calculating the center of gravity of several object/material

calculating the center of gravity of several object/material

I wanted to know the final center of gravity with different materials for my project radio-control (helicopter) I can assume that his interest in another balanced system

written in VB (C# gave me a lot of problems :()

in my heli project I have moved ~1.5mm battery (electronics/wire is calculated approximately)

You can find the center of mass using something like this:

All objects must be closed solids so that the volume calculations are correct. If one object is partially inside another, use boolean subtraction.

thank you, your calculation is simpler than mine:), both give the same result

I updated the example

It would be great if I could use your script in my academic project. What kind of variable is hidden under carbon, metal etc. is it specific weight of a material?

I know this is a really old thread, but I'm a grasshopper newbie looking to find the center of mass of a funny shaped room with different objects inside. I have a known weight for the objects and room (floor, walls, ceiling etc) and can model everything as solids.

Is there a way to assign weights to different objects and calculate the center of mass for the group of objects?
