We’ve never had a good reason to feature sports on our blog before. But as they say (or don’t say!): Baseball’s time has come. Here is a very interesting discussion that explores the swing weight of a bat. The author frames in the problem thus: how is it that two bats of the same weight (within 0.2 oz of each other when weighed on a precision scale) have different apparent swing weights while two other bats of different weights (3 oz between the two) seem to have the same swing weight? Baseball fans am sure will find this fascinating. The short answer is the distribution of mass and the moment-of-inertia this causes. For the complete answer refer to the above link!
