Engie bud (helped UW win solar glider competition few years ago) Sanjay Singh said steel is isotropic. Guess means same strength all ways?
Any way to seperate rounded-shape from flat-sheet strength?

BTW, sphere does well in sub app cuz no chance for local spot to 'dimple' - invert - from convex to concave- with same pressure all round. Spheres suffer from flexibility attemptign to redistribute load from localized impact in many apps. Leading to need for internal girdles to stiffen. Fuller ? did some work on integrated inner/outer domes to address, I think. FOund pic online. Making models - need 3d to hold to get it.

btw, anybody know if anyone ever expanded synergetics to fully replace calculus. C makes my brain hurt.
