Extra Credit - Directionality

Due Thursday 11/8 at beginning of lecture

We have noticed that counterclockwise rotation can be different than clockwise rotation by 3% to 4%, but do not know why. Up to 10 points extra credit will be given if you can determine why. The hypothesis should be conclusively demonstrated. For example, adding tape to the flywheel conclusively showed that there was significant aerodynamic drag.

This assignment can be done as an individual or a pair.
