Hello all. I'm trying to find the equation for combined Center of Gravity (CoG) when you combine two objects with different weight. I know how to find the centroid, which is what the CoG would be if both objects were the same weight. But what about two objects with different weight? For an example, I have two square with the area of x^2. Square A weights 40lbs and square B weights 600lbs. If I combined both squares, where would the CoG be? I'm assuming the equation has something to do with density, distance of CoG at a specific point, and area invovled. Thanks for the help!
