  4. 4 rotation about the intermediate axis is unstable
  5. 5 Why can't we always get pure (steady) rotation about an axis for a free rigid body? Mystery of free rigid body dynamics can be understood by considering internal moments.
  6. 6 Qualitative analysis of spinning objects. We discuss the qualitative analysis of a spinning body, where the body is either spinning rapidly or is a system with a connected rapidly spinning rotor. Th…
