That first 1:30 pretty much explained what I needed, thankyou very much. Every other explanation I found would just say "There is angular momentum" leaving me a little infuriated at the fact that every explanation made that statement without saying where from. Thanks!
tesla said he didnt like the direction the understanding of physics and the universe was going because instead of trying to understand in physical ways you learn from complex equations that are hard to visualize/ conceptualize
Watch the following video to have the turning make sense. Basically, not only does the 180° rotational flip cancel the "torque" or force applied by gravity on the wheel... The force is "moved" 90° by the rotation (or a quarter circle) and while pushing in the same direction it makes the wheel go around. It's actually rediculous how little sense this makes without analysing it. Yet how logical it is in the end.
Tom, according to your explanation, would it not mean that if I rotate the wheel twice as fast as what your example shows, the segment that was rotating left and up would again rotate left and down which would make the wheel fall?
I like the explanations. The problem I have is with some claims that are always made whenever these things are explained. If the gyroscopic effect of not falling, and also precession, is always independent of the speed of rotation, then how is it that if the speed of rotation were 1 revolution per century, and surely indistinguishable from not rotating, the wheel necessarily falls and does not precess. What's more, the wheel looks like it is falling, but slowly, because the axis turns downward gradually. Where does the energy come from that makes the gyroscope precess? Does it come from the spin of the rotor? Does it come from the potential energy of gravity, as the gyroscope progressively turns downward?
By "new flipping axis" they mean the point upon which the gravitational "downward" force" was applied is now 90° or a quarter circle further and instead of moving down it makes the wheel turn around it's point of suspension.
@@demagescod9657 You have got good brains. It is not 90 degrees but 180 degrees. Let's just think this through. A spinning gyroscope must be analysed as if it is in empty space. When you put it on earth, you then have to identify the forces acting on it. Thereafter you apply all known 'discovered' laws of physics and apply them. You will get the answer. All the best.
good video ! but one question: so if the segment which is , when the wheel is not spinning, going up and right (so it flips) spinning so fast that the movement is not down and right but also up and right as if was in the first place, do you get what i'm trying to ask ?
You're trying to ask if it can spin too fast; if the effect can undermine itself. And the answer is no. It's a system with pseudo-binary fundamentals. That is, whatever happens to one "slice," the effects on the opposite "slice" are complimentary and instantaneous. The "speed" of the effect is applied equally to opposite "slices."
Though it is a nice explanation, and suits the maintenance of weight which is preserved whether we are holding the wheel spinning or not, it still does not consider the fact that, as noted in many gyroscope observations, the people trying to hold a heavy steel wheel while it's not turning, find it very difficult to lift it even if lifting is applied somewhere close to the center of gravity of the object; whilst on the other hand, when the wheel is turning they physically seem pretty much able to easily lift the heavy rotating wheel above their heads. I believe there is something more to it than just tipping balance equations. Take for example a rotating wheel which is supported along its radial periphery (not with an extended axis), it will still turn around its base (loose base) depending on the rotation direction though there is no tipping force resulting from its weight.
This is a good explanation but it does not explain why the centrifugal force parallel to the horizontal axis is diminished when the gyro is used as shown in the video. Here is a more detailed explanation. 1. As the center of the wheel tries to drop down the uppermost mass particle is accelerated and swings to the left while the lowermost particle is accelerated in the opposite direction and swings right with the resulting opposite reactions on the wheel. As the wheel is spinning as shown, the closest upgoing mass particle will be swung and thrown to the left and will finish at the far side to the left while the furthest downgoing mass particle will be swung and thrown to the right and will finish at the near side to the right. This continuous action will change the direction of the horizontal diameter which causes the wheel to precess around the suspension point in the direction shown. 