Question about axis of rotation and center of gravity

Yeah, I was pigeonholed in my theoretical mind. Couldn't think about fluids and the like. The OP I think was talking about sth. like biomechanics.

Sorry on my part: Yes! Everything rotation-based in physics changes when you displace the centre of mass, or the centre of gravity if you rotate about the same axis.

The best example I can think of is a pole dancer. These girls must really get some joint lesions from the stress of rotating out of centre.

No need to say sorry. I say I need to say that for not articulating the question well enough in the first place.

Psssstt.
We don't call them pole dancers; It's the 'ballet'.

When someone says COG they usually mean COM.

I agree that what you really want to say is COM, not COG.

LOL. But it really is the best example I can think of.

Thank you, but not your fault in any case. I've got myself in lots of trouble throughout the years for not reading the wording of a problem carefully. The question, I think, is very reasonable. The wording without mathematical formulas or diagrams, is generally tricky.
