» » Spider Web: stronger than steel.


The strength of a spider's web is not a mere object of science fiction.

One day I was on my porch and saw a spider web, the spider not was there, because the web was (quite big). I wondered what was the size of that spider. Well I started to clean up very slowly, when it appeared a very interesting curiosity and perhaps inĂștel of which is the strength of a spider's web.
Immediately the TGM (The Grill Man) went to the web, and more an important public service useless. After many pages visited, I selected only two (it is enough!) And where are the texts:


Not coincidentally, one of the greatest superhero film, Spider-Man, can move at high speed through the streets of New York holding only tiny strands that hang in the buildings. The strands of protein that form the intricate web that spiders capture their prey, are five times stronger than steel wire of the same diameter and can be stretched to four times its length without breaking. Imagine then what Spider-Man would be able to do if you had been bitten by the spider Achaearanea tepidariorum American, the kind that weaves the web toughest of all.


Although a wire is invisible to the naked eye to be very thin (0.15 micro), it is so strong that it can, in a network with minimum density, stop a beetle flying at high speed. Experts believe that if the spider web that had the wires with the same thickness of a pencil could stop a Boeing 747 in flight. The explanation for a filament is so strong that the more force the spider uses to pull the wire during manufacture, will become stronger after hardened.

Spider's web is 100 times more sticky than previously thought.

The droplets that leave the spider has a sticky adhesive strength 100 times greater than previously thought, according to a study published in Nature Communications.
Researchers at the American University of Akron found that the substance composed of glycoproteins without behaves as a solid compound with both viscous and elastic properties and has a great strength.
Scientists also discovered that this substance acts differently depending on the strength and speed that the prey tries to escape. If he tries to escape slowly, it acts as a rubber, more resistant, which allows time for the spider to capture prey. The more intense the pull, the stronger are the adhesive properties, which allows even faster animals, such as flying insects become trapped.
