Into Unscientific

  Chapter 523 The first difficult step

  By the small forest.

   With the sound of this voice.

   Zheng Tao and the others were stunned for a moment.

  I saw that several people looked at each other in surprise, and after confirming that the person who spoke was not the standing people, they all turned their heads.

   locked eyes

  Xu Yun in a wheelchair.

  “.”

  Zheng Tao carefully sized up and down Xu Yun, who was similar to the second generation Tukage in "Hokage", before asking with some uncertainty:

   "Comrade, were you talking just now?"

  Xu Yun nodded and admitted:

   "That's right, it's me."

  “.”

  Zheng Tao was silent for a few seconds, and the expression on his face was inexplicably subtle:

   "Comrade, you just said."

   "Just put a few rectangular boxes on the top of the tower to avoid the shaking of the watchtower?"

  Xu Yun took some time to raise his neck this time, looked directly at Zheng Tao, and said:

   "That's right, but it's not right to fill these boxes full, it should be said to be half full of water."

   Confirming that he really did not experience auditory hallucinations, Zheng Tao's face was obviously a little surprised.

  He subconsciously looked towards the toolbox beside him, and tapped twice with his toes:

   "A box like this?"

   "Yes, but it's better to be taller, about half a meter high, and the bottom area should be about twice as large."

   Zheng Tao stopped talking.

   It's not that he understood Xu Yun's thoughts, but that after hearing Xu Yun's words, he became more and more at a loss.

To know.

  In order to solve the shaking of the watchtower, the construction sideline team has thought of many ways in the past two days, but none of them can solve the problem.

   Then into the mouth of this mummy, oh, just put a water tank on the top floor of the watchtower to prevent the tower from shaking?

  What the **** is this tmd?

  By the way, this comrade probably suffered from mental illness, right?

   Then he turned his probing gaze to Qiao Caihong, the meaning was obvious:

  【What is this person's background? 】

  Qiao Caihong glanced at Xu Yun, gently pulled Zheng Tao aside, and said in a low voice:

   "Brother Zheng, this comrade is called Han Li. He was rescued by Mr. Guo from a fire scene. He didn't work in our factory."

   "It is said that he is an international student of the Department of Mathematics of Cambridge University, and his background is extraordinary-this identity has been verified by Mr. Guo, so there is no problem."

   Zheng Tao was taken aback for a moment:

   "Guo Gong? Cambridge University?"

   Although due to the need for confidentiality, most people in Factory 221 use pseudonyms.

   There are even many examples of people who have worked in Factory 221 for more than ten years without even knowing the real identity of their roommates.

   But this is only a common situation at the employee level, and a well-known scholar like Lao Guo is another matter.

  Perhaps many workers don’t know Lao Guo’s real identity, but for college students like Zheng Tao who graduated from physics majors, Lao Guo’s identity is not a big secret.

  Lao Guo and Lu Guangda’s so-called “incognito” actually refers more to the secrecy of their whereabouts and whereabouts.

  So when I heard the word Guo Gong.

  Zheng Tao immediately understood that the person Qiao Caihong was talking about was Guo Youlai.

  Lao Guo's status and fame plus the signboard of Cambridge University

To know.

  Cambridge University's Cavendish Laboratory is currently the pinnacle of physics.

  If it is an international student returning from Cambridge.

  Maybe this seven-year-old young man named Han Li really has some special abilities?

  Think here.

  Zheng Tao looked at Xu Yun with doubts, but his attitude obviously wavered a lot.

   Then he exchanged glances with Zhang Gongding and Zhou Shaoping beside him, walked up to Xu Yun again, and asked him:

   "Hello, Comrade Han Li, right? My name is Zheng Tao, and I'm currently a small captain of the sideline construction team, with a job title."

   "I don't know if there is any physical or engineering theoretical support for the plan of the water tank you mentioned?"

  Looking at Zheng Tao with a more serious expression, Xu Yun couldn't help but quickly glanced at Qiao Caihong.

  Although I can't hear exactly what they talked about.

  However, Zheng Tao can have the effect of changing the face of Sichuan opera, and it can only be that the little nurse told the other party her 'identity'.

   In other words.

  I can start pulling the banner of Cambridge.

  So Xu Yun nodded quickly, and said firmly:

   "Of course, this is a theoretical field at the forefront of Cambridge University these years, and many top experts are conducting research on this theory."

   "Comrade, let me ask you a question first, do you know how to tell the difference between a raw egg and a boiled egg?"

   Zheng Tao blinked:

"ah?"

  He was planning to listen to Xu Yun's long speech, but unexpectedly, he just opened his mouth and said raw eggs and boiled eggs.

   Surprised.

  The whole person couldn't help being momentarily stunned.

