Torque & Rotation: 2 Axes, Tilting Possible?

AI Thread Summary
Torque can enable rotation around two axes simultaneously, which can be mathematically represented as a single combined axis of rotation. This concept is illustrated through examples like gymnasts performing twists and flips, where their motion can be decomposed into angular velocity components. While rigid bodies typically rotate around a fixed axis, non-rigid bodies, such as divers, exhibit more complex motion that may not conform to traditional rotational definitions. The discussion emphasizes that while the appearance of dual-axis rotation exists, it is often a result of combining angular velocities rather than true rotation about multiple axes. Understanding these principles is crucial for analyzing rotational dynamics in various contexts, including gymnastics and diving.

Who knows how it appears to you. It's like explaining how colors appear.Not a good description of what actually happens, as explained in post #45 on others.

Then what about the rearranging body parts part? Does rearranging body parts have to do with any of this?

Sounds like a serial killer making space in the fridge. What's wrong with saying "relative motion of body segments"?

Ugh, no, I meant rearranging one's own body parts as in moving them around as they are diving. Relative motion of body segments is good too, but there is no need to make what I said seem what it is not.

I know this is probably science talk, but still...
