the axis that absorbs a lot of energy is only that B, instead the axis of rotation A absorbs very little energy enough to counteract the internal frictions.

First you have to study the gyroscopic effect and then we can talk.

Now you don't know things, so we can't talk.

I know how a gyroscope works. You just confuse the forces.
An easy experiment:


Make a pendulum that have a fixed direction with firm bearings. Lets say that these bearings is axis B - horizontally. At the bottom of the pendulum you place a flywheel horizontally. That is axis A - vertically. Spin it up, and start the pendulum. Will the pendulum resist moving, or will it not?
The correct answer is: The pendulum works just as a pendulum. Axis B is not restricted. The rotating flywheel have no impact on the pendulum behaviour. Just test it. Easy experiment. I can prove it for you if you want. I got just what I need to show you

iif you can let me see, even a bicycle wheel is fine.

I have an iron flywheel. I spin it up with a Dremel. The attached image shows something similar to what I will make to prove that the pendulum will not just stay one place regardless of position, but swing back and forth without effort even if the flywheel spins at high RPM.

You should make the pendulum always fall from the same height.
First time without the flywheel turning, the second time with the flywheel turning fast.

Because of the frictions, sooner or later the pendulum will stop, if the number of oscillations is equal in both cases, then I am a charlatan otherwise I am a good prophet deserving of applause.
