not so on Top of this

The class was told to find a partner and a table then given a description of materials 6 pennies, two paper plates, a pencil ,and tape. Then came one final instruction, "make a top."

1. How did this activity relate to the engineering design process?

The engineering design process includes four main steps, design, build, test, and reflect. This relates in the fallowing way. First, we to the best of our ability, tried to find the center of a plate and poke a pencil through. Then we traced out where each penny should go in order to make them equidistant from the center and each other. Then we built. Th planned design worked slightly, so back to the drawing board, we remapped the center and the pennies and the top spun. 

2. How does the activity relate to angular momentum and moment of inertia?

Moment of inertia involves the distance of mass from its center and how it is spread out. We had no perfect means of finding the exact center, thus the top was for some time doomed to wobble. Due  to the world refusing to be frictionless, the angular momentum of the top had to be accounted for to keep the top rotating upright as possible.
