Lgtm and tested, great job !

[leovalais]

LGTM, thanks for the changes!

[axrolld]

I only checked the physics part and the tests but LGTM !
A few suggestions but that do not request immediate changes imo (just make sure that the front end will ensure the minimum value of mass / length).

It would be great to comment all the units of the test values in another PR though.

Unresolved conversations should not block the merge.
The suggested improvements are in this issue #9528 and #9529 to be done asap
