Tension is comprehensively without law. Compression tends toward arcs of decreasing radius. Tension tends toward arcs of increasing radius. Compressions are plural. Tension is singular.
Compression is time.
Tension is eternity. Compression is specifically directional. Compression is inherently partial. Tension is inherently total. 644.00 Limitless Ratios of Tension 644.01 I adopted as a working hypothesis that there is a limit to slenderness ratio of the girth diameter of a compression member in respect to its longitudinal axis and that there is no limit to the slenderness ratio of structures dominated by tensional components.
