Good resource for 3D dynamics
I want something that satisfies the following.
 * 1) Covers inertia tensors, equations of motion, angular velocities, working from body-fixed frames etc.
 * 2) Is free and can easily be downloaded.

I do not want discussions of Hamiltonian or Lagrangian mechanics: I want something basic to simply set problems up. I'm not too clear on all the rules for rotational dynamics. The focus is more engineering than physics incidentally; however, I am not interested in homogeneous coordinates.--Leon (talk) 19:30, 27 March 2019 (UTC)
