Moment but not torque.

A few weeks ago I posted a note about estimating internal stresses
non-invasively from image data. The immediate application for me was and is
spinal discs and using MRI to obtain stress patterns within the disc.

I had 4 responses in total and compared to the question of "moment vs.
torque" it was a fraction of the level of interest shown for what is really
a question of semantics.

I remain shocked.
