Propriedades biomecânicas do osso
(ou Lições de conduta)
Bone must be stiff and able to resist deformation, making loading possible.
Bone must also be flexible to adsorb energy by deforming: to shorten and widen when compressed, and to lengthen and narrow in tension without cracking.
If bone is too brittle, the energy imposed during loading will be released by structural failure: initially by development of microcracks and then by complete fracture.
If bone is too flexible and deforms beyond its peak strain, it will also crack and fracture.

It reminds me Frank-Starling.
But regarding the heart.
And everyone knows the heart is more poetic ;)
