Well, that was quite a ride and it revealed a lot about the dark side of human nature.

What's interesting is that I lucked out on my wine glass question in the sense that you can't just plug the question into Google and in 0.012 seconds get the perfect answer spat back at you.  You actually have to know your stuff and apply your knowledge to successfully answer the two questions.  Google is not going to readily spoon feed an answer back to you.  And that frustrated our contenders, I am sure.

Ironically enough, a resonating wine glass is just a mechanical version of an LC tank circuit.  L = the spring and associated stiffness of the glass, and C = the glass itself and associated mass of the glass.  Nothing could be simpler, and nobody got it.

Her are my answers again:

Wine Glass Questions - Answered

How does a wine glass resonate, what is the mechanism?

The wine glass resonates by cycling energy back and forth between two forms, kinetic energy and potential energy.  The instant when the glass is not deformed, the glass is moving at a maximum velocity and all of the energy is stored as kinetic energy in the form of a moving mass.  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.  In between these two states, the energy is stored as combination of kinetic energy and potential energy.

How is the resonant frequency of a wine glass determined?

The resonant frequency of a wine glass is determined by a combination of the effective moving mass of the glass and the effective stiffness of the glass interacting with each other.  The higher the effective moving mass of the glass, the lower the resonant frequency.  The higher the effective stiffness the glass, the higher the resonant frequency.

Now look at this clip:  https://www.youtube.com/watch?v=XggxeuFDaDU

Then ask yourself these questions:

How does the bridge resonate, what is the mechanism?

How is the resonant frequency of the bridge determined?

Are there any light bulbs going off in people's heads?  Who has the courage to say something positive?  Or are you all just submissive sheep and afraid to say that you learned something interesting and useful that can be applied to other situations because Big Bad Brad is watching?

In the quoted posting above, you make yourself look like a fool with scrambled brains.  It's enough to make a grown man cry.

The truth always hurt's some MH.
I feel your pain.

There is nothing in the question about the wine glass receiving energy.  Is this a failure on your part to think?

The question is--how dose a wine glass resonate--what is the mechanism?
Well the very first thing that happens MH,is it receives energy from an out side source--the very first part of the mechanism MH. No energy input-no resonating.

Er-wrong again my ass.  The question does not ask about energy dissipation, it just asks how the wine glass resonates.  Don't you dare get into one of your insane "car on a hill" arguments.  It's yet another failure on your part to think.

Sorry MH,but you bought the energy thing into this your self. Quote !!!ALL!!! the energy is then stored as kinetic energy.--->No MH,some is dissipated--all energy is not (NOT) stored as kinetic energy-->you got it wrong.

You never answered the two questions completely and properly.

As it turns out,your two questions were answered more completely and correctly than you did in your big reveal lol.-->You missed two of the most important part--energy received--energy dissipated lol.

No, I'm afraid SO.  You are stepping outside the bounds of the question again.  It's nonsensical idiocy like that that would get you sliced to pieces in no time on a serious electronics or physics forum.  They would think you were nuts.

I think most here are starting to see who is nut's here MH.
No resonant systems around an ICE
No resonant systems within an ICE
Your silly J/FET device makes no sense
And so on,and so on,-----

But you don't actually say the correct thing in your answer, you are just re-spinning your words in an attempt to make them fit.  I don't give a rat's ass if "the structure of the glass/crystal that the wine glass is made from" will determine the stiffness.  You did not say stiffness and it was never in your mind.  Stop the BS.

Stiffness is the incorrect term to use. Elasticity would be the correct term to use,and guess what MH,i used that very word to explain your questions many many posts back lol.

You completely failed to answer the two questions, mister "resonance researcher."  You were all pumped up with attitude at the beginning of this thread about resonance and as it turned out your puffed up chest was a fake because you could not articulate how a wine glass resonates, or how its resonant frequency is determined.

Sorry MH,but myself,smokey and others gave more accurate descriptions than your big reveal did,as we included energy received,and energy dissipation,and used correct terms like elasticity in stead of !!stiffness!!.

Based on what we have seen, you would be the laughing stock on any serious electronics forum.  The Tinman is only cool when he is in his cocoon on this forum.  You would be eaten alive elsewhere.  That's the harsh truth.

