Wrong and wrong.

The skyscrapers are oscillating,

again for you to read,

In physics, resonance describes when a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency.

So,, let me help you.

resonance describes when a vibrating system drives another system to oscillate with greater amplitude at a specific preferential frequency.

or

resonance describes when an external force drives another system to oscillate with greater amplitude at a specific preferential frequency.

This is what separates resonance from an oscillation,, all things can oscillate at any frequency short of destruction,, but each one can only resonate at ONE frequency,, it can be driven by many appropriately applied inputs and when the input is driving the oscillator correctly then they,, that is the system,, are in resonance.

Webby:

You are simply not getting it and you are hung up on "drives another system" and forgetting that resonance is energy transferring back and forth in the resonant system itself. You do not need inputs in the way you are stating it, you just need some sort of energy process to put some initial energy into the resonant system.

The skyscrapers are resonating and oscillating. Can you answer the two questions?

The wine glass is 1/2 of the resonating system.
Without the other half of the system,there is no resonance.

Nonsense.

What that quote does not do is describe the mechanism for how the resonance actually works or how the resonant frequency is determined.

I have corrected the above sentence so as it is correct.

Its you who is disgusting. Its you that had to go down that road for sake of insult. You know exactly what brad is saying just as I do, Picowatt does and Poynt does, and everyone else here does. But you have to be the only one that needs to point things like that out just in hopes of making brad look bad. That is your goal. Just a nasty troll of the worst kind.

I suppose you should get a thumbs up from the readers for all that, heh?

You are a lousy human being.

Yes it was a scrap. Brad walked into it because of his comment about my English skills. Yes I fully understand him, but the underlying point is that when he does a technical description then it's a real problem and many times it is not understandable. So a little sting to get him to motivate himself is his just dessert and it has merit. He does need to improve himself yet you don't see him stating that, all you see is bad attitude and defiance for a common sense request that was asked politely several times before.

I don't want a thumbs up or a thumbs down, it's time for Brad to pursue his experiment on the thread that is dedicated to that project. I already stated that I have no intention of going there.

Brad kicked up a lot of sand and some went back into his face. He has been insulting me continuously for two months, did you see? That's what you get when you go haywire.

I don't take any gratuitous pleasure in this whatsoever but you did. You are the worst, lousiest most disgusting human being I have ever seen on this forum and we both know exactly why that is. You out-trolled everybody.

You are the one that began making it a point of Brad misspelling a ways back here. And I had found shortly after that, that your grammar had some sufferings. Shall I go back and find that also? The only reason Brad makes mention of your mistakes is because you use it against him by trying to make a public spectacle of it. Like it wouldnt be in your 'good' nature to maybe send him a pm about it, so that you may 'understand' him better being you made a point of that 'today'.

Fake Characterization?

How many times have you asked or made a statement about someone answering your win glass question 'just' in the last 2 weeks? Do you know that number? Its not fake. Your audience knows.

They are not just meat with eyes.

Just keep hugging on to your dark stain.

You are familiar with the term Dummies, as we have 'witnessed' here recently. So I figured it wouldnt bother you much.

There for my answer about how you determine the resonant frequency of the wine glass was correct,when i stated that-you measure it,along with the methods i provided.

Since MH does not know the difference between resonance and oscillation,, he can not answer the questions correctly.

Any one who at least reads the links provided will have a better understanding of that difference than MH is willing to acknowledge.

ETA:

Don't forget that there are no solid state switching devices that are normally closed,, that would make no sense at all

Yes,it should have been-What determines the natural oscillating frequency of a wine glass,as resonance is a continual oscillation at maximum amplitude at the oscillators natural frequency. And to maintain maximum amplitude,there must be an energy input--the other half of the resonant system.

The only one living in a distorted reality MH is you.
You explained the oscillation of a wine glass at it's natural oscillating frequency.
Resonance is when that wine glass is oscillating at it's natural frequency at maximum amplitude due to an outside force acting upon it.

It is quite funny watching you nit pick on such small thing's like spelling and comers in the wrong place-or not there at all--everything has to be all so perfect.
But when you make a mistake--it's !near enough is good enough!

Well it's time you got your sh-t together ,like you think everyone else here has to---and get it! RIGHT! No more of this !changing! English to suit MHs definition's.
Oscillation of an object at it's natural oscillating frequency is not resonance--full stop.
So your long awaited answer to your own question was wrong,as you were not describing resonance at all--you were describing the natural oscillation frequency of a wine glass.

http://www.physicsclassroom.com/class/sound/Lesson-5/Resonance
resonance - when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion.

https://en.wikipedia.org/wiki/Resonance
In physics, resonance describes when a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency.

https://en.wikibooks.org/wiki/A-level_Physics_(Advancing_Physics)/Resonance
Resonance occurs when an oscillating system is driven (made to oscillate from an outside source) at a frequency which is the same as its own natural frequency. All oscillating systems require some form of an elastic force and a mass e.g. a mass at the end of a spring. All oscillators have a natural frequency. If you have a mass on a spring, and give it an amplitude, it will resonate at a frequency:

Tinman, I don't think the system needs to be oscillate at maximum amplitude, there just needs to be some excitement of the system at a compatible frequency so that the systems "amplitude" is increased by resonance. eg. a transformer could be excited at the resonant frequency with a small amount of energy, or as much energy as could be applied, as well the exciting frequency could be a lower harmonic or something as long as the resonant rise effect is achieved.

I agree with you that there must be an input for resonance because before "resound" there must first be "sound".

I like the definition you linked below.

Cheers

MH

I have re-done your questions and answers so as they are correct.

How does a wine glass oscillate at it's natural !resonant! frequency, what is the mechanism?

The wine glass oscillates at it's natural !!resonant!! frequency 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 most of the energy is stored as kinetic energy in the form of a moving mass,and some is dissipated as shock waves/sound waves and vibration. The instant when the glass is at its maximum deformation, the glass has stopped moving and most 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.

What determines the resonant frequency of a wine glass ?

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

Brad, you puffed out your chest about resonance two months ago and fell flat on your behind when you tried to answer the two simple questions. The simple questions were posed to make you and others think, and now here you are ending it off with yet another failure of the imagination with your inability to separate resonance from a source of energy for the resonance. Or perhaps it's a new 'hook' that you and Webby have latched onto in order to create yet another farcical spectacle.