   On the other hand, Zhou Shaoping was not fascinated, and quickly gave the answer:

   "I know, Comrade Han Li, you can tell the difference just by turning it—boiled eggs take a long time to turn, while raw eggs take a short time."

   "The answer is correct."

  Xu Yun looked up at the boss who wanted to introduce his granddaughter to him in the future, wondering if he should leave an indelible mark on him in this time and space, but he still asked normally:

   "Then why?"

  “.”

  Zhou Shaoping was a little startled by Xu Yun's gaze, but he still gave the answer honestly:

   "Because the shell of the boiled egg and the egg body, that is, the yolk and egg white, are basically fixed together."

   "The shell and egg of raw eggs are separated, and the shell and egg have relative motion during the rotation process, so the energy input by raw eggs is quickly consumed internally."

   "The internal energy consumption is fast, and the time for turning raw eggs is naturally shorter."

"bingo."

  Xu Yun wanted to snap his fingers subconsciously, but when he wanted to raise his hand, he realized that he couldn't move at all, so he could only sigh silently:

   "Very well, let's bring the topic back to reality."

   "Then the question is, if we regard the tower as the shell of an egg, how can we quickly dissipate the energy and stop the 'rotation' when the wind force is the same?"

   Hearing Xu Yun's words.

   Zhou Shaoping was taken aback for a moment.

   After a while.

   Zhou Shaoping was the first to react.

   He suddenly opened his eyes wide and stared at Xu Yun:

   "Comrade Han Li, what do you mean"

   "Can we add an unfixed yolk and egg white to the inside of this egg? Let the wind be consumed as soon as possible?"

  Xu Yun raised his eyebrows at him, and praised:

   "A child can be taught."

   Zhou Shaoping's breathing became short of breath.

  The example Xu Yun said was easy to understand, so soon, even Qiao Caihong roughly understood his thoughts.

   After half a minute.

   Zheng Tao, who had thoroughly thought about the feasibility, licked the chapped corners of his mouth, and asked Xu Yun:

   "Comrade Han Li, is there any official name for the plan you mentioned?"

  Xu Yun nodded to him:

   "Yes, it's called a tuned fluid damper."

  Students who like to play Yasuo should know it.

  The breeze felt on the ground reaches a height of hundreds of meters, and the wind speed can reach tens of meters per second.

   Waited until the height of 300 meters.

  The effect of the wind can make the skyscraper bear a force of 8 kilograms per square meter, causing the building to produce obvious vibration amplitude.

More seriously.

   After the wind bypasses the skyscraper, it creates an asymmetrical vortex behind the building.

  When the vortex falls off from both sides of the building alternately, a swipe to the left and a swipe to the right will act on the building with a periodic force, causing the building to vibrate.

   When the wind reaches a certain level, the building may resonate.

In this situation.

  The shaking of the building will become larger and larger, even .

   collapsed.

  So for a long time, people have designed many ways to avoid resonance to ensure the safety of buildings.

   For example, using asymmetric shapes, oblique network truss structures, etc.

  With the development of the construction industry.

   Around the end of the 1970s, an emerging technology with a far-reaching impact appeared in the construction industry.

That is.

   Damper.

  The earliest damper was a large mass that moved like a pendulum when the building swayed in the wind.

  The wind transmits energy to the building, and the building transmits energy to the mass block, and the mass block will shake in the opposite direction to the building.

  The hydraulic cylinder between the mass block and the building converts machinery into heat and releases it through friction, so the stability of the building is maintained.

  This technology appeared relatively late, let alone when it was introduced into China.

  The concept of domestic dampers will really enter the public eye and be widely disseminated, probably around July 2021.

  At that time, the typhoon and fireworks hit Shanghai, and the central building, known as the tallest building in China, opened the wind and typhoon protection measures.

   Among them, the most famous is the giant damper known as the "Eye of Magic City".

  This damper consists of a 1,000-ton mass and slings. It resonates with the main structure and can reduce the shaking of the building.

   On the day when the fireworks hit Modu.

   This entry even occupied the top search list for a long time, and the second is Wang Feng's new song.

   Another data that can reflect that the damper is an emerging technology is the application scenario of the damper:

   Even in 2021.

  There are only two skyscrapers equipped with giant dampers in the entire magic city, namely the Central Tower and the World Financial Center, and there is not even one in Yangcheng.

   At that time, a stalk appeared on the Internet.

   It is said that there are no dampers because there are more black people in Yangcheng.

  Ahem, let’s get down to business.

   Actually.

   In addition to the late development.

   There are also many types of dampers.

  For example, it can be divided into several types such as mass tuned damper, tuned liquid damper, viscous damper and so on.

  Among them, tuned liquid dampers are common in low-rise buildings. For example, many communities on the 20th and 30th floors will use tuned liquid dampers.

   In the liquid damper.

