Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to derive the moment of inertia for a long rod with a point-weight on one end (the rod rotates through its midpoint). Could anyone offer any help? I know the formula for the rod is normally (1/2)ML^2, but I'm not sure how the weight on one end alters that.

Thanks!
