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.
