The following URL shows the power relation between stress and
strain for a brittle material.

Because the stress-strain curve of a brittle material is virtually
a straight line it is important to stress (no pun intended )
that this stress-strain curv

Ugh... let me see if I can ignore that ugly mental
image for a while... and present a more relevant image
for those trying to develop 'virtual' x-ray vision
Let us approach the elimination of force via the concept of strain
energy since this is a well known concept familiar to all engineers.
Energy (work) = stress x strain W = p.e (1)
Elastic modulus = stress/strain E = p/e (2)
Looking back through the "...upon the clouds of heaven..."

Since Dr Storms has implicitly raised the subject of
chemical bonds by asking, "How does strain provide
the glue that creates a solid from atoms?", I would
like now to deal with "bonds" on the macro scale.

And dust is not sucked up by vacuum cleaners. Solids are held together
at the first scale of scrutiny by the difference in stress of the Beta

Interesting idea, Frank. Now let me ask some questions. How does strain
deflect the path of an electron? How does strain accelerate a rocket? How
does strain keep us attracted to the earth? How does strain provide the glue
that creates a solid from atoms?
