*How are the different spring motions actually coupled in the Wilberforce pendulum?* In the Wilberforce pendulum, the linear tension of the spring (the linear spring constant) is altered by the twisting of the spring, and the rotary spring constant is altered by the linear stretching of the spring. That is why this Wilberforce effect only works with a coiled spring. If you pick out a short portion of the spring wire and examine it very closely you will find that all of the actions involve slightly stretching that part of the wire. But one of the stretches is across the diameter of the wire while the other stretch is along the length of the wire. If you could look really closely, at the atomic level, you would see that all of the actions involve simply stretching the electron shells very slightly. Basically, stretching is stretching, regardless of the direction. Note that if you try to use something like a leaf spring you will not get this Wilberforce effect, though you might get a different effect.

Yeah but you need to be a bit more mature before the fire properly ignites in you so don't feel bad. Feel good that the fire has been lit! Schools should teach you how to think, not just a syllabus. That's help...
5:54 what you showed is not the 3rd normal mode. This is a linear combination of the 1st and 3rd. In the 3rd mode you need the left and right pendulums to move in the opposite direction of the middle one so that the center of mass doesn't move. This is necessary since the 3 modes have to be independant. That's what lets you describe every possible state as a linear combination of these eigenvectors (the normal modes).
You're videos are getting so good man! My only criticism would be setting up those coupled pendulums better 😂(make the sticks the same length and connect the spring straight). Seeing such pure classical mechanics makes me want to review Lagrangian and Hamiltonian mechanics.
This video almost unlocks the secrets of the pendulum in a guitarists right hand. You can set your up and down wrist movement to play eighth notes and transfer that energy into 16 notes using the rotational axis perpendicular to it. I would love for you to make a video on how this works! I will be more than happy to answer questions on this! It is a fascinating application especially for music nerds like me!
This experiment is interesting. In studying physics and chemistry, experiments plays the important roles. But doing experiments are not easy things to do for various reasons for lay persons. You do good jobs by doing these scientific experiments in place of people who can't do them by themselves. I really appreciate your videos. Thanks a lot.
Best intuition ever on quantum state superposition, and also on annoying mechanical resonances on machines.... For example a rotating machine exciting a resonance on a support structure... Etc... If you don't mind I'll use it in the class...
Well, this was quite new to me, I didn't know that this rotational/linear demonstration existed, and much less that it would behave that way. Really interesting stuff.
Surely the Wilberforce pendulum only works because of the spring winding and unwinding. Would this work if you used an elastic band? I don't think it would, because there is no torsional effect transferred between the two.
Here is how I think an elastic band would work because it is linear it can wrap around itself if it has enough tension with weight then you have the torque and up down and left and right linear motion but this is a theory and not practical unless someone proves it and science is about testing theories to see what works and what doesn’t work or different ways how things work and failure is a learning process to find out what works.
@@madatu Theoretical Knowledge Mainly Focuses On Understanding The Concepts And Letting The Person Know What He Should Do And What Steps He Should Follow. Practical Knowledge Focuses On Making The Person Understand How He Should Do It. Simply don’t judge a theory till it has been tried out and made practical. If you don’t know if something might work or might not work it starts with theory when you execute what you want to work to make sure it works or doesn’t work that is practical practice. Springs have tension while under load with something heavy same concept goes with rubber bands the thickness of a rubber band needs more weight to support the tension as well as quantity of thin rubber bands the thinner the rubber band it will break under heavy loads otherwise lower the weight for the rubber band to support a weight or have more thinner rubber bands to support heavier weight to give it tension. That is theory that needs to be tested in order to see what will happen otherwise reject all theories and never see what works and how they work. Just take your time reading all of this to get an understanding on how theory and practical works otherwise someone else needs to explain how theories and practical works.
I’m just sharing more information along with more theories. A torsional pendulum consists of a rigid body suspended by a light wire or spring (Figure). When the body is twisted some small maximum angle (Θ) and released from rest, the body oscillates between (θ=+Θ) and (θ=−Θ) . The restoring torque is supplied by the shearing of the string or wire. This might need to be tested on a number of rubber bands if it doesn’t work then it is just for springs or wires if it does work on a number of rubber bands then it has been proven to work.
Great - worth mentioning that the difference in the two frequencies of motion gives a beat frequency which is the frequency that the WP oscillates between each type of oscillation. Getting the two very close makes for a long 'change over time' which makes this pendulum such fun to watch.
@The Action Lab Could you show more of the details of the spinning coupled pendulum? How is it affecting the angular motion of the weight? Is the string only connected to the tip of the weight, or is it wrapped around, allowing it to spin it back and forth?

