Vibration (Jerk in physics terms - the derivative of acceleration da/dt) is a bigger problem over time. The instantaneous forces from da/dt can be crazy big. #andy aka what are you making :-) | |
| Mar 12, 2014 at 1:43 | comment | added | markt | That's an interesting point about XTAL's. If spun (or otherwise accelerated) fast enough, is there measurable physical distortion of the crystal? If so, how does it affect piezo-electric behaviour - variations in frequency, amplitude, phase, duty cycle? | |
