摘要:

We propose some simple experiments to measure moments of inertia of certain physical pendula having high and low symmetry. Periods of oscillation, mass, and distance of the pivot from the center of mass are used to measureICMfor: (a) the “floating eagle,” an intriguing toy, and (b) a rectangular plate. Values ofICMobtained from measurements about different parallel axes may be checked for consistency.