In a science place where I worked (it was a science demonstrations to the public (with entry fee) most of the things they could touch and play with (there where signs explaining) But some of the demonstrations needed a guide (which I was) one of them, was a coupled swing which was really cool and it acts just like this, when one is stronger the other one gets weaker
Yes, because twisting a spring will make it contract/expand depending on the direction of twist, so it will start wobbling and then increase the amplitude. Like Crowe3717 mentioned, if the frequencies match then it will be more efficient at transferring the rotational energy to wobble. However, it will be rather tricky to show at the same amplitude as in the video. If you notice, the speed of rotation has to be very high to store the same amount of energy as just a 0.5m of spring expansion. So to have a similar amplitude you would need to somehow give it a spin of that angular speed. I would do that by having a long thin stick pointing downwards from the mass, and I would give it a twist by pressing it between my palms while quickly moving them along each other in opposite directions, like that propeller toy you might have seen.
I'm gonna say no. In this video, he skipped over the reason WHY the stretching of the spring is coupled with the spinning of the weight. I think it is because a spring has to twist somewhat when it stretches or contracts (opposite twist direction, respectively). So what I'm saying is that's what allows the bouncing of the spring and the spinning of the weight to influence each other. I don't see how swinging of the pendulum and the spinning of the weight could be linked. Edit: maybe it would be partially possible. But I think you would have to give an initial push to start the swinging. No way it would start swinging just from spinning (if the spinning is ideally balanced)
What did you mean by "back and forth"? U Lysses answered your question as if you meant "up and down". I answered your question as if you meant swinging back and forth. Your wording is unclear.
You saying “The resonant frequency of the translation oscillation” is so going to be my ringtone. Wish you were my physics teacher at school. Great channel by a great educator.
What makes this work is that when the string lengthens, it unwinds slightly. When it shortens, it tightens slightly. This is how the two motions are coupled. en.wikipedia.org/wiki/Wilberforce_pendulum
Question: Does this imply that moving a detector closer to the sun would yield a higher count of electron neutrinos?... or perhaps they instantaneously begin oscillating to their Muon and Tau forms and there will always be a lower count. I can appreciate this idea of superposition being coupled oscillation. Thanks for the visual demonstration. Well done!
What is the resonate frequency of an ass with specific mass. What if you shake one cheek, will it stop and translate shaking to the other cheek. What if you combine vertical and horizontal shaking. Is it a superposition of add another external force onto the cheeks such as my horizontal or vertical movements
It works because a regular coil spring is actually a torsion spring. Which means that when you stretch or compress a coil spring, you're actually twisting or untwisting it, and that leads the end that's attached to the weight to apply rotational forces as the weight and spring move up and down, making the wight turn. This also means that as the weight spins it coils the spring tighter or less tight, causing the spring to want to rise or fall, which all contributes to the interesting movements we're seeing here.
A view only gets counted after a certain point in the video. If someone likes or comments, and then clicks off the video before that point, then you get odd stats like that.
There is a book titled, Stalking the Wild Pendulum by Itzak Bentov, which has been called an original introduction to quantum mechanics. Bentov suggests that pendulums swinging side by side, as with grandfather clocks, will fall into synch because of resonance, or that Nature supports resonating systems. It is a great read.
1) atoms are smaller than the wavelengths of visible light we can detect, so they cannot even in theory be viewed with visible light. That's why electron microscope exist. 2) The resolving power of the human eye is much too low to make it distinct objects the size of atoms, so even if it were possible to see atoms with visible light our eyes aren't sensitive enough to resolve objects that small.
@@SirPhysics ? If you're asking why you can't see your retina cells it's the same reason your cellphone doesn't take a picture of its ccd sensor. If you're asking why you can't see atoms visible light has too long of a wavelength. Or are you asking something else? Electronic chips use far uv light to image the masks during their fabrication. There's a few utubers that have made their own ic chips but their features are huge compared to current devices.
This is absolutely awe-inspiring! I love science and, particularly, physics. Thank you vey much for this vídeo. I’ll check the action Lab for sure! Cheers!

