New notebooks – Classical Mechanics – 3D Rigid Body Motion

I add a series of notebooks on classical mechanics. This series was motivated by a close reading and problem-solving project I undertook in 2014. The focus of my attention was the text Introduction to Classical Mechanics with Problems and Solutions, by David Morin. I focus on generating notebooks on selected topics covered in Chapter 9 Angular Momentum, Part II (General L), which deals with 3-D rigid body dynamics.
