Moment of Inertia: Parallel Axis Theorem 24

1. Hold your hand like a telescope and keep the center of your telescope on the center of your book. Place your finger in the center of your book and spin your book around this central axis.

2. Now place your finger NEAR one corner of the book, not on the corner. Spin your book around this weird pivot and watch the whole thing.

3. Now place your finger NEAR one corner of the book, not on the corner. While still keeping your telescope in the CENTER OF MASS of your book for the, spin your book around this weird pivot.

Compare these three scenarios. Using your data, hypothesize how we could represent the moment of inertia if the axis of rotation is neither the center of mass nor the end, but somewhere in the middle. Combine the perspective of the person with their telescope on the center of mass with the perspective of the person watching the other person’s telescope.
