When a Woodpecker, pounding his beak in the trunk of a tree, brought upon him a force of 1.000G, capable of causing severe damage kraniogkefalikes. Yet he remains undaunted, and especially the sound work! Group of Chinese scientists, has decided to solve the mystery and find out how he manages to survive both blow ... head, beautiful bird!
Researchers from the University of Beiangk Beijing and Hong Kong Polytechnic University, studied how we just absorbed the vibrations caused by repetitive motion of the head of the woodpecker on the surface of the tree. Their conclusions were that the forces exerted as the Woodpecker beating their beak in the trunk of a speed of 6 m / s, reaching the 1.000 G (see video)! Using scanners, discovered the existence spongiform both parts of the skull bones and the beak of the woodpecker, which apparently are a special shock absorber, protecting the birds from their injuries. Now if you wonder why an entire team worked on this issue, to explain how they feel how impressive their findings could lead experts to design safer helmets - which will protect against head injuries more effectively!
