>>12971010>that stress, tension and elastic energy are independentthey aren't independent from another. they are independent of the period by which a tennis racket flips. I've already proven this in two posts.
> As the raquet spins, the geometry of the body deforms changing the center of mass and moment of inertiavery, very, very slightly. the effect is totally negligible.
>NO BODY is perfectly rigidplenty of bodies (lots and lots) are approximately rigid and even more bodies are approximately elastic. you realize elasticity is an approximation too, right?
>that the intermediate axis theorem may be derived from small changes to the center of mass building up as the raquet continues to spinthat is not the intermediate axis theorem, that's something different I've never quite heard of before.
