Re: Tailplanes

We have a large mass on the end of an arm of quite some length and we have
material deformation which defies conventional calculation.  Could we be looking
at a resonance effect in some flight or ground regime (and if that were the case
could the number of other variables between individual a/c explain why some are
affected and some are not) ?
