Hello, I have a question about a spinning symmetric top:
When the equations of motion are solved, they are solved in two frames--the space frame and the body frame. I understand the space frame, but in the body frame you are looking at the top from a frame that is rotating with it, right? So you don't see any rotation, so do the values of wi mean anything?
I think my thinking is wrong here (but I'm not sure why), that although we are in the body frame, we still see w. In fact I know what the solved w looks like, but I just can't wrap my head around it. If there are any good animations for this kind of thing, I'd appreciate being shown them.