2. This continuous acceleration of the mass particles out away from the vertical of the suspension point on the upper half of the spinning disc and the opposite acceleration of the mass particles into the suspension point on the lower half of the spinning disc will in fact act as a machine gun on the upper half of the spinning disc accelerating bullets away from the vertical suspension point and another machine gun on the lower half of the spinning disc accelerating bullets towards the vertical suspension pivot line. The opposite reactions of these two machine guns will create a torque that will keep the wheel in the same plane while at the same time reducing the centrifugal force of the wheel going around the suspension vertical point. In reality, the secret of the torqued gyro lies in the fact that the continuous outwards acceleration of the mass particles on the upper half of the disc creates an INWARD BOUND CENTRIFUGAL FORCE (F1) while the lower half of the spinning disc creates an OUTWARD BOUND CENTRIFUGAL FORCE (F2) related to the conventional outbound centrifugal force we normally assign to a mass rotating around a pivot center. 3. The whole action may be summarised by assuming F1 to be the inward bound centrifugal force on the upper half while F2 is the outbound centrifugal force acting on the lower half, where they have the same vertical and horizontal separation "X" where the torque produced in the vertical and horizontal plane ( F1+F2)*X will balance the torques generated by the gravity torque m.g.Ra and the inertia torque I.Ws.Wp hence m.g. Ra= ( F1+F2)*X = I.Ws.Wp The elegant phenomenon is seen so clearly if one plots the plan view of the cycloidal path the mass particles have to traverse when they spin and rotate around the pivot point. The instantaneous center of curvature of the plan view of the cycloidal trajectory will uncover all the secrets of a precessing gyro. The generation of the outbound centrifugal force (F1) says the whole story.
Sir you said that upper point will have force towards left and bottom one will have towards right,and when their positions will interchange they will maintain the same force and will cause balance.🤔🤔.why will they maintain same force,for this you said that spinning should be fast enough.but being fast also, force is so instantaneous that it will not be maintained.It will disappear when the upper or lower point changes slightly also
How do you calculate how fast the wheel has to spin in order to precess? And how do you calculate the increase in the rate of precession based on the added weight to the wheel's axle? I think this is where the math would come in handy :) Also it would be interesting to hear how all the people who claim to have finally "understood" gyroscopic motion in the comments section below explain it to a friend without referring to your video (which is excellent!).
Heißt dass das Rad nach einer Zeit (ohne Reibung ) sich statt vertikal horizontal sich bewegt weil sich denn die potentielle Energie der rads in die Bewegungsenergie des rads (um das Seil Bewegung)sich umgewandelt hat.
level1807 The flipping axis is at a 90° (horizontal) angle to the vertical gravitational force for symmetrical reasons (the wheel is a symmetrical object and hence the axis has no 'reason' to be tilted towards the right or left compared to the perfect horizontal plane). So now you could ask "why is it exactly the 'flipping axis' which is turning and not another random axis?". Again, the reason is symmetry: for example, if the motion of the flipping axis would be at 120°, it wouldn't turn within the horizontal plane, but instead move slowly upwards and defy gravity. Obviously, it can't do that. It needs to stay in the horizontal plane, which happens to be in a 90° angle to the vertical gravitational vector. I hope that helps. If it is still unclear, let me know!
Okay, thank you. I am a physicist, and I am familiar with the rigorous proof of this fact, but I just wish the video had been a bit more accurate. Even with your explanation, it's still unclear why the axis of the wheel should be moving in the horizontal plane at all: by the video's and yours symmetry considerations, this axis could well stand in one horizontal position (180 is just as good an angle for "fraction of a second movement" and symmetry).
+level1807 Simple because the spinning axis has to remain constant and for that the flipping axis has to be exactly at 90 degrees or else it would defy the concept of stablisation of spinning axis due to mass moment of Inertia....
maybe this helps: the spining wheel segment does not only flip 180° before it exerts a force on the bottom side again ~1:10. It also flips 90° and then applies the force. that way the wheel starts spinning as well as staying veritcally.
More over, with a real gyroscope, turning at a fixed speed, the orientation of the axial deviation is maintained no matter where you are on the planet as if once it's turned it's locked to some OWN fixed magnetic bubble.
I like what you’re doing here, but for my own personal preference I like a little scientific explanation following the simple one. Even if it goes over someone’s head, I feel like that sort of knowledge has a sort of passive compounding effect ¯\_(ツ)_/¯ Once you’ve heard it a bunch of times there’s a better chance it’ll start making more sense. Just a suggestion though, keep up the good work and thank you for increasing the collective knowledge/understanding of humanity
now THAT's a good and simple explanation. I agree with the last phrase.
I don't. How do we know his name is Tom?
WTF! This was so easy. I spent like years trying to get an intuitive understanding about this and now I finally get it. Thank you.

