My problem is trying to calculate the moment of inertia for a rod with two weights on the each end (like the type weightlifters lift) turning in a horizontal plane with a wire fixed to the middle of the rod.(adsbygoogle = window.adsbygoogle || []).push({});

How do you calculate this? I suppose it could be seen as two cylinders, one small radius big thickness, one large radius small thickness, but how do i sum these together and how do i calculate this.

Thanks.
