Component Positions & CG

Where m_i is mass and (x_i, y_i) is position of each component.

CG is the average location of mass, weighted by each component. The balance point.

Lift point must be above CG to prevent tilting.

Divide into simple components and use weighted average.

Add Z coordinate: CG_z = Σ(mi×zi)/Σmi.

No, CG is fixed relative to the object.
