Radius of Gyration for Generic Polygons

Click For Summary
SUMMARY

The discussion focuses on calculating the radius of gyration for a generic convex polygon with a constant density and a known centroid axis of rotation. The user seeks an established equation for this calculation. It is suggested to triangulate the polygon into two parts separated by the axis and compute the moment of inertia for each part to derive the radius of gyration. Relevant resources include Wikipedia's page on radius of gyration and a specific blog post on calculating the moment of inertia for convex polygons.

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?
