This is a clear demonstration that you do not understand resonance.

Aint that the truth ;)

And so the day came when the teachers became the students.

The guitar string is self-resonant, just like the wine glass or a tuning fork or a bell.  The air around the string drains energy away from the resonating guitar string in two ways.  The moving string is pushing its way through the viscous air and therefore there is friction.  The moving string also couples energy into the air in the form of sound waves.  So you can simply say that the air is damping the resonant string and draining energy away from it, like a resistor in a parallel RLC circuit.

That's why I said you have apparently been bluffing your way through this.

OK

What if you were sitting in a bell tower, drinking wine from a glass while playing guitar and pushing a small child on a little swing with your foot?

Would the universe as we know it implode?

Self-resonant??? (SRF)

So now there is a capacitance within the wine glass,, guitar string and a tuning fork??

How does the air drain away the energy without changing the frequency,, how does that air around the guitar string make the other strings amplitude increase so that they can be causally observed??

In short the air is in resonance with the string.

This is a classically used example that you have called ridiculous.

Okay Webby, so you have been bluffing.  And Brad is off in La-La Land backing you up.  There is mechanical capacitance in the guitar string and the wine glass when you analyze the physical systems.  I stand by what I am saying and for this basic stuff I know what I am talking about.  So let's just put this whole damn thing to bed.  Just watch the new thread about the vibrating magnet on a stick.  It's like a lab experiment for a junior college physics class.  See if anybody arrives at a conclusion or if it just withers and dies.  Don't expect to ever see a "resonant Joule Thief" thread, which was the reason I entered into this sometimes-crazy debate in the first place.

Is it that hard for you guys to accept?
Too big to be taught by those you think are beneath you?.

Did i,or did i not explain,show and provide evidence to MH of existing resonant systems that exist around an ICE,that greatly improves performance and efficiency?,when he said they do not in any way,shape ,or form.
Did i ,or did i not provide evidence and prove to MH ,that resonant systems exist within the ICE it self,that also improve performance and efficiency ? when he said they do not in any way,shape ,or form.
The teacher became the student ;)
Have i,or have i not provided correct and accurate information and examples of what resonance is?.

Wow indeed.

Yes Mr J/FET,i bet it is.
Looking back on your mistakes throughout this thread must be painful :D

How do you link the oscillations of the wine glass and the Tacoma Narrows bridge?.

If my mistakes are a mouse, then your mistakes are an elephant.  But of course that is problematic territory for your psyche.  It's up to you to link the oscillations of the wine glass with the Tacoma Narrows bridge in order to demonstrate some competence in the subject matter.

After the recent o'scopes 101 foul up, I thought your comment was a bit arrogant...

Carry on...

When did i claim to be an Oscope guru?
And just for the record,the way the scope was set up for that test,did indeed show that the yellow trace was leading the blue trace when the yellow trace was to the right side of the blue trace.

I have no problem being the student,and learning as we go along.
MH should accept the fact that he too is also the student some time's--your never too big to learn.

Quote from: Miles Higher but losing altitude...
The skyscrapers are resonating and oscillating.

The buildings may be oscillating but how can
you prove they are in resonance? :o

How many resonant frequencies does a tall
building have?  With anti-resonance dampers?

Quote from: Miles Higher on his way down in flames...
No Webby, I am dead-on accurate.

A classic example of a lamely weak desperate attempt
to defend a losing stance. ;)

Quote from: Miles Higher as he crashes...
Now _my brain_ is hurting from reading this foolishness.

Must be a wedgie - those can be painful.  Did you not
deploy your chute? ???
