How the angular momentum vector is affected by torque, and why this results in gyroscopic precession and for the operation of gyroscopes used for navigation.

Felecity Rex, I appreciate the offer, but no, I do not presently have a donations page. If you want to help out, the best way to do this is simply by sharing my videos, and encouraging people to subscribe to my channel. But thanks for the offer.
OK, I just created a Patreon account, and added the link to it on my RU-vid home page. I don't ask my fans to donate money, but I really do appreciate the fact that some people want to do this, and now I will be able to actually accept. Thanks.
Really clear explanation. Thanks as always, Eugene. I'm just gonna say it - you are simply the best physics teacher on RU-vid. I dare anyone to prove me wrong. ;)
Спасибо за Ваши видео уроки и старания! Эти уроки идеально подходят для развития интуиции при изучении нового предмета и особенно полезны при преподавании студентам.
In case, you have not already seen them, I also uploaded several other videos recently. As always, for each video that you like, you can help more people find it in their RU-vid search engine by clicking the like button, and writing a comment. Lots more videos are coming very soon. Thanks.
I got Poser 3, now twenty years ago! It would produce models for export (which I fed to POV) but was not itself an imaging tool or worked with general shapes like Blender etc.
"Angular momentum definition, the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis." --elinformativo .us Sounds to me like angular momentum is from the moving material inward toward the axis, not from the axis upward as shown.
Best explanation that I've seen yet on this topic. So helpful that you started with forces that act tangentially to the plane of rotation, and THEN you went on to forces that act perpendicular to that plane. Makes so much sense. Thank you so much.

I hate to be the bearer of bad news, but gyroscopic precession never occurs when the floor is removed, or the table to set the gyro on, or a pedestal to put a gyro on top of. When none of that is present...the gyro just levels out and stays perfectly still. But you guys know this right? Precession only occurs when the entire weight of the gyro is resting on a table or the floor or a precious pedestal, acting as a fulcrum point/pivot point for the Precession to begin happening. The BOTTOM of the Gyro has to remain STATIONARY, having all of it's WEIGHT on the SURFACE of a TABLE or FLOOR or PEDESTAL for Gyroscopic Precession to even have a PLACE to happen. Wow yall missed that one by a long shot. It went right on by you, it's was right in front of your faces the whole time. Precession doesn't occur without a stationary pivot point at the bottom.
But, when the girl push a little bit, then angular momentum will have later a different direction and the angular momentum increase so the ring increase the speed and the ring it had more moving energy . And force *distant=energy but the finger doesn't move so we only have the force (the same as the gravity).where does the force come from?????????
I do not understand why do you complicate so much explanation. It is a simple cross product of resulting vectors. The angular momentum is a perpendicular force, resulting from the interacting forces on the ring. When you apply a force, the resulting vector will always be a force in a perpendicular plane to the previous to considered forces. Gyromechanics 101.
I've been wondering what was the physics explanation behind the chasing of the torque by the angular momentum vector. You've just give me the answer. Brilliant, as usual, thank you professor Khutoryansky.
El mejor canal para entender los conceptos naturales y fisicos de la materia el tiempo, espacio y energia. Lo unico que faltaria es que todos los videos esten subtitulados en castelleno.
Thank you, I understand it now. I watched several other videos on it and it made some sense, but this clarified everything the most. 10/10. Love all your videos
Thanks. Always been wondering how these things work. The fact that everything is explained slowly and one by one makes it so much easier to understand.
When reading about this for flying (to understand how several of the instruments work), precession was the one thing in the instruments section I couldn't quite visualise, and this video was incredibly helpful in making it make sense.
Thanks for this video, I really mean it. I've always had this concern about gyroscopes and torque since I was a child. It's the first time I heard someone explain it so well. Totally suscribed.
My father is a civiil engineer. He has been following the gyroscope on avionic application. He found it in your excellent video. He thanks you soo much..
4:12 gave me an eureka moment of finally understanding gyroscopes intuitively for the first time. It's really all about the change of linear momentum of the atoms within the object, as they drag each-other along with their chemical bonds.
I can't believe. Gyroscope is also explain that way. I don't understand gyroscope couple since 4 year. But today I am very excited 😸 after watching this video.lots of thanks.this video is amazing for understanding the gyroscope couple.thanks again
Another masterpiece, Dr. K! I would love to see one on the gyrocompass, and how it needs to be aligned with the earth’s axis. Maybe also one on the ring laser gyroscope?
holy moly.. I knew the torque explanation, but looking for another way to explain it. and I love how you explain it with the motion and inertia at 4:50. It makes a lot more sense for non-science person
A far better explanation then half a dozen other videos I found before this. You have a great gift for explaining such concepts in a way people understand. What software do you use to make the 3D graphics and animation?
Great job! This was really helpful. Question though: You say the direction of the angular momentum vector indicated the axis of rotation. Isn't this only true of angular velocity is about a principal axes? If there are products of inertia, angular momentum doesn't have to be parallel with angular velocity, right? Correct me if I'm wrong. Again, thanks for the great animation.
