Oh ok. I wasn't aware of that. I can look through what I have too.
Your effort is awesome 🎉🎉
Glad you like it - this last one was fun (at least for me).
