Re: Radius of Gyration

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Richard,
You can consider the radius of gyration (we usually call it radius of
inertia) as the distance from a given body (i.e. section) axis to a
material point where you could concentrate all matter of the section
so that the said point would rotate about the said axis with the same
inertia as your full section.

Regards,
Alex
