Ive tried to keep it simple and given a simple way to try it for yourself using two angle grinders. Maybe explaining it like this...

It is a covector, but that does not mean that angular momentum also is.

So why not do the decent thing and correct or delete your erroneous post #8?

You have become Idolaters of syntax and grammar, I'm dealing with priests of the page, not engineers of reality. And as for the Guessing...

You ignored other questions @A.T. asked. Where is the maths?

Yeah, although that would be a pity. The cure might be worse than the poison (in terms of the GD experience.)

In face-to-face communication I would first ask to write down the formula of kinetic energy of a rigid body and then to provide...

What is "steady state", "no motion", and "resulting torques"? Since you have posted a labeled diagram, why don't you use those symbols...

OK, and where is energy "destroyed" here (aside of dissipation by friction)?

That could also mean, that nobody was even able to make sense of what you are talking about.

Your question would be better stated in terms of. "I know that energy isn't destroyed so where have I gone wrong in my reasoning and...

Any time you run into a paradox, your first thought should be that you have taken a wrong turn on the way there. You have started from...

I do not understand what this means. By definition a vector field on a manifold ##M## is a function ##v:M\to TM## such that ##v(x)\in T_xM##

Then stop using sentences that needs to be backed up by references.

for example Hawking and others https://www.thoughtco.com/what-is-model-dependent-realism-2699404 I gets cumbersone to provide a...