This phenomenon can also be seen when you bunji-jump with your both arms wide open! To prevent this rotational motion while bunji-jumping, they use several elastic materials sandwiched together in the jumping thread so that one elastic's generated rotational motion is nullified by the others!
Yep. And as it builds more energy in the spinning it has less energy in the stretching. Like how the coupled pendulums transfer the energy back and forth.
You can also make a video about a self-stabilising inverted multi-pendulum. That is a pendulum with multiple segments, set up upside down, while the bottom one is attached to a high frequency linear motor. Such pendulum can stabilise itself to be upright and even re-stabilises when poked. The reason why it works is quite difficult to explain but you could be able to :) I've seen it long time ago at some university, but now cannot find the video any more.
I'm an old man, but I still try to learn at least 10 new things every day. The coupled oscillation, in its many forms, was something I had not known until today. The only force that had anything to do with a "Wilbur" or his forces, was the talking horse from a long time ago. 😉 Thanks for being a light in the dark universe.
Hoa! You should have expanded more on the last things you mentioned at the end--the end has a lot to be digested and understood. It would be nice if you expand more on the theme of superposition.
Easy to understand... The spring is a twisted objekt. If you pull it it will turn around and by doing multiple motions it stacks and more and more energy goes into rotation energy. And finally the motion converted nearly fully it goes around the other way.

Yeah but you need to be a bit more mature before the fire properly ignites in you so don't feel bad. Feel good that the fire has been lit! Schools should teach you how to think, not just a syllabus. That's help...
You can learn maths today. Nothing stops you. There are courses online.
Oh how I wish some one explained physics to me in high school... My career would have been very different... 92 was not a good year for the internet
Free courses at that. See khanacademy and other similar ones.

5:54 what you showed is not the 3rd normal mode. This is a linear combination of the 1st and 3rd. In the 3rd mode you need the left and right pendulums to move in the opposite direction of the middle one so that the center of mass doesn't move. This is necessary since the 3 modes have to be independant. That's what lets you describe every possible state as a linear combination of these eigenvectors (the normal modes).
You're videos are getting so good man! My only criticism would be setting up those coupled pendulums better 😂(make the sticks the same length and connect the spring straight). Seeing such pure classical mechanics makes me want to review Lagrangian and Hamiltonian mechanics.
This video almost unlocks the secrets of the pendulum in a guitarists right hand. You can set your up and down wrist movement to play eighth notes and transfer that energy into 16 notes using the rotational axis perpendicular to it. I would love for you to make a video on how this works! I will be more than happy to answer questions on this! It is a fascinating application especially for music nerds like me!

This experiment is interesting.
In studying physics and chemistry, experiments plays the important roles.
But doing experiments are not easy things to do for various reasons for lay persons.
You do good jobs by doing these scientific experiments in place of people who can't do them by themselves.
I really appreciate your videos.
Thanks a lot.

I honestly love this guy. He puts complex quantum mechanics in a way everyone can understand.
Surely the Wilberforce pendulum only works because of the spring winding and unwinding. Would this work if you used an elastic band? I don't think it would, because there is no torsional effect transferred between the two.
Here is how I think an elastic band would work because it is linear it can wrap around itself if it has enough tension with weight then you have the torque and up down and left and right linear motion but this is a theory and not practical unless someone proves it and science is about testing theories to see what works and what doesn’t work or different ways how things work and failure is a learning process to find out what works.
I think this is a trick. It won't work without a coiled spring.
@@madatu Theoretical Knowledge Mainly Focuses On Understanding The Concepts And Letting The Person Know What He Should Do And What Steps He Should Follow. Practical Knowledge Focuses On Making The Person Understand How He Should Do It. Simply don’t judge a theory till it has been tried out and made practical. If you don’t know if something might work or might not work it starts with theory when you execute what you want to work to make sure it works or doesn’t work that is practical practice. Springs have tension while under load with something heavy same concept goes with rubber bands the thickness of a rubber band needs more weight to support the tension as well as quantity of thin rubber bands the thinner the rubber band it will break under heavy loads otherwise lower the weight for the rubber band to support a weight or have more thinner rubber bands to support heavier weight to give it tension. That is theory that needs to be tested in order to see what will happen otherwise reject all theories and never see what works and how they work. Just take your time reading all of this to get an understanding on how theory and practical works otherwise someone else needs to explain how theories and practical works.
I’m just sharing more information along with more theories. A torsional pendulum consists of a rigid body suspended by a light wire or spring (Figure). When the body is twisted some small maximum angle (Θ) and released from rest, the body oscillates between (θ=+Θ) and (θ=−Θ) . The restoring torque is supplied by the shearing of the string or wire. This might need to be tested on a number of rubber bands if it doesn’t work then it is just for springs or wires if it does work on a number of rubber bands then it has been proven to work.
Build one with a elastic
Amazing insight! this is the first time I have had a hands-on understanding of Quantum superposition! well done, Bravo!!!
Gaia TV: "The mysterious quantum superposition!!"
Action Lab: "Nah it's very simple - let me show how it works on these three penduli..."
Great - worth mentioning that the difference in the two frequencies of motion gives a beat frequency which is the frequency that the WP oscillates between each type of oscillation. Getting the two very close makes for a long 'change over time' which makes this pendulum such fun to watch.
@The Action Lab Could you show more of the details of the spinning coupled pendulum? How is it affecting the angular motion of the weight? Is the string only connected to the tip of the weight, or is it wrapped around, allowing it to spin it back and forth?
This is a lovely explanation. Thank you The Action Lab.

In a science place where I worked (it was a science demonstrations to the public (with entry fee) most of the things they could touch and play with (there where signs explaining)
But some of the demonstrations needed a guide (which I was) one of them, was a coupled swing which was really cool and it acts just like this, when one is stronger the other one gets weaker
How does the Wilberforce pendulum behave with a swivel between spring and pendulum weight?
This is a great question
I am guessing that would remove the torsional force of twsiting spring so it would never go to spinning
It requires the spring torsion. It in the equations.
This description was very elegant. Thank You.
So, I have a question. If I rotate the pendulum, it can somehow change its rotation to back and forth?
Assuming both modes of rotation have similar resonant frequencies yes.
Yes, because twisting a spring will make it contract/expand depending on the direction of twist, so it will start wobbling and then increase the amplitude. Like Crowe3717 mentioned, if the frequencies match then it will be more efficient at transferring the rotational energy to wobble.
However, it will be rather tricky to show at the same amplitude as in the video. If you notice, the speed of rotation has to be very high to store the same amount of energy as just a 0.5m of spring expansion. So to have a similar amplitude you would need to somehow give it a spin of that angular speed.
I would do that by having a long thin stick pointing downwards from the mass, and I would give it a twist by pressing it between my palms while quickly moving them along each other in opposite directions, like that propeller toy you might have seen.
I'm gonna say no. In this video, he skipped over the reason WHY the stretching of the spring is coupled with the spinning of the weight. I think it is because a spring has to twist somewhat when it stretches or contracts (opposite twist direction, respectively).
So what I'm saying is that's what allows the bouncing of the spring and the spinning of the weight to influence each other. I don't see how swinging of the pendulum and the spinning of the weight could be linked.
Edit: maybe it would be partially possible. But I think you would have to give an initial push to start the swinging. No way it would start swinging just from spinning (if the spinning is ideally balanced)
What did you mean by "back and forth"? U Lysses answered your question as if you meant "up and down". I answered your question as if you meant swinging back and forth. Your wording is unclear.
@@ewthmatth I meant up and down. Sorry for my unclearness :(

"Super position isn't anything mystical in quantum mechanics"
At least until you're not sure if your cat is dead or alive.
Agree; the mysticism in quantum mechanics sounds a lot like religion.
Best visual representation of superposition I’ve seen 👍🏻
What makes this work is that when the string lengthens, it unwinds slightly. When it shortens, it tightens slightly. This is how the two motions are coupled. en.wikipedia.org/wiki/Wilberforce_pendulum

Question: Does this imply that moving a detector closer to the sun would yield a higher count of electron neutrinos?...
or perhaps they instantaneously begin oscillating to their Muon and Tau forms and there will always be a lower count.
I can appreciate this idea of superposition being coupled oscillation. Thanks for the visual demonstration. Well done!
Twerking the spring!? Oooohhh torque....

What is the resonate frequency of an ass with specific mass. What if you shake one cheek, will it stop and translate shaking to the other cheek. What if you combine vertical and horizontal shaking. Is it a superposition of add another external force onto the cheeks such as my horizontal or vertical movements

Watching During My Lecture Of Newton's Law Of Motion
It works because a regular coil spring is actually a torsion spring. Which means that when you stretch or compress a coil spring, you're actually twisting or untwisting it, and that leads the end that's attached to the weight to apply rotational forces as the weight and spring move up and down, making the wight turn. This also means that as the weight spins it coils the spring tighter or less tight, causing the spring to want to rise or fall, which all contributes to the interesting movements we're seeing here.
Thankyou for saying this,I was thinking the same especially concerning the angular momentum conservation...

This question deserves a video
A view only gets counted after a certain point in the video. If someone likes or comments, and then clicks off the video before that point, then you get odd stats like that.
There is a book titled, Stalking the Wild Pendulum by Itzak Bentov, which has been called an original introduction to quantum mechanics. Bentov suggests that pendulums swinging side by side, as with grandfather clocks, will fall into synch because of resonance, or that Nature supports resonating systems. It is a great read.

Hey Fella I would really like to know about why dont we see atoms in our retina if light creates the image of an object in our eyes?!
1) atoms are smaller than the wavelengths of visible light we can detect, so they cannot even in theory be viewed with visible light. That's why electron microscope exist. 2) The resolving power of the human eye is much too low to make it distinct objects the size of atoms, so even if it were possible to see atoms with visible light our eyes aren't sensitive enough to resolve objects that small.
Simply put they are too small.
@@SirPhysics ? If you're asking why you can't see your retina cells it's the same reason your cellphone doesn't take a picture of its ccd sensor. If you're asking why you can't see atoms visible light has too long of a wavelength. Or are you asking something else? Electronic chips use far uv light to image the masks during their fabrication. There's a few utubers that have made their own ic chips but their features are huge compared to current devices.
That's the best intuitive description of superposition. Thanks!
You probably won't see this comment but isn't this somehow related to that time when the soviets discovered a weird movement of a screw in 0 gravity?

This phenomenon can also be seen when you bunji-jump with your both arms wide open! To prevent this rotational motion while bunji-jumping, they use several elastic materials sandwiched together in the jumping thread so that one elastic's generated rotational motion is nullified by the others!

The spinning is from the coil spring stretch. Check out the Super Two Stage Oscillator.
Yep. And as it builds more energy in the spinning it has less energy in the stretching. Like how the coupled pendulums transfer the energy back and forth.

You can also make a video about a self-stabilising inverted multi-pendulum.
That is a pendulum with multiple segments, set up upside down, while the bottom one is attached to a high frequency linear motor. Such pendulum can stabilise itself to be upright and even re-stabilises when poked. The reason why it works is quite difficult to explain but you could be able to :)
I've seen it long time ago at some university, but now cannot find the video any more.
If it was a linear spring, it would NOT spin. Because of the the coiled spring it causes the spinning. Try it without a coiled spring.
What is a linear spring? Can you explain that first before you start challenging and confusing everyone here?

Easy to understand... The spring is a twisted objekt. If you pull it it will turn around and by doing multiple motions it stacks and more and more energy goes into rotation energy. And finally the motion converted nearly fully it goes around the other way.
