Art,

First, I re-state your basic situation to see if I understand it:

You have a constant speed around a circle.
Yes

This, indeed does suggest the
normal radial acceleration (what is that... V/R^2 ? I don't remember).
Yes

We
know that acceleration is defined as a change in velocity, where velocity
consists of both speed and direction.
yes
Speed being the distance traveled
along a path per unit of time
yes
.. So, if we change the velocity direction (to
always be tangent to the circle) , but not the magnitude (or speed), then
we
have acceleration - what we call radial acceleration.

Not sure if I follow that.with respect to terms If what I said is what you
are saying
AOK

In the case of circular course constant speed energy must be inputed
to overcome radial force and ofcourse every action has an equal and opposite
reaction
I believe this all to
be true. Are you with me this far and do I have your meaning correctly ?
It would appear so subject to my statements above
It would apear that it is so



Assuming the answers are yes, I continue to go into the part about energy
"transpiring" into something.

o.k.

You say:

"the energy input should have transpire3d(sic) into acceleration

buyt(sic) instead added another vector".



This appears to be saying that something (the acceleration) is _not_
produced by said energy ("should have...") , but rather something else
_is_
produced ("...another vector").

I am saying that energy is inputed to maintain constant speed which can be
seen
as creating a CONSTANT force vector at a tangent


The words you use in these two parts describe only one thing, yet you
imply (by the words: "buyt instead") that they are different things.
Yes because when the radiator is straight it is phase change that creates
cyclic
current change ala accelleration.
In the case of a circular radiator I understand that there is no phase
change
a nd the radiation vector is a constant. This may well be the nubb of the
misunderstanding.

Radial
acceleration is a vector directed toward the center of the circle. It
is
the 'radial acceleration vector'. Therefore, if your energy _DID_
"transpire" or more correctly, produce this "other vector" then it _DID_
indeed go to produce the acceleration -- because this vector _IS_ the
acceleration. They are ways of talking about the same thing. I can't
figure out what you mean.



Whether or not it takes energy to cause this circular acceleration is
another matter I haven't addressed yet since the basic premises must be
cleared up first.

I also think you are wondering if this radial acceleration does some
special radiation that is different from the radiation of the charge
simply
by virtue of its 'normal' non circular movement. However that's also
another issue, after we clarify the basics here.
That is correct in that current variation is constant in one case and cyclic
in the other
which inferes that over a cycle the area under the cyclic current curve is
the same as that seen
under a constant curren and it is this comparison that I was looking for in
literature.



Then you say:

"In both cases we have constant speeds but we also have

a difference in phases. "
Yes I see the phase change as shown by the current curve.
and in the case of circular motion I do not see a phase change ( I cos phi )



You keep mentioning "constant speed" yet we are talking, I thought,
about an antenna with RF current in it.

Yes

If this is the case, there is _NO_
constant speed of the current. It is constantly varying in a sine wave.
It has a sinusoidal speed variation and therefore a sinesiodal
acceleration
(acceleration being the derivative of velocity and cosine being the
derivative of sine)

Yes I agree. That would be of the value I cos phi with cos phi providing the
sign wave
I believe we are saying the same thing

So you seem to be applying two concepts (constant
speed and . sinusoidal variation in speed) in one situation. I
believe
this is invalid and may be the source of your confusion.

It may well be a difference of terms applied but I am pleased you follow
the main drift of what I was saying so you could be well armed to
correct me where I was wrong.



Also, I don't know where this "phases" comes from. Lost me here
unless
you are talking about the relative phase of two different windings of this
circular wire you mentioned a while ago...

No that was in reference to the new model antenna that I am making

Please explain what I have wrong, if the case.





Enough said. I have typed up the program [...snip...]



What language are you programming in and what formulas are you using ?

Steve it is a computor program that chooses or finds the best dimension for
an inputed variable.
plus can handle a large number of segments'''''''
I have many circular radiators in a horizontal position but at different
heights.
All have a gap in the circle and half are wound in an opposite direction to
the other coils.
All of these loops are connected to each other by vertical members the
length of which depends
on the cosequtive height of the loops... These vertical portions become high
voltage and low current member
when requiring best efficiency. The impotant thing in this arrangement is
the correct selection of the up
then down positions of the loops for the feed input requirements.
You cannot research the best positions of the loops with Roy's program as it
is the basic of basics and
posibly not enough segments available but most programs of today DO offer
many variable dimensions
with more than enough segments ( I used 20 segments for each loop)
I am very pleased that you connected the dots of my question which shows I
am not a troll.
My spelling is bad because this new computor has small letters on the screen
and with a
3 Gig Hz speed it is difficult to keep up to speed with a braille keyboard
Hi, Hi.
My very best regards to you and thanks for hanging in there as opposed to a
derogatory comment
