Good on the wit, but your comment is still not true.
You are of course entitled to your opinions, just as I am entitled to ignore, disagree or agree with them.

Exactly Webby.

Soft iron may have a high value of stiffness,but a very low value in elasticity.

As i stated in one of my replies to MH-long ago,the makeup of the glass(crystal)will determine the value of elasticity,and it is that value of elasticity that will determine the resonant frequency of the wine glass. Even with keeping to the same size and shape of wine glass,we can raise or lower the resonant frequency of that wine glass by changing the value of elasticity in the glass-change the type of glass used.

Brad

Please go ahead and link to your quote about elasticity because I don't remember anything like that.  Feel free to link to your best answer also if you are claiming that you answered both questions successfully.

Well I have made thousands of postings filled with good solid information and in the earlier days I helped people understand their circuits all the time.

MH
I Honestly feel your Big reveal will in no way change any builders resonance hunting technique,
not one Iota .

the builders mentioned many very simple methods they use for this purpose ,and honestly they make perfect sense .

from my perspective having had the privilege of several very good Mentors in this EE field and having witnessed many very good resonant hunting techniques by very experienced persons on threads at this forum and elsewhere.
,I feel your big reveal is a big let down for the builders .
and I strongly suspect your are fetching for any true reason for this fiasco  other than some Bragging right and a chance to belittle your foe and others here at the playground !

Honestly I can completely understand your ignorance on ICE science.. its quite understandable.
what I cannot understand is your willingness to open your mouth as an authority when you are completely clueless.
and this is very troubling.. considering where we are ..and the depth of what is touched upon here.

Regarding the question about which wave form was the correct one, I'll go out on a limb and say neither one, because I'm pretty sure you inverted CH2 (the current channel), and I did not see mention of this. Therefore the wave forms could not appear as they do with the probe orientation as depicted.

If CH2 was not inverted, the primary current would be lagging the secondary voltage.

How do you get an EMF across  the secondary before current flow through the primary?

And there you go
That proves  that you did not even bother to read the answers given-it was just an automatic wrong from you.

Your definition is fine MH,, your usage is not.

I do not care if you think I did or did not answer your questions.

No crack on the antonym,, that is the truth MH,, they are opposites, not basically the same thing.

Show me where stiffness is a property of returning to the original condition after being distorted.

Show me where stiffness is anything other than the resistance to being distorted or changed.

http://www.merriam-webster.com/dictionary/complementary

Where does it say that they are basically the same thing within this definition MH,,

The stiffness, or rigidity , will affect the resonant frequency, BUT, it is the elasticity that converts the motion of the system and then returns that conversion back into the system creating motion once again.

Stiffness does not do that, stiffness is more like a one way event.

You did not answer the two questions successfully.  If you disagree, then link to your answer because otherwise it looks like you are bluffing.

You can have the rest of this conversation with yourself into the wind.

Just more mean-spirited ugliness.  Of course I read the replies and there were quite a few.  It would be ridiculous for me not to, therefore your statement is ridiculous.  You made several attempts.  So do you want to link to the two you are talking about or not?

Chet:

You are spinning a tale that doesn't even exist.  This is not about "resonance hunting techniques."  Just that phrase says so much about your bias. There is resonance gold in them thar hills.  This was not done explicitly for the builders.  This stems from a discussion between myself and Brad and anyone else was welcome to take a stab at answering also.  Brad agreed to the challenge.

I admitted that I was wrong about resonance for an ICE, that's it.  Nothing there was directly related to the turning of the main crankshaft, which is what I had in mind.  An ICE is really a synchronous machine more than anything.

The issue was for Brad or anyone else to demonstrate that they understood resonance for probably what is the most common cliche when we think about resonance, the wine glass.  Nobody got it, and that is food for thought for the resonance researchers.  Instead of moaning there should be a desire to learn more and improve your craft.  Now they all understand it and they are better off.  You are welcome.

Thanks for the compliment, time is still at her / your side.

Did learn lots from you, really a big THANKS, thats why we did invite you here, serious!

But: https://www.youtube.com/watch?v=cPtL3S1v4jw

V, is Fem, flirting, botox
I, is Male, doing, going for new worlds

Current world:
Fem, mostly looking for security, digital thinking, demanding,
Male, adventures, looking for a bigger world.

Behind digital, is bit like 4-stroke, but digging in ports from a 2-stroke is analog the artist, thats why Honda did kill the 2-stroke, type's like: Luc and other could beat biggest motor factory named: Honda.

Stap over you're fears, investigate with these GUY's analog resonance, together, not demanding!!

See again the supplied patent, nothing to do with CO2, where is SCIENCE, but look again:

Johan, your peers should be embarrassed and frankly horrified by your behaviour and you should be flagged for that.

You did not answer the two questions successfully.

Neither did you--your own questions.

You insist that everyone here use correct and accurate terms used for description's,telling me i need to brush up on my English,and yet you deem it ok to use loose terms when it suits you--such ass stiffness--which is incorrect.
You also clearly state that all the energy is then stored as kinetic energy during 1 part of each cycle.
This is also incorrect,and you too would be booted out of one of your EE forums you speak so much about for saying rubbish like that.
If !all! the energy was stored as kinetic energy in one part of the cycle,and then all that energy was returned during another part of the cycle--where is the energy to create sound coming from?

You wanted so much to be right and accurate,and you wanted to make us wait some 7 odd weeks for the big reveal,and it turned out to be a flop-->wrong-->and you know it.

Of course,once again we do not see any other EE guy here point out your mistake's,there more happy taking on others(hobby bench men),about things like phase shift not being real--another of your rubbish statements MH.

If you want me to post the reply where i stated elasticity,then you go find what number post was your first post of your two questions,as im not going to spend hours looking for something you missed.

Resonance is a way of storing energy using AC.  It was a big fish claim.  The only reason you see amplitudes increasing with resonance is if some external source is providing energy, a la pushing a child on a swing.  Eventually the supplied power is equal to the burnt off power in the resonance.  i.e.; maximum resonant amplitude in an resonating electrical circuit typically means maximum power burn-off.

Some external source is providing energy ;)
