Hey Y'all, There is a mistake in the final number for the MOI calc. It should be closer to 41.18x10^6. The math is correct, but be sure to change that final number when you get to that point. Sorry about that!

how you arrive to 109.14x10^6 moment of inertia? I tried to compute it and I get 41186590.92. tnx.

Thanks for pointing that out, I may have made an error when inputting in my calculator. Your answer is correct. Thanks for double checking!
