Hi Guys - as we learn more and more about the science of wood and wood bats (why some break easier than others), it figures that the people who hold degrees in engineering (i.e. Mike Kravitz) would find the cause(s). Everybody wants to know why wood baseball bats sometimes break as they do (shatter in half).
We all know from playing the game, we usually break our own bats because we hit the ball off the end of the bat or in on the hands - pilot error - snap = kindling. But the sources of information I found regarding the "Slope of the Grain" is what the engineers have indicated as the culpable source of inferior wood bats. Here ya go check it out