This is enjoyable and understandable. Please do more!

But now I do, and its so simple! Thank you so much!

worth every one of likes
Best explanation I've ever saw about gyroscope! Where can I find the math behind it? Not the traditional, but with the same way you said.
Great way to explain a very important phenomenon, Respect
Thx for the explanation. It is very useful for my gyroscope research.
Thank you Tom,

and u earned something(my subscription)
Fantastic explanation.
thank you Tom
your videos cheer me to live
Thank you so much!
Ok but why are forces turned 90° instead of 60° or any other amount?
Thank you, I now understand this for the first time. RUclips is so much better than university.
Thanks! This has been confusing me for years!
I don’t agree with explanation. There is a axial force acting due to Torque. Which is canceling the flipping force
Do you really understand this? This video explains WHY the torque is higher in the axis of the spin.

Thanks Tom for One more piece of puzzle,
We love you Tom!
No one went through this approach like you did , finally gyroscopic effect is understood. Thanks Buddy (indian accent).
Thank u so much sir,
Sorry, I don't understand why the wheel rotates around the rope. Is it possible for you to explain it in another way? Thanks
it is falling sideways.
Finally the puzzle got solved .
A big thanks to you.
If you would have been my college teacher , I might have been a scientist.

i like tis tipe of teaching. wich school do you teach tom?
This is a good explanation but it does not explain why the centrifugal force parallel to the horizontal axis is diminished when the gyro is used as shown in the video.

Force changes instantaneously, but momentum doesn‘t.
Ultimate explanation...
It seems so simple when you break it down like that..!
Yeah, but no one agrees how a bicycle can stay upright ! 😂
Can anyone explain what happened after the weight is applied??
What about when it spins horizontally?
Thanks man
You speak like CGP Grey. It's nice.
Is it just me, or does this feel a lot like troll physics? I know it isn't, but it feels like it...
lol
HAHAHA OMG (1:43)
This is good content
Holy shit this is mindblowing
Did not understand the 90 deg turn of flipping angle. But first was nicely explained.
How do you calculate how fast the wheel has to spin in order to precess? And how do you calculate the increase in the rate of precession based on the added weight to the wheel's axle? I think this is where the math would come in handy :)
Also it would be interesting to hear how all the people who claim to have finally "understood" gyroscopic motion in the comments section below explain it to a friend without referring to your video (which is excellent!).
Woo! I understood that! More physics please! :D :D :D
This is how teachers explain - even with an accent, one can still learn more!
Heißt dass das Rad nach einer Zeit (ohne Reibung ) sich statt vertikal horizontal sich bewegt weil sich denn die potentielle Energie der rads in die Bewegungsenergie des rads (um das Seil Bewegung)sich umgewandelt hat.
OH MY GOD! (No sarcasm this really changed my life)
So why would that angle (2:20) be exactly 90 degrees? Why not 180 or 17.45?
level1807 The flipping axis is at a 90° (horizontal) angle to the vertical gravitational force for symmetrical reasons (the wheel is a symmetrical object and hence the axis has no 'reason' to be tilted towards the right or left compared to the perfect horizontal plane). So now you could ask "why is it exactly the 'flipping axis' which is turning and not another random axis?". Again, the reason is symmetry: for example, if the motion of the flipping axis would be at 120°, it wouldn't turn within the horizontal plane, but instead move slowly upwards and defy gravity. Obviously, it can't do that. It needs to stay in the horizontal plane, which happens to be in a 90° angle to the vertical gravitational vector.
I hope that helps. If it is still unclear, let me know!
Okay, thank you. I am a physicist, and I am familiar with the rigorous proof of this fact, but I just wish the video had been a bit more accurate.
Even with your explanation, it's still unclear why the axis of the wheel should be moving in the horizontal plane at all: by the video's and yours symmetry considerations, this axis could well stand in one horizontal position (180 is just as good an angle for "fraction of a second movement" and symmetry).
+level1807 Simple because the spinning axis has to remain constant and for that the flipping axis has to be exactly at 90 degrees or else it would defy the concept of stablisation of spinning axis due to mass moment of Inertia....
maybe this helps:
the spining wheel segment does not only flip 180° before it exerts a force on the bottom side again ~1:10.
It also flips 90° and then applies the force. that way the wheel starts spinning as well as staying veritcally.
You are awesome
thank you I doubt my professer know it
Is there any angular momentum, torque etc 😂
Without energy how its possible to avoid flipping?
WOW! Maybe I’m not as dumb as I thought! ;) I get it now

Not true.
make more sense than angular momentum :P

If at 1:28 it was balanced then why not at 2:11??

You are right to be confused.
Dunno, this sure is easy but way too simplified that it makes me think there might be lots of logical jumps in the course of deduction
Nach dem letzten Satz solltest du Bildungsminister werden.
Wow. This is a very nice explanation. I hate formulas which don't sound logical.
