Most stable structure ?

Most stable structure ??

Hi
Could anyone tell me which/what is the most stable structure? And Why??

Thanks a lot

The most stable?

A really low, and heavy rectangle. Why? Because it has a really low center of gravity, and it cannot tip over easily.

But, the strongest?
A triangle. Why? Because when you put pressure on any part of the triangle, the pressure is divided up around the 3 sides, making the tensile strength increase greatly.

Depends what you mean by 'stable' and 'structure'.

 

[AzonicZeniths]

There is only one meaning for stable and structure, in this context:
Stable- –adjective, -bler, -blest.
not likely to fall or give way, as a structure, support, foundation, etc.; firm; steady.
Structure- –noun
mode of building, construction, or organization; arrangement of parts, elements, or constituents: a pyramidal structure.

The BCC crystal structure appears to have the lowest energy, IIRC. But, the various hexagonal packings are also quite stable.

On what level - subatomic, atomic, crystal/molecular, grain, product, building, moon, planet, star, . . . . ?

This isn't generally true. It applies to iron at room temperature, for example, but not to aluminum, copper, gold, silicon, carbon, tungsten...

Ahhh. Sorry about that post there, I did not consider the question in the right context.

a sphere?

ok
let me rephrase the question...
what is the most stable structure at sub atomic,atomic and marcoscopic level..??

 

[madmike159]

Well group 0/8 atoms such as neon have the most stable atoms because their outer shell is full of electrons and they can't react with other elements. I guess the strongest structure would be the lattis structure of diamond which has 4 bonds with other atoms I think.

What about Diamond? It's F[ace] C[entered] C[ubic], if I'm not wrong.

Isn't that pretty stable, considering its high melting temperature?
