The Dzhanibekov effect
HTML-код
- Опубликовано: 11 янв 2025
- The Dzhanibekov effect is a clear demonstration of Poinsot’s theorem on the instability of rotation around an axis with an average moment of inertia. This effect is especially good to observe in zero gravity, but we do experiments that demonstrate and explain this effect in terrestrial conditions.
Key words: moment of inertia, inertia tensor, mean axis theorem.

My hunch is that the apparatus used to hold the model in orientation and in rotation causes extra losses in the center bearing due to the twisting force applied to it by gravity and inertia of the swinging arm. In orbit, no apparatus is required and it is in free fall, the model is free of external torques which limits inertial losses to air resistance so the oscillations are less damped..
Sir I am amazed to see your demonstration and explanation about the effect. I can certainly sayy it was better than Veritasium and provides a greater insight with that handy model👌👌
Also, I think due the acceleration of gravity we ourselves become an obser in non inertial fram due to which a force of gravity is also added which abruptly affects the amplitude of oscillation of the joint masses .
🙏🙏❤
Thanks for the interesting video!
Thanks for watching
Great AI translation of original video. Would be nice to mention a link to the source.
Polarization mean (due to unbalanced weight). Inclined (angle changed) in gyroscope.
Charging and discharging electric.
That model is awesome
So, theoretically, if the rotating axis is exactly the same as the middle axis (without deviation) , the the box rotation will be stable, right?
I THINK youre right
This is what I’m wondering what is the exception?
Holy Prophet ﷺ is reported to have said : When comes the last among the signs of the Qiyamah (armageddon) and the sun will rise from the West instead of the East seeing which the disbelievers of the whole world will start saying that they now believe. All those who had been disobedient will turn into the obedient ones. But, at that time, no believing and no repenting will remain worth accepting. (Al-Baghawi on authority from Sayyidna Abu Hurairah ؓ .
Where did you get the wingnut clip ( it looks like the original Soviet but backwards) ? And dimmer
Thanks much. Some of your colors are indistinct) blue and green)
My dear knight in service of knowledge, I dare to suggest that it might be the transfer of angular momentum of the precession to that of the earth that dampens the precessory mode's amplitude.
My inspection of the gyration provokes the idea that you may have invoked a momentary slowing of the Milankovic Cycle with this formidable apparatus.
With spin, charge, with charge angular momentum?
Why do we see the moment of stability between the flipping of rotation axis? What makes it at one time stable and a second after "unstable"? And why do we see this pause under microgravity conditions?
I think that our understanding of gravity is incomplete. We fail to describe the interaction between the gravity forces of a body and its rotation - with regards to other bodies.
I believe the relation between gravity forces and rotation are very similar to those between magnetic forces and electricity.
Just as movement or rotation of a magnetic body generates electric current within a nearby object, known as Eddy currents, which, in turn, create forces which work against the rotation or movement of the magnetic body, I believe that gravity and rotation behave just like this: the rotation of a heavy body generates a gravitational field which, in interaction with a close and heavier body (the spaceship) generates a force which works on the edges with less momentum of the body, causing them to start rotating in a surface vertical to that of the main rotation.
I believe that gravity force generates rotation of the bodies, and that the rotation decreases the impact of gravity; much like electrostatic tension pulls negatively charged bodies closer, thus decreasing the tension.
Most excellent
Would it be possible to reproduce these experiments in zero gravity, in a simulator?
Yes, of course!
Good sir I believe this is sorcery
Awesome
Can you write equations of motion?
You are asking the impossible, only God can do that.
I feel like it has something to do with angular momentum and the wheels spinning
Ps I skipped the math but your wooden frame was great!
Can the Dzhanibekov effect also happen to the Earth and if it did so, what would the impact of that be?
Let us reassure you: it cannot happen

THANK YOU SO MUCH for showing original wing nut video!!!! I HATE the fcking T handle videos ( sorry not sorry I didn't know you had T handle too)I wish I knew if English is Dzanibekhov or Dzanibekov
Poleshift. The moon pulls on earth. So expect crazy events
It's just gyroscopic stabilization that temporarily destabilizes and then re-stabilizes.
Just

@@getaclass_physics for a moment i thought i was going crazy, there are some weird AI artefacts but the video didnt seem AI generated, knowing now that its a real video that was translated with AI makes much more sense
