Bratislav, I liked your post on tube stiffness and the 4^ power. Now that
surely affects deflections purpendicular to the axis, but what about
torsional deflection and vibration when using stepper motors? I guess
there are 3 degrees of deflection, axial, longitudinal and torsional.
Just speaking about the shaft or tube, not the mount. Longitudinal is a
throw-a-way. Ah, the art of amateur telescope making can get into the art
of structural analysis, can it not?
