MH's ideal coil and voltage question

[MileHigh]

You have not provided one example where an object will resonate by it's self,and your bell,and wine glass examples have been proven to be wrong.

Proven to be wrong in your head only.  You are your own best enemy.

[MileHigh]

The reason you cannot,and will not provide a circuit for the ideal voltage source in question,is because it dose not,and cannot exist.

Ah, so it was a "trick" question.  Knowing you, I actually believed that you were literally asking for a circuit for an ideal voltage source.  It's that bad.

[MileHigh]

Your answer is based around a circuit that cannot exist--and the proof of this,is by way of you not being able to draw such a circuit for the ideal voltage source.

And I see we have gone full-circle here and we are starting the discussion over right from the beginning.  We are back to the "problem child" at school that can't cope with using simple abstractions to better understand how circuits work.  It's information overload.

Not a problem.

or using the understanding to make an emergency power supply just in case the planes power supply failed when you could not deploy a prop driven generator.

A system in resonance,, it is kind of fun. 

The air is interacting with the bell and its oscillation,, there is an exchange of energy in that transaction that will reduce the amplitude of the bells oscillation without changing the frequency.  This interaction is soundly demonstrated by the very sound you here,, the pitch would change if it were not in resonance.no.

That is correct,and that is the bell oscillating at it's natural resonant frequency. The bell will ring down(the sound level from the bell will reduce over time)due to dampening by both the air it sits in,and the bells own resistance to change(elasticity).

In physics resonance describes the condition where the external stimuli interacts with ONLY the amplitude,, not only increasing it but any change to that amplitude

And that answers your question.
The bell has no external stimuli acting upon it,it has a dampening effect from the air it resides in-not a stimulant effect from the air it resides in.
The bell can only resonate when an external stimuli acts upon it to maintain or increase it's vibrational amplitude.

.and yet you have seen this with your pulse motors and PM's,, your RT,, you have shown many things that show this interaction being a two way thing.

The RT works by deforming the magnetic field of a PM,and then letting the field reform at the same time the electromagnetic stator field is collapsing.This causes a large reversal of the magnetic field the stator coil B see's. Due to the shape and design of the stator core,this field also travels around the stator core to the other side,to create a magnetic field at stator core A,due to the flux path of the core it self. This is why the motor speeds up,and gains torque when a load is placed on the outer coil of stator B.

I was schooled on what resonance is by a group of engineers that had to know there stuff,, I was very young but remember the differences between an oscillation and a system that is in resonance,, in there line of work it could be the difference between an airplane flying nicely through the air and one that rips itself apart,,

With the planes,that is aeroelastic flutter,the same thing that bought down the Tacoma Narrows Bridge. The outside force acting upon the plane,is the wind due to the planes own motion.

With some of the reply's by others I am wondering if in the electrical world the difference is not taught because in that space there is no difference??

When an inductor resonates,it's amplitude is at a continuous maximum that can be gained from the outside force acting upon it.

And you fall flat on your ass for the 10,000th time.    Plus your bloody definition doesn't even make sense.  Like I said, it just never ends.





But no!  But no!

Here is what an ideal torque would be:  A system that applies the same torque to the spinning flywheel regardless of the angular velocity of the flywheel.

An ideal torque is an ideal energy source. An ideal torque will maintain it's chosen value,regardless of the opposition force placed upon this torque.

Gee it's hard with you MH.
Im sorry to say MH,but in engineering,torque is not only related to flywheels,and so your answer is very limited(like your self),where as mine covers the whole spectrum.
Nice try,but you missed the boat again.

For starters, there is no such thing as an "ideal energy source."

And yet your question is based around such a device lol.
So it's much like asking--how fast could a flying pink pig go ?.

If you understood what has been discussed ad infinitum already, you would realize this right away, it would be a no-brainer.  And you would never in a million years use the term "ideal energy source."

Your ideal voltage source !is! an ideal source of energy.
For a voltage to be placed across an inductor,and a current to flow through that inductor,requires a source of energy. Since your question only has two components,1-the inductor,and 2-the ideal voltage source,then the ideal voltage source must be providing the energy.
You never managed to provide an example of a voltage source that dose not contain energy -but no surprise there

It is funny to watch you try and squirm your way out of mistakes you know you have made lol.
You never like answering questions asked of you either-->like,when is an inductor resonating?,and when is it just ringing down at it's resonant frequency?.
I mean,we have all discussed this on many occasions,and TK has shown a coil ringing down,and a coil resonating many times. But you will not answer those two question's,as you know that means that your self resonating wine glass and bell theory will fall in a big heap.

I will try one last time to try and show you what resonance is,and when something is resonating,and what oscillating at a natural resonant frequency is.
It dose not come much more simple that this.
