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

Why are there so many moments of inertia for a given section? That is, i come across moments about the origin, x-axis, y-axis, centroid, xy-axis...etc... What are the differences? are there typical applications?

Please point me in the correct direction

Thanks in advance, any help is greatly appreciated
