## Moment of Inertia Challenge

*The Moment of Inertia Challenge*

Determinig the moment of inertia about the center of mass *mathematically* of an object with complex geometry is not an easy task. Consider, for example, the empty 3D filament reel shown in Figure 1, an empty 1-kg Polymaker Polylite™ PLA reel. With its holes and intricate axle design, the best way to determine the moment-of-inertia about its center of mass is via a laboratory experiment. Voyager (or PocketLab One) is mounted to the reel for data collection.
