Measure Radius of Gyration of a Mass In Siemens NX

In Siemens NX is easy to calculate radius of gyration of mass in one part or assembly part, the definition of

 Radius Gyration are

The Radius of Gyration of a Mass about a given axis is a distance k from the axis. At this distance k an equivalent mass is thought of as a Point Mass. The moment of inertia of this Point Mass about the original axis is unchanged.
The radius of gyration (r) about a given axis can be computed in terms of the mass moment of inertia I around that axis, and the total mass m;

or

I is a scalar, and is not the moment of inertia tensor , (efunda and wiki)

Measure EG in Siemens NX

to begin measure bodies in Siemens NX choose Analysis in your toolbar, then select Measure Bodies, see picture below for detail

 after you select Measure Bodies a dialog box will appear, then you must select all solid body or part that you want to measure

 by default calculation of volume will be selected, but we can change to other calculation, like mass, surface area, weight and of course radius of gyration,  we will see new axis with symbol Zp,Xp and Yp, yest, there is position of radius of gyration, exact position also can see on box that appear, it's distance from the center
