The density of a rod gradually decreases from one end to the other. It is pivoted at an end so that it can move about a vertical axis through the pivot. A horizontal force F is applied on the free end in a direction perpendicular to the rod. The quantities, that do not depend on which end of the rod is pivoted, are:
  1. Angular acceleration.
  2. Angular velocity when the rod completes one rotation.
  3. Angular momentum when the rod completes one rotation.
