Spider hardness houses have nothing to do with Boukaotha only

Spider hardness houses have nothing to do with Boukaotha only


Durability houses spider does not come back to only weaved silk, In the event of a shock allow her intention to abandon a limited part to keep the bulk might be a source of inspiration for engineers, according to a new study.The researchers explain in the journal Nature »British scientific, the combination« allow the spider to the restoration of the network, rather than rebuilt note that the construction of a house, or a network requires a lot of energy can not spider made at any time.
Have long known silk Beslaptha and durability but other advantages in a spider's web was still 'unknown', in the words of Marcus boiler values ​​on this research from the Massachusetts Institute of Technology in the United States.
A team of researchers based surveillance operations on the ground and computer simulations analyzing the structure of a spider's web and their response to various pressures, such as the fall of a small branch or a storm.
The Male Marcus boiler Yarns cobweb is «more durable than steel compared with a weight.
Consists spider homes located in parks and garages of several kinds of silk are two important aspects of the integration of the two threaded colloidal composition rubber bolts from the middle to the parties that allow capture prey and solid silk wire, which starts from the center of the network.
Silk plays these wires characterized by its solid composition and flexible key role in the specification of the mechanical advantages of the whole House.
In the event of any significant pressure, interact entire network, but every type of yarn reduces impact in their own way.
Whatever the type of thread that is subject to considerable mechanical pressure is the only one who stops and maintained the rest of the network, the researchers explain.
And contribute to the proteins that make up the silk in the shock absorber before frictions lead to rupture of the network.