Based on what we have seen,you are delusional.
This thread is full of your mistakes,and i bet you are hard pressed to find one instant where you have had to correct me,as most of the thread is me correcting you--and even you correcting your self lol.

You have your self a nice day now MH.

Webby:

You turned dark and creepy quite a while back in this thread.

Wattsup:

You will be fantasizing about your stuff for a long long while.  And you got some push back.  "Half-coil syndrome" is simply ridiculous.

The discussion about the resonating wine glass was useful.  The delay was to see if anybody was up to figuring it out themselves and it was also Brad's karma getting back to him.

Anybody that says disparaging comments about the wine glass explanation is just caving into peer group pressure because you know it is right.  And that's pretty sad.

How does your whineglass Karma  lesson change Tinman's methods for tuning to resonance  ?


How could this lesson improve or change his technique ??

You have to be aware that there are always two components to think about when it comes to resonance.  Just saying "it resonates" doesn't cut it.  Maximum resonance amplitude when you factor in losses equals a maximum power burn-off.  Where and why is the energy being lost, by what method?

Smoky talks about "making your Joule Thief resonate at the same resonance frequency of the toroid."  How does the toroid resonate, what are the two components?  What are the magnitudes of the variables associated with the two components?  If one of the components is a five nanofarad capacitance, how much energy can be realistically stored in a five nanofarad capacitor?  If the resonant frequency is very high, that will naturally filter out any amplitude in the variables because all components eventually become subject to low pass filtering which reduces all high frequency amplitudes.  So how much energy can realistically be stored in a self-resonating toroidal core that forms part of a Joule Thief?  Then if the Joule Thief itself is "supposed" to resonate, and that is supposed to be at the same resonant frequency of the toroid and that is a very high frequency, then this is what follows out of that:  There are two energy storing components and two variables associated with the toroid, and two energy storing components and two variables associated with the Joule Thief windings.  Those four components and four variables that are supposed to "sing together."  How do you measure them, how do you see them interacting?  Take one step back, plot the four variables for the four components on a timing diagram by hand and try to construct your "magic resonance."   How much energy is there in each tank and why should two resonant tanks do something special?  Assuming the two tanks are running at a very high frequency, will they spontaneously gen-lock or will they just beat?  If they just beat then "making the two resonant frequencies the same" will be impossible for all practical intents and purposes.

The point of the exercise is to be conscious that there isn't "just 'resonance.'"  There are two energy storage components and two variables and you have to be aware of what is going on.  Just twirling pots and "looking for a big increase in amplitude" is not going to cut it.  Prove me wrong if you disagree.

Resonance is an explicit physical process and on your bench if you are going to be "researching resonance" then you should be aware of all aspects of that physical process.  Clearly, everyone that tried to answer the two questions either only got half an answer, or they said nonsensical gibberish, or they wrote a small book that was ridiculously complicated and philosophical.  Nobody just laid it on the line for the wine glass because they clearly did not understand the simple process that was taking place, and it is the same simple process that takes place for all forms of resonance.  It always has the same signature.

Instead, we saw a grotesque spectacle of ignorance, stupidity, lies, anger, willful ignorance, willful stupidity, gross exaggeration, misdirection, and petty bullshit.  We saw everything except a nice clear answer to the two questions that demonstrated that the person answering had a clear understanding and a command of the subject matter.  Instead of a fun challenge and an opportunity to learn, we saw garbage and the worst behaviours coming out in people.

No, it is elasticity as Brad has said...measured by Young's Modulus.

Bill

Stiffness factors in the shape and size of the object being considered.  The correct word is stiffness.

But in this case, just getting the concept across is what counts, that's what's important.  In that sense the choice of term, springiness, stiffness, elasticity, is not so critical, understanding what is going on with resonance is what is critical.

How does a bell resonate, what is the mechanism?

Answering, "You hit a bell at it's resonant frequency and it starts to resonate" is not an answer.  It's a bloody joke that shows that you have no clue what you are talking about.

That glass in the glass breaking video had shown some 'extraordinary' elasticity.
