abstract = {The concept of the center of mass was used by Archimedes more than 2,400 years ago.¹ Much later Euler introduced another mass-related concept, that of the moment of inertia (see section A.9), which in turn suggested some very nice solutions of mathematical problems [BB]. Here I solve several other mathematical problems using the center of mass.Recall that the center of mass of a body is the body’s point of balance; the body suspended on that point is in equilibrium in any orientation. Full details can be found in the appendix (section A.8).As an interesting aside, we take it},
