Abstract

Abstract:
The skeleton in human being represents the infrastructure of the whole body. God; the biggest designer ever; has considered all the miss use of human being to their body. This skeleton consists of sets of functional bone arrangements; linked and working together with the ligaments and muscles. These linkages represent sometime a cantilever; others simulate closed and open linkage systems. But in general, we confidently say that all structures are all stable, represent an equilibrium state when free or loaded. Even though; the day movements and hard duties carried out by man adds more and more over stresses to this skeleton. Many references have handled the case of stress distribution, stress waves propagation and attenuation in these mechanisms [7, 8], but none of them has reached the concrete evidence to assure the complete knowledge revealing the clue; how this sophisticated structure withstands overloading that some times exceeds what the similar solid metal structures resist.
