[OM] Tripod resonance

[List, OM]

An interesting article regarding tripods was brought up in another group.

I can't help but wonder if "the stands extracted to one third of the maximum
length and loaded with 70% of their working load" wasn't chosen to give the
wooden tripods the best performance. Who carries a tripod that is tall
enough to use at one third its length? I would think that the length would
have a dramatic influence on resonant frequency (but hopefully your tripod
isn't a musical instrument).
