Спасибо за Ваши видео уроки и старания! Эти уроки идеально подходят для развития интуиции при изучении нового предмета и особенно полезны при преподавании студентам.
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..
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 TH-cam 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.
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.
This video was very informative and I really loved it. I use what’s called the right hand rule. Cuff your fingers around like you are giving a thumbs up. The fingers point in the direction of rotation and the thumb is always pointing in the direction of either angular momentum or torque depending on which force you are applying this rule. Then once you apply the right hand rule, it’s just a matter of remembering that the angular momentum vector always tends towards the torque vector. There, you have it a simplified way of finding the direction of gyroscopic procession.
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.
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'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.

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
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
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.
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
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?
I love this presentation. Question: as a side force is applied (red arrow) and the angular momentum moves out the length of the red arrow, the angular momentum vector becomes longer. Does this suggest the object starts to rotate faster as the green arrow grows?

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.
When you mention that the axis of rotation always points in the same direction as the angular momentum, I believe it would be more accurate to say that they are usually in the same direction but not always exactly. Intermediate axis theorem (or the less technical name for it, tennis racket theorem) and the nutation of a top are direct results of this inconsistency. Otherwise I think this was great video for beginners and I honestly came out with a better conceptual understanding of gyroscopic behavior under the influence of a torque.
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?
4:55 I don’t understand this bit. Please help. Why does the ring move like that? The 2 points seem to move in a different direction to the way the force is pointing
Great Video, but I still have some second thoughts. Is the force from torque causing gyroscope to increase or decrease its angular momentum? Green vector is stretched out when external force is applied in the beginning of this video.
So, gyroscopic momentum induces a precessional torque 90 degrees from an applied torque. Can it be reversed? Specifically, can a combination of applied torques induce a change in the momentum of the gyro? I'm more interested in an increase of rotational velocity, but for the sake of understanding, consider this example: You have a classic spinning gyro suspended horizontally on a string and gravity will induce a precessional torque that will try to make the entire gyro revolve around the string. If you don't allow the gyro to revolve in the direction the precession is trying to make it revolve, will that affect the speed of the gyro? I suspect it will slow down much faster than if it's allowed to precess. Is my suspicion correct?
Awesome video man, but I am actually confused: I don't think angular momentum is ALWAYS parallel to the axis of rotation. It may have another component that makes the total angular momentum arrow go along another direction rather than the one of the axis. Where am I mistaken?
Generally speaking the direction of L is not parallel to the direction of rotation...hence the need for an inertial tensor. But in special cases when rotation is parallel to one of the principle axes -like a gyroscope ...then the angular velocity and momentum vectors are parallel.
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.
Torque represents how quickly the angular momentum is changing. The units for how quickly the angular momentum is chaninging is (N m s) per second, or just (N m.)
I have a question, please reply. (around 8. min) when angular momentum is very big compared to torque created by gravity, the rotating object leans just a little. But this gravity always applies this torque every instant, so my understanding is that it doesn't matter how small it is, it will accumulate very fast. So my question is how can a gyroscope stay put for such long time, doesn't gravity act every instant ?
I always thought that the arrow to indicate torque or angular momentum along the axis of rotation was a notational. I question if doing this was an abuse of notation?
Why does the imagined "angular momentum" have that particular handedness direction in relation to the direction of the spin, instead of a handedness in the opposite direction, (i.e. 180 degrees in the opposite direction) ? And would it be in the opposite direction if the gyroscope was made of antimatter ?
It is just a convention as to what direction we want the arrows to point. If we reversed the directions of all the angular momentum and torque arrows in relation to the spin, all the observable measurements would still be the same.
At 4 minutes, wouldnt it be correct for the F-Vektor to stay vertical as a gravitational force inducing the torque? The way presented in the video there would be a torque and a tranlational movent parallel to the Vektor of the torque. or did i get something wrong?
+ulrike lind, at four minutes into the video, I am not showing the force from gravity, but simply an arbitrary force that someone applies to the object, and then showing how object will react to it. Thanks.

Otherwise I think this was great video for beginners and I honestly came out with a better conceptual understanding of gyroscopic behavior under the influence of a torque.
David Gronlund the axis would constantly be changing, and the arrow would be changed to fit this axis.

How do you explain precession by the mysterious right hand rule when it spins in clockwise?
angular momentum (N m s) and torque (N m) has different units, how did we add those vectors?
Torque represents how quickly the angular momentum is changing. The units for how quickly the angular momentum is chaninging is (N m s) per second, or just (N m.)
Thank you for posting this, very helpful info!
Glad my video was helpful. Thanks.
Could we add two different physical quantities through vector addition
I have a question, please reply. (around 8. min) when angular momentum is very big compared to torque created by gravity, the rotating object leans just a little. But this gravity always applies this torque every instant, so my understanding is that it doesn't matter how small it is, it will accumulate very fast. So my question is how can a gyroscope stay put for such long time, doesn't gravity act every instant ?
Excellant demonstration. GOD bless.
Thanks!
does the radius of the precession circle increases or decreases overtime, as the rotation speed of the gyroscope disk decreases?
as always you are the best
Thanks.
I always thought that the arrow to indicate torque or angular momentum along the axis of rotation was a notational. I question if doing this was an abuse of notation?
Wish I could like this video 100x times.
I am glad that you like my video that much. Thanks.
