People are in the United States: the starting point is full of intelligence

Chapter 175 Hair
Eitlake manipulated the holographic screen to replay the impact of the vortex engulfing the car, saying:
"The sand man can manipulate the sand like his arm, and can manipulate every grain of sand at will. You are looking at this, the power of the vortex sand comes from other sand."

Seeing that Coulson still didn't understand, Itlake constructed a physical model of a rope in an ideal state from the database, pulled one end, and let it shake on the screen.

This virtual rope shakes out an "S"-shaped wavy line, spreading to infinity, Eitlake said:

"If the sandman's control over the sand is like a snake's control over the body, then the vortex's control over the sand is like the rope I shake.

Snakes can change any shape autonomously, and any segment of the body has muscles, which is the drive control system; but the rope only has power at the starting point, and subsequent waves cannot be finely controlled. "

Coulson listened to Itlake comparing the desert vortex to a dead object, which meant that the work of S.H.I.E.L.D. Small objects gobble it up, and that's simply not possible if he doesn't have the ability to finely control each grain of sand."

Itlake shook his head and said: "Colson, I understand what you mean, your simple idea is described by physical theory as Archimedes' principle, that is, in the absence of external force manipulation, an object with a density greater than sand sinks A sandy bottom, objects that are less dense than sand float on the surface.

But Archimedes' principle applies to stationary liquids and gases, sand is not a liquid, because of the existence of friction, they can even be regarded as rigid bodies until the maximum static friction is overcome. "

Coulson wanted to say something again, but he didn't have enough theoretical knowledge, so he couldn't express his intuitive and simple feeling about physical effects in words. Itlake said:
"Colson, I know what you want to say. When the sand flows, it has properties similar to flowing liquid, which is the so-called fluid."

Coulson said: "Yes, that's what I meant! Quicksand cannot be consciously controlled, then it will only obey the Archimedes principle of nature, and things that are lighter than it cannot be swallowed by it! "

Itlake shook his head again, and said: "I just said that a stationary liquid obeys the Archimedes' principle, but a flowing liquid does not obey the Archimedes' principle.

Sand cannot be approximated as a liquid in a static state, and it can be approximated as a liquid in a flowing state, but it can only be approximated as a flowing liquid, not a static liquid.

Fluid mechanics is much more complicated. In addition to Archimedes' principle, it also obeys Bernoulli's principle, that is, where the flow velocity is faster, the pressure is lower; while the flow velocity is slower, the pressure is higher. "

Coulson observed the vortex on the screen, and it was obvious that the flow velocity in the center of the vortex was faster, and it was the faster flow velocity in the center that drove the surrounding sand to move, and asked: "Is it really fast? , that is to say, the pressure in the fast place in the middle is low, while the pressure in the slow place around is high...

By the way, does high or low pressure have any effect on what we're talking about? "

"Of course there is. Imagine a balloon full of air. The pressure inside it is significantly higher than the atmosphere. If you poke on its surface, the gas will be ejected from the balloon into the atmosphere.

That is to say, the side with high pressure has high pressure, and it will push the object to the direction with low pressure; another description is also true, and the side with low pressure will generate a corresponding "pull force", which will pull the object over. "

Coulson suddenly realized, clapped his hands and said: "Oh! In other words, it is Bernoulli's principle that overcomes Archimedes' principle and pulls the object from the periphery to the center...

No, this still doesn't explain why it sank? "

Itlake sighed, saying that a smart head doesn't grow hair, but Coulson is an exception. It seems that he has to work harder to get rid of the current Mediterranean haircut as his boss's hairstyle, maybe he can follow him in the future On his own thinking, said:

"This shows that the fastest flow is not on the surface of the center of the vortex, but directly below the center of the vortex, there is an area with faster flow and lower pressure."

This time Coulson was completely stunned, but he was also a little disappointed, and said, "In other words, this vortex is just a pool of dead objects, without consciousness?"

Itlake shook his head again, and said: "I just said that these sands are dead objects and cannot be controlled one by one, and I didn't say that there are no conscious creatures here, otherwise the vortex will not move when you make a movement Get up and stand still after you leave."

Tony, who had been listening to the conversation between the two, finally understood what Itlake said, and made a metaphor in a simple way, saying:
"That is to say, the desert vortex is not the body of that conscious body. If it is a metaphor, the vortex is just the 'hair' of that body, which will move when he shakes his head, but it cannot be really controlled by him.

Itlake, is that so? "

Itlake nodded, and the two looked at Coulson in unison. Coulson scratched his bald forehead and said:
"Of course I understand!
If you make this comparison with the bureau chief, he may not understand, because he is very unfamiliar with the concept of hair, but I still have some. "

"Without further delay, since we have made such a guess, let's confirm it." Itlake said:

"There should be a power source deep in the center of the vortex, which is the reason for the rotation of the desert, and it is also the place with the fastest speed and the lowest pressure, and it is also where the powerful creature is.

I suggest that Mr. Stark transform the steel armor, transform the flame injection device into a shield component, and then use the Bernoulli principle that exists in the vortex to send the steel armor to the position of the 'power source', From this we can have direct contact with his body. "

Coulson regained hope. It seems that it was indeed the right thing to invite Italek. It took less than half a day to come here and he had already come up with a feasible investigation plan. You know, before he came, all Scientists are all stuck in the stage of being at a loss, circling around the vortex.

Both Itlake and Tony were action-oriented, and the latter dropped a set of steel armor from the sky, and the two began to transform it.

The task of this steel battle armor is to drill holes in the sandy bottom, and it is difficult to move an inch underground with a flamethrowing device, so it needs to be transformed into a tunnel-type power device.

There are only Tony and Itlake in the lab, and Itlake no longer shy away from using Hannah's reactor and Spider-Man's superpowers.

He covered the black spider web in front of his eyes, drove the Hannah reactor into the spider silk at the fingertips, and fired lasers to weld the mecha.
