I am looking at the Crisco study (Med Sci Sports Excer 34:1675-1684) comparing wood and metal bats and trying to repeat their calculation for the "moment of inertia" without success. Please help me as I am not able to derive their numbers using the calculation MOI = mass (bat weight) * distance (bat length) [squared] .

Where did I fall off the truck?

Thanks!
