Stabiele lichamen

dmx

Hallo

Ik kwam deze vraag tegen:

"Welke lichamen zijn automatisch stabiel?"

Op internet heb ik hier echter niets over gevonden.

Iemand die weet waarop er gedoelt?

Zou het gaan over platonische lichamen?

Maar "waarom", geen idee..

Alvast bedankt!

Waar kwam je die vraag tegen?

Slides van meetkunde:

Platonische & Archimedische lichamen.

Maar er staat geen uitleg bij

Klinkt allemaal nogal vaag. Misschien heb je hier iets aan:

It's also interesting that Plato describes the "1,1,sqrt(2)" triangle as the most "stable", and the most likely to hold its shape, thus accounting for the inert and unchanging quality of the solid elements. He didn't elaborate on his criterion for "stability", although we can imagine that he had in mind the more nearly equal lengths of the edges, being closer to equilibrium. On the other hand, this would suggest that the equilateral triangle (which is the face of Plato's "less stable" elements) was highly stable. Plato made no mention of the fact that the cube is actually the only UNstable Platonic solid,

in the sense of rigidity of its edge structure. In addition, the cube is the only Platonic solid that is NOT an equilibrium

configuration for its vertices on the surface of a sphere with respect to an inverse-square repulsion. Nevertheless, the idea of stability of the sub-atomic structure of solid is somewhat akin to modern accounts of the stability of inert elements.
