Sphere:
“Aiming of the compressional loading of a short column into the neutral or central-most axis of the column provides the greatest columnar resistance to the compressing because, being the neutral axis, it brings in the most mass coherence to oppose the force. To make a local and symmetrical island of compression from a short column which axial loading has progressively twisted and expanded at girth, into a cigar shape, you have to load it additionally along its neutral axis until the ever-fattening cigar shape squashes into a sphere. In the spherical condition, for the first and only time, any axis of a spherical structure is neutral-- or, ergo, in its most effective resistant-to-compression attitude. It is everywhere at highest compression and tension resisting capability to withstand any forces acting upon it.”
