The main component of spider webs is protein, which will decompose quickly when exposed to fire, so spider webs are afraid of fire. The spider web has good elasticity and a small wind-bearing area, so it is not afraid of wind. The surface of the spider web has grease to make it waterproof.

In life, why are spider webs so strong? appeared, and we have to consider the fact that it appeared. I have also thought about this issue carefully and have been thinking about it day and night.
With these questions in mind, let's examine why cobwebs are so strong. In life, why are spider webs so strong? appeared, and we have to consider the fact that it appeared.
Seneca once mentioned that life is like a fable, and its value is not in terms of length and shortness, but in content. This makes me think deeply. We all know that as long as it makes sense, then it has to be carefully considered.
Marton said a philosophical saying, strong faith, can make ordinary people do amazing things. This inspires me. It has been mentioned in Africa that even the most spiritual people cannot see their backs.
This seems to answer my doubts. This fact means a lot to me, and I believe it has some meaning to the world. We have to face a very embarrassing fact, and that is,
-
The spider's web is reflected in its silk, because the spider is made of a special structure in the process of spinning silk, as well as the direction and structure of the spider when it is built.
-
Only viscosity, not toughness.
If it were solid, Spider-Man would break one day while swinging.

We also see spiders in our daily lives, but many people are actually more afraid of this creature. Spiders have a lot of silk pulp in their stomachs, and spiders have small holes at the end of their tails, so spiders usually build webs and then use the webs to catch insects. Is it true that spider silk is actually very strong, and spider silk is stronger than steel wire?
Spiders may not be carefully observed in daily life, and spiders are actually beneficial animals. Spider silk is a kind of viscous protein silk thread spit out by spiders, spider silk has high elasticity and strength because of irregular and regular protein molecular chains, so human beings have used spider silk for a long time, spider silk is used as a crosshair in telescope devices. Therefore, spider silk is very strong, and once it is stained with flying insects, then these insects are largely unable to break free.
Compared with steel wire, the physical and chemical properties of spider silk still have obvious advantages, and in terms of mechanical strength, the fiber and strength of spider silk are very high. The toughness of spider silk is better than that of ordinary fibers sold on the market, so spider silk fibers also have a strong application prospect in national defense. But if you want to get spider silk from natural spiders, then this production is still very limited, but now with the development of technology, many people have obtained spider silk through genetic synthesis.
According to scientists' research experiments, the rope composed of spider silk is tougher than stainless steel of the same thickness, spider silk can withstand five times heavier weight than steel bars, although spider silk looks very thin, but spider silk is very elastic, because spider silk is composed of proteins, so you can take as long as you want, so spider silk has a wide range of applications. Spider silk can now be made by a certain method, so it is very versatile.
-
This is true because spider silk has irregular chains of protein molecules in it, which makes spider silk very elastic and not easy to break.
-
It's true, because spider silk has proteins and acids in it, so it has better elasticity and strength.
-
Not really, because our wire doesn't break when we touch it with our fingers, but spider silk breaks when we touch it with our fingers.

Darwin's barking spider (Caerostris darwini) found on the island of Madagascar
The web is the toughest ever known, with a tensile strength of 520 megajoules per square meter – twice the strength of all the aforementioned webs. Darwin's barking spider's web is also the largest – up to 30 square feet (square metres) – large enough to stretch from one bank of the river to the other side.
-
The composition of spider webs is protein fibers. The toughness is large, if the steel wire is made so thin according to the proportion of spider silk, it can be seen that the toughness of the steel wire is far less good than the toughness of spider silk.
Spider web is a spider spinning silk woven into the web, generally to weave the web as a means of hunting spiders like to weave webs in the face of the well-lit place, in order to ensure that the prey due to the light reflection visual confusion, so that the spider is easier to enjoy the food, some people see the spider all day on the web thinking that the spider web is the spider's nest, the spider's hiding place is actually a very small cave, or on the roof, the reference value of the spider web is extremely high, some people have made the spider silk into body armor, the toughness of the spider silk is 4-6 times that of the alloy steel cable, Moreover, spider silk occupies an important position in the field of artificial **.

Just like an egg, if you hold it hard, it will be forced, and it will disperse the force, and the same is true of the spider web.
-
In short, the mesh structure supports it enough to bear much heavier than itself.
-
Because it is not strong, the mosquitoes and flies will run away.

No, it won't. I guess one of the reasons is that most of the time it's spent sitting in the break room of the net**, and the silk there is completely non-sticky. However, this statement cannot be justified, it cannot sit in the net for the rest of its life, and sometimes, the prey is stuck on the edge of the net.
It must rush over and release the filaments to entangle it, and how can it keep itself from getting stuck as it passes through its sticky web? Is there something on its feet that allows it to glide easily over the sticky web? Did it put some kind of oil on the feet?
Because we all know that oiling is the best way to make surface objects non-sticky. To prove my suspicions, I cut off a leg from a living spider, soaked it in carbon disulfide for an hour, and carefully washed the leg with a brush that had also been soaked in carbon disulfide. Carbon disulfide dissolves fat, so if there is oil on the legs, the wash will be completely washed off.
Now I'm putting this leg in the web again, and it's firmly glued! From this we know that the spider has a special layer of "oil" on its body, so that it can move freely around the web without getting stuck. But it doesn't want to stop at the sticky spiral ring, because this "oil" is finite and will be used less and less.
So it spends most of its time in its own "break room". From the experiments, we know that the spirals in the spider web absorb water very easily. Because of this, when the air suddenly becomes humid, they stop weaving nets and only make shelves, spokes and "lounges", because these are not affected by moisture.
As for the spiral part, they will not be easily done, because if it absorbs too much water, it will not be able to absorb enough water and dissolve the tide in the future. With this spiral, the web does not become dry and easy to break in extremely hot weather, because it absorbs as much moisture as possible from the air to maintain its elasticity and increase its viscosity. What birdcatcher can compare artistically and technically to a spider when it comes to making webs?
And spiders weave such delicate webs just to catch a small bug! It's a bit overkill! At the same time, the spider is also a passionate and active worker.
I have calculated that it takes about twenty yards of silk for each web made by the horned spider, and thirty yards for the finer silk, and my neighbor had to mend his web almost every night for two months. Thus, during this period, it had to extract this tubular, elastic filament from its petite and thin body. We can't help but wonder, how can its small body produce so much silk?
How can it roll these filaments into tubes, and how can it fill them with slime? How can it sometimes make ordinary silk, sometimes cloud-like silk flowers to cushion the nest, and finally make black ribbons to decorate the nest? These questions have been circling in my mind and have left me with no clues.
It heralds a rebirth and a new level.
Spider webs are woven from the silk spun of some species of spiders, which are used to catch insects, small vertebrates, etc. for food, or to build nests for living. Spiders can sense the vibrations of their prey when they collide or become trapped in a spider's web; After finishing their webs, spiders wait on or near the web for their prey to fall into the trap. >>>More
Scientists have found that spiders generally have 6-8 textile webs at the end of their abdomen, and each textile has hundreds of spouts - the silk is discharged through the spouts. Spiders have glands with different functions corresponding to each spinn, and each gland produces a different raw material of silk thread, thus weaving both sticky and non-sticky silk threads. Scientists have found that the radial skeletal filaments (longitudinal filaments) on the spider web are very strong, but not sticky. >>>More
The following are common spider species:
