Lets look at your !big reveal! answers then.
Post 1847.--The wine glass resonates by cycling energy back and forth between two forms, kinetic energy and potential energy.
This part is good.
The instant when the glass is not deformed, the glass is moving at a maximum velocity
This is correct as well
all of the energy is stored as kinetic energy in the form of a moving mass
This is  incorrect,as some of the energy is dissipated while the mass is moving -in simple terms,in way of sound waves.
The instant when the glass is at its maximum deformation, the glass has stopped moving and all of the energy is stored as potential energy in the form of a compressed spring
Well i see at this !instant! point in time,you have correctly stated that the glass has stopped moving-!BUT! not all of the kinetic energy is stored as potential energy,but more so the remaining kinetic energy is stored as potential energy. But at this very point the glass stops moving,is the very point when a vibrational wave is created,and so at the point of kinetic to potential energy transformation,a small portion of energy is dissipated as vibrations.
It is also funny how you have used the term!compressed spring!,where a spring has very little stiffness,but a high value of elasticity--something to think about
In between these two states, the energy is stored as combination of kinetic energy and potential energy.
Not all the energy is stored,as some is dissipated-as i explained above.
Almost MH,but you needed to add in the environmental conditions as well--to be accurate,as the wine glass would also have to include the atmosphere that is both inside and around the wine glass as effective moving mass,along with being an effective resistance as well--none of that in space  --but we wont get picky now.
See,now here is where you went from compressed spring to stiffness. The correct term(and this is the scientific term MH)is elasticity of the glass--not stiffness,as when you use the correct term!elasticity!,then the elasticity value has to decrease in order for the resonant frequency to increase,where as your !!stiffness!! has to increase in order for the resonant frequency to increase

These were your answers MH,and you said that all of ours given were wrong,and yours was going to be absolute,and correct.
If you are going to make a claim like this,then you need to be 100% correct-even in a 4 sentence explanation. But as you can see,you were not,and that is fact MH.
If any one of us had of put up answers like that,after dismissing everyone elses,then you would have picked us apart--as you generally do.
So the same applies to you--you were not 100% correct MH,and all that you have provided had been already stated many times in the thread.

All of your comments about losses are not applicable.  Like I already told you, this is a basic academic approach to understanding what resonance is.  This is analogous to telling to you and others that you can discuss an ideal coil that has no electrical resistance and try to understand how it will function in a circuit.  I think it took you and your peers a couple of years to come around on that one and accept it.  Likewise, this is just a discussion about resonance in a wine glass with the goal of understanding how the resonance actually works, and you don't need to discuss the losses even though you are fully aware that they are there.  Therefore all of your comments about losses are dismissed.  If you are unable to comprehend this, then that is your problem and you have issues.

The same argument above applies to your comments about environmental conditions.

See,now here is where you went from compressed spring to stiffness. The correct term(and this is the scientific term MH)is elasticity of the glass--not stiffness,as when you use the correct term!elasticity!,then the elasticity value has to decrease in order for the resonant frequency to increase,where as your !!stiffness!! has to increase in order for the resonant frequency to increase

See my post to Webby about "stiffness."  The highlighted text in your quote above is an example of your profound words of wisdom.

If you are going to make a claim like this,then you need to be 100% correct-even in a 4 sentence explanation. But as you can see,you were not,and that is fact MH.

In fact my answers to the questions are 100% correct.  You are just doing your usual shtick and making a spectacle of yourself.

Please go ahead and link to what you think is your best answer.  But like I already told you, all your attempts to answer the two questions were wrong, and you were not going to get any hints.  I read every attempt at an answer by everyone and I did it very carefully and nobody answered the two questions successfully.

Forget it Webby, you are going nowhere fast.  An oscillating spring is a perfect example of resonance.  Duh...

If you do not have a grasp on these basic parts and concepts of resonance then anything you have to say is useless.

You have got a serious case of Sn-50 contamination in your brain and it is impairing you.  Change your diet.

At least I understand resonance.

https://en.wikipedia.org/wiki/Resonance

Yes,i mentioned the external force many times,but it seems that an accurate answer to !what is resonance! needs not to include the actual driving force that provides the energy that is to be stored in the oscillating system. MHs answer to what is resonance,has shown us the leaky storage system,but has left out the provider of the energy that is to be stored.

I mean,there are simple terms,and then there is !half! answers.
How are we to get a JT to oscillate at a resonant frequency if we have no input energy?.


Brad

It is definitely CH2 that is inverted, OR your coils are in opposite phase. Anyway, no big deal, but I would encourage you to note these things on your schematics, because as that scope shot was presented, it does not match up with the probes.
Sure, what is your definition of "impedance" of a transformer?

Let's start with that.

To Quote-the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.

So as far as i can see,in order for the impedance to change,we either have to change the effective resistance,and/or the reactance.
To change the effective resistance,we either have to physically increase or decrease the turn amount of wire in the transformer,or increase or decrease the frequency at which the transformer operates.
In order to change the reactance,we either have to change the inductance value or the capacitance value-or both. This would show as a phase shift,where the current would be out of phase with the EMF that created it.

1-So how else can the impedance change?


Brad

You may wish to rethink your response. Clearly the glass resonates in a uniform fashion, and it does experience a maximum deformation point where it stops before being deformed in the other two adjacent quadrants.

I am not treating it like a pulsed coil and it is not junk at all.  There are no harmonics.  It is directly related to coils, cores, and the like.  I already covered that in a posting.

You cannot trust your eyes. Saying it stops is specific. It's good to have a fast video capture like in the video but that video cannot show everything since resonance is a succession of micro movements. Why does everything have to be so cut and dry with you guys. IT STOPS. Wow. Ok then it stops. No it does not. As two sides move out, two sides move in and this does not mean anything stops. What you are inferring is at one point that complete wine glass STOPS. No. Impossible. There will always be a part of it in movement. Once it breaks, the broken pieces even move. Just because when two sides move out, of course for it to then move back it has to change direction and during that micro second the outgoing does not stop, it just moves in. THERE IS NO STOP. Move out, move out, move out, move in. It moved out just as fast as it moved in. If you want to call the last increment between the last move out and the first move in as a stop, that's, your business but during that time there are so many other places on the glass that are moving to accommodate that move. There is no stop, cigarette break, recess or any other delay. Maybe a coffee break. As fast as it moved out it moved back and during that time there are other movements in the glass. The glass does not stop. It was resonating even before they started the test. I told you this the first time. Everything resonates to everything especially instruments that are prone to physical resonance  like a wine glass. What's the point in resonating if you have to stop. You may as well say marching stops. Making a U turn stops. No it does not. There is a whole wine glass there and not just the rim. Also, did the sound influence ever stop? So why should the wine glass. Oh yeh, then use that sound and blast a coil and see if it resonates. There is no relation there. Physical influences and our coils don't play the same tune. And the audible tones of a pulsed coil is not resonance so do not go there. Now can I go play with the others.

Is a resonant system that is not resonating in resonance?

What is your opinion?

No, the glass never stops, correct.

What it does do is stop deforming in one direction. At that point, maximum deformation is reached for that half cycle.

Was it really much of a cognitive stretch to make that connection? I think yer gettin a little bit picky and splittin hairs there guys.

Ok. I agree there. Like the peak of a sine wave. Spring fully compressed.

But due to possible imperfections and such, there still may be some inertial motion of some portions of the glass actually moving when at that peak. That one vid had shown some amazing distortions compared to some others. Almost slow motion water balloon looking where it doesnt look like everything stops at any point.

No i was refering to effective resistace that is related to frequency increase. .i am not sure why you would say that resistance  dose not change with a frequency  increase,when we know it dose.

Does it? A pure resistance doesn't change its resistance value with frequency.

If it is how you say "we know it does", kindly demonstrate it or link to an example please.

I just asked a simple question ,and get no answer-but just questions.

Your question provoked me to think about modifying the impedance of a coil or transformer, so I tried to engage you to think about it too, hence the questions. I thought we'd explore the concept in tandem.