  Liquid flow will produce dissipation, that is, the momentum will be transferred to the liquid body through viscous resistance, and then the vibration energy will be dissipated, thereby reducing the vibration amplitude of the structure.

Of course.

  The fluid mechanics of this era is far from being as mature as later generations.

   Therefore, in terms of interpretation, Xu Yun chose simpler examples, that is, reincarnated eggs and boiled eggs to explain.

   And the other side.

   Zheng Tao and others were completely shocked and lost in thought.

  College students these days are not as bad as later generations, especially high-achieving students who graduated from science and engineering majors like Zheng Tao, whose thinking ability is the ceiling among their peers.

  After Xu Yun mentioned this, they quickly reproduced the relevant scene in their minds.

   So fast.

  Zheng Tao and Zhou Shaoping looked at each other again, and each of them saw a meaning in each other's eyes:

like

   Has a door?

  At least with their thinking ability, they really can't think of reasons to refute.

  Think here.

  Zheng Tao couldn't help but took another deep breath, turned around and asked Xu Yun:

   "Comrade Han Li, thank you very much for your valuable suggestion. I will report this plan to the team leader now. Maybe it will be of great help."

   "As for Comrade Han Li, are you waiting for news here, or are you going to the watchtower with us?"

  Of course Xu Yun didn’t want to miss this occasion, so he immediately replied after hearing the words:

   "I'll go and have a look too."

  Zheng Tao has no objection to this.

  So the few people quickly changed direction, and walked towards the watchtower together with Lao Bai and his team members.

  The location of the watchtower is not far from the grove, and within a few minutes, everyone arrived at the watchtower.

   Right now.

   There are about a dozen workers gathered by the watchtower, most of them are shirtless, and they are grunting along the bottom of the watchtower to apply cement.

no way.

  In the current period, if you want to strengthen the building against earthquakes, the basic idea is to accumulate volume.

   In fact, not only now, even in 2023, don't many Paradox players also like to do this kind of thing?

   Then Zheng Tao walked up to a little old man who looked like the person in charge, gestured to him and spoke.

  The little old man was about fifty, thin and small, with gray temples and a little felt hat on his head.

  After hearing what Zheng Tao said.

  He was slightly taken aback for a moment, then turned to look at Xu Yun, and soon fell into deep thought.

   After a while.

  I saw him shaking his head, but under Zheng Tao's repeated insistence, his expression began to become hesitant again.

after awhile.

  The little old man reluctantly nodded, and waved his big hand lightly, as if he had made some decision.

  Zheng Tao stood at attention excitedly, beckoning others to get busy.

  The cuboid water tank may not be easy to find in later generations, but it is not a rare thing for the 221 factory today:

  Different from the Bosten freshwater lake adjacent to the Malan Base, the Qinghai Lake next to the Jinyintan Base is an authentic saltwater lake.

   Therefore, the water inside the base often needs to use some equipment for external supply and transportation.

  Pipes are the foundation, and various water tanks are often used as auxiliary.

   So fast.

  Zheng Tao and others found a flat rectangular iron water tank that met Xu Yun's requirements.

   Then they hoisted the empty water tank to the top of the watchtower tower through the pulley block, and sent several buckets to the top in turn, and filled them with water one by one.

   Throughout the process.

  The rest of the people were either helping, or watching the show with arms folded, and they even turned their attention to Xu Yun from time to time.

   More than twenty minutes later.

  Xu Yun noticed that the 'Old White' who seemed a bit stingy bent down and fiddled a few times, and went up to the watchtower with an instrument.

   Coincidentally.

   Not long after Lao Bai went upstairs.

   A gust of wind blew from the south of the tower.

  Hulala~~~~

  The strong wind swept in with a large amount of sand and gravel, the sky was covered with gray, and the wind force was at least level eight or above by visual inspection.

  See this scenario.

  The workers on the site ran to the watchtower or behind the vehicle to hide from the wind. Zhou Shaoping, Zhang Gongding and Qiao Caihong fought against the wind and sand and pushed Xu Yun's wheelchair behind a stone stack.

  Tear—

  The gust of wind blew up a piece of cloth covering hanging on the watchtower in an instant. The cloth covering spun a few times in the air, and then disappeared far away from everyone's sight.

   After a while,

  The dust just stopped the noise.

   Wait for the wind and sand to disappear.

   Heads poked out around the watchtower like a game of whack-a-mole.

  After shaking the sand off his body.

  Everyone cast their eyes on .

  The top of the watchtower.

   Then, half a minute later.

  Under the gaze of everyone on the ground, Zheng Tao suddenly poked his head out from the top of the tower, and shouted excitedly:

   "Teacher Yao! The measurement result of our horizontal instrument is completely normal, and the tower is not shaking!"

   "Water Tank."

   "Really useful!!"

   I don’t know why I had the same dream two days in a row, dreaming that Tyson died.
