Hi Gerry,
before talking about the experiment: I'm shure, a slow ramp up will
_not_ cause the rods to rock! It's certainly the repeated
application of a small force, in the Eigenresonant frequency of the
JL, which does the job. - Remember the children's-swing: it can be
set in appreciable movement, by pushing it with your finger's little
force only, if applying the pushs periodically, in the right moment.
To recognize the displacement of the swing, caused by one static
application of the small force, you'd need to have a very close look
at a small displacement (this corresponds to the experiment
proposed). In extending the analogy, your finger would push the
swing in a frequency of ~545Hz (like a sewing machine ;-)), which is
orders of magnitude faster than the Eigenresonance = quasi static.
I "think" we can and will try to do the experiment. It corresponds
to measuring the effect of a static force of around 0.04N (40 ponds)
or less, on the JL rods. This will lead to a very small
displacement. And the force will be applied 545 times per second
(_not_ 60Hz!). I see at least 2 problems we must overcome, in order
to realize the experiment:
1.) Very slowly bringing the power resp. HV up on the JL,
remembering the HV is coming from an induction coil (not a pure DC
source). This problem is probably easy, by means of the Andiruptor,
where we can ramp up the end-charging-current easily, while not
starting at zero.
2.) Mounting a displacement measuring device at the top of the JL,
which is not disturbing the field, and can be recorded without risk
for the observer. Some ideas to this are developping.
So, the experiment will not be a one moment action, but helping to
clarify the dominant mechanism, which is moving the rods of the JL.
I'll report on the outcome. If it differs from my model-ideas we
have a more interesting subject! ;-)
Thanks Gerry, for your answers and proposal.
Cheers,
Kurt

Hi Kurt,
Here's an experiment for you. Can you very slowly bring the power up
on the JL but not to the point of starting an arc. I'm curious how a
60 Hz field can cause an oscillation of 1 Hz. I'm thinking the
sudden application of power is causing its natural response. If so,
maybe a slow ramp up will not cause the rods to rock.
