Add parts, modify analysis parameters, click "Solve", then "Play". X-axis: Red. Y-axis: Green. Z-Axis: Blue. Adding default box and solving default analysis parameters shows Intermediate Axis behavior.

Things spinning in space can do things we might not expect so I created this app to help me get
more "hands on" experience. If you use it and have feedback, suggestions, or whatever,
please reach out to me via my LinkedIn page: Bill Tandy

**General Instructions:**

- You can add simple shapes using the buttons at top
- Change spin speeds and how long you animate for with the panel on the left
- Add measurement points to plot positions (it's optional)
- Click "Solve" after setting things up
- Click "Play" to animate the solution
- Open plots by clicking on them in the left-side panel

- This app is designed for desktops; phone screens are probably too small
- I keep things on the X-axis to simplify the matrix math
- The math is based on this page: Berkeley Rotations
- Plotting many points can slow the app way down
- Watch a great video describing things here: Veritasum Spinning Bodies
- If you add the default box and keep the default analysis parameters, choose "Solve", then "Play", you'll see the Intermediate Axis "flip" that can be non-intuitive
