Question: When the teeter-todder beam is in resonance, does applying a load to this beam throw it out of resonance or does it just suck down the oscillations?
I'm having kind of a hard time figuring in a Q-factor with a mechanical device like this. Seems there should be one and if there is, then your complete system should have a bandwidth just like any resonant circuit. What this should translate to is if you can get a high Q-factor and find that narrow operating frequency, your device should literally tear itself apart--probably not really what you want. If the Q-factor is lower, then there should be a fairly wide operating frequency where you can still maintain resonance. That should also mean you can vary the load somewhat without ill effects on the oscillations/resonance.
