Resumen de Enhanced Rolling Moment of Inertia Demonstration
Jerome C. Licini, Yoon Jung Choi, George Awad, Richard O. White
Moment of inertia is often illustrated using the classic demonstration of a solid cylinder and a hollow cylinder with identical mass and radius rolling down an incline, in which the solid cylinder has a linear acceleration 4/3 times that of the hollow cylinder. This article describes an extreme version of this apparatus with a rolling object that has an acceleration more than 25 times that of an object of identical mass and rolling radius. This apparatus would be suitable as a lecture demonstration or as an intermediate-level laboratory project.
