The shaking table, or base plate, is not a non-moving mass, but is the coupling factor which transfers the energy from the sum of all the other moving masses from the strongest to the weaker. Another example of majority rule, if you will. Remove the resonance frequency of this coupling factor

Coupled oscillators can do very interesting things above and beyond simple synchronization. Look at the circuit at the bottom of this page with 5 cross-connected neon bulb multivibrators. http://donklipstein.com/sillyne2.html They are symmetrically cross connected favoring no particular

Hi Yes, the settling in is fractal and the path taken to sync isn't the same every time. For a simple way to look at multiple coupled clocks go back to old style filter theory: 1) You have some number of resonators 2) You have some set of coupling coefficients between the resonators 3) You

A frame-by-frame analysis of the metronome video could show the frequency and phase of each of the 32 metronomes as a function of time. Is there a non-youtube version of the video using a well-characterized video format? I'm not sure I would trust the youtube video codecs to keep time correctly,

Hi Google Orbital Resonance. The same process works for *very* large systems, and you can lock at interesting ratios like 2:3 or 1:2:4 in addition to 1:1. Bob On Sep 14, 2013, at 9:34 AM, Tim Shoppa tsho...@gmail.com wrote: A frame-by-frame analysis of the metronome video could show the

Maybe not. We need the math that describes the phenomenon, but it won't come from me. Consider the way that television sync pulses synchronized the sweep oscillators. The pulse has to get there before the oscillator cycles on its own. Similarly, the movement of the common base has to occur before

Not true. It depends on the strength and reciprocity of the coupling. If essentially equal as with the metronomes which are coupled pendulums (the math exists for this), the systems will come to some combination frequency, though as has been mentioned in a many-oscillator system there may be
