Rotational Inertia Wands
Rotational Inertia Wands
To demonstrate the difference in rotational inertia of the two rods, ask two students to grab the center of a wand and instruct them to rotate the wand back and forth as rapidly as they can. No matter how strong the student with the blue wand is, he or she is not able to rotate it as fast as the student with the red wand.

These two wands have the same mass and dimensions but their masses are distributed very differently giving them very different rotational inertias.
