Sphere
RBF Definitions
". . . As a condition of the sphere for the first time, any axis is a neutral axis, in the spherical condition, it has aptitude in any direction to withdraw the forces on it; it is not surprising that ball bearings become the most effective compression members ever designed by man. I am not surprised to find more or less spherical planets in the heavens tensionally cohered, compression at its most effective."
