Find balance point of weight on a rod : Calder sculpture type

[Coudamy]

Hello,
I want to determine the center balance of weight with different density suspended to a rod.
I can’t achieve it on Kangaroo.
Herei is a picture and a GH definition.

Thank you for the help.

You don’t need Kangaroo just to determine the center of mass - for that you can just average the centers for the different parts, weighted by their masses.
What are you trying to do?

There’s an example for a simulation of Calder like sculpture here:

In regular Rhino there is not need to separately average the centers of the different parts if the density is the same for all parts. Just use VolumeCentroid and select all the parts. The result will be the volume/mass averaged centroid.
