So, what action would you call them, I see absolutely no evidence of torsional movement as they are compressed & this should show on the wide, thin cross section if it were present.


Now we're into some different stuff! What you're referring to are called "volute" springs. These are basically a very thin "beam" wound into a spiral coil. When compressed, one "side" (it's wound in a spiral) is placed in compression while the opposing side is placed in tension, thus mimicking beam loading but not in a planar fashion.

I have nothing at all against the French, for the record.
Sorry, le faux pas es moi, mon ami. I have midget respect for the French en tot, their metallurgists and some of their non-miltary gun makers like Granger-- I recall what America's best field General- George Smith Patton Jr. once said about the French- "I'd rather have one French division ahead of me that 3 French divisions behind me"--and Patton spoke fluent French-go figure
