I need to calculate the radius of gyration for a generic, convex polygon, where the density is constant, the axis of rotation is the centroid (which is known), and the positions of the vertices are known. Does such an equation exist?

http://lab.polygonal.de/2006/08/17/c...onvexpolygon/ I would triangulate the two polygon parts separated by the axis individually. And then workout the inertial moment around that axis.
