1) Sets of equations usually look better if the are aligned on the equals symbol. Use right-align these.

2) The usual decoration for vector symbols in physics is an arrow as produced by the LaTeX \vec{} command. You use a bar. Is that the convention in multibody dynamics?

Feel free to improve that.

I use bar mostly because it matches my handwritten notation. I plan to add the handwritten notation to the notation page. I also plan to go over all of the notation and make it more consistent. There are some warts in the text that aren't as consistent as I'd like and also some notation that may be used for two different things. I'll stick with bar for vectors for now, but could be open to a change once I take an editing pass at all the notation for consistency and uniqueness.

I just tried \vec{} and it puts an arrow on top of the symbol. I am not a fan of that, so I doubt I'll change to that notation.

The other common notation for vectors is to use a bold font. I'm not advocating any particular notation. Just wondering if using a more "standard" notation would make it easier for students to read other textbooks.

I guess it could, but I will stick with \bar{v} for vectors.
