Li Fuzhao brought out the questions he heard from the Bei family's father and son as they were.

In these years, knowledge has been specialized, and if everyone is chatting with a wine glass, it can really be endless, but once it comes to professional knowledge, there is still a gap between them.

It's like Li Fuzhao and I.M. Pei, if the topic is living in the United States, you can talk about this for half an hour, and someone will pee in half an hour, and you are old!

But if you talk about architecture, Li Fuzhao can only point to the end, otherwise it will become a one-sided education, how can a person with such a temper stand this... It's like the Xiangshan Hotel or something, he doesn't want to say more.

Fortunately, the high-level concept provided by Li Yiming made him very happy to pretend to be forced to put a straw between the two floors, and the result was no less than putting a "high-rise" aura on himself-

Didn't you see that the father and son of the Bei family began to ponder?

But if he stays any longer, then he will be confused, and it is better to leave a good impression than to wait until then to touch his head and go out......

This project is definitely not small!

Others may think that Li Yiming may not be doing this in Xiangjiang, but Li Fuzhao knows very well that even if Li Yiming's ultimate goal is not in Xiangjiang, he will definitely have to open a test field here.

And definitely with his "rough" method

Question one, how do you open it?

Question 2, how rough is it, and can the Li family handle it?

After taking those few steps just now, he had a rough plan in his mind, and now he wants to take a standard answer from Li Yiming to compare it and see how much he has grown.

"The pipe is not strong? Li Yiming picked up a piece of paper and shook it.

Sure enough, Li Fuzhao hurriedly stepped forward to take it, and his eyes were already glued to the top: "This is the pipe?"

He saw that the pipe drawn on the paper was not round, the longest part of the section was marked with three meters eight, the height was one meter five, and the drawing was millimeters, so he automatically converted it, and by the way, he imagined something in his mind...... Not......

The tube looks like a slender peanut, no... Pork kidney!

No, to be precise, the tube is flat, with a cross-section like a kidney... Cashew!

How do you make a good pipe like this?

What did you say about heart bypass before, but now that you have a waist out, is it possible that Li Yiming, who will go to the heart and kidneys, will be able to heal?

"What's so particular about this kidney-shaped design?" Li Fuzhao asked modestly, of course he wouldn't say anything about how this resembles a waist.

Li Yiming naturally explained: "There are two things, one is that the interior can be divided into two paths, and second, this shape can reduce weight." ”

Divided into two ways, Li Fuzhao understood it as soon as he heard it, but... Weight loss?

Why does this shape reduce weight?

Comrade Newton, hurry up and explain!

Li Fuzhao glanced at Li Jianguo specifically.

Li Jianguo smiled and didn't say anything, he also looked at this picture with him, and he didn't know why he lost weight.

Li Fuzhao leaned in front of the table: "Why can I lose weight?"

"This is a single tube, do you see the circle on the cross-section? The front is a protrusion, the other end is a pit, and there are completely transparent holes, and the steel cable is put together in the middle and put together one by one, and then the screws are screwed, which is very firm. ”

Li Yiming took another piece of paper and drew the appearance of the pipe between the two floors: "Look, the downward side is recessed, the wind is strong between the buildings, there is a lift, do you understand the load reduction?"

"Deloading?"

"It means that the two ends are lighter than the original weight, if this is made of engineering plastics, a single pipe is about 50 kilograms, one meter is 100 kilograms, ten meters is a ton, 30 meters long pipe weighs three tons, the greater the wind speed, the lighter it is. You can understand that this is a wing!" Li Yiming said impatiently.

Li Fuzhao half opened his mouth, can it still be like this?

"Wing ......"

Li Yiming looked at Li Fuzhao and frowned: "Didn't I tell you Bernoulli's principle before?"

Li Fuzhao suddenly, the corners of his forehead began to sweat again, but he remembered.

It was yesterday that Li Yiming put himself in to see things, and then the little devil was interested in the rubber strip.

After Li Yiming's explanation, the Li family's uncle and nephew knew that it was indeed not simple:

This rubber strip can not only be used for elevator anti-pinching, but also has a role as a key accessory for the bottom of the car vacuum slot, because of the Bernoulli effect, the car will raise dust, so much ash is not only dug out of the tires.

So then the Li family was assigned a task about the size of a fly cage - to renovate all the cars in Xiangjiang and install this vacuum trough.

It's good now, everything else is going on vigorously, but there's no news about this.

At this moment, Li Yiming mentioned this Bernoulli again, as if he was beating himself intentionally or unintentionally.

"I haven't ...... about the car change It's not that I deliberately neglect it, because this kind of thing actually has to come forward, after all, with an identity like Lei Juekun, it's not enough to send a junior to say hello. ”

Li Fuzhao was a little flustered, worried that Li Yiming would be unhappy again: "Anyway, it's easier to install something under the car, you can wait for the product to come out." Now there is a pile of things, I haven't even had the time to deal with this one, he still has a theater on hand, and I want to deal with it together......"

Li Yiming shook his head instead: "This is not in a hurry, the time is not right." ”

Li Fuzhao couldn't help but feel a cold neck: "What time?" He immediately thought of Li Yiming's habitual smashing of plates, is there something big wrong with these cars?

Li Yiming looked at him: "I'll tell you, but not now!"

That's a chance to smash the plate!

Li Fuzhao nodded with anticipation, and looked at the paper design again: "This is an assembled one, a section is only fifty centimeters, won't it be short?"

"It's not easy to do when it's long, the mold is too big, this is enough, in fact, this one uses four pieces to put together a tube, and the mold only uses two. ”

Li Fuzhao picked up the paper and listened with his ears pricked up while looking at the picture.

Li Yiming doesn't mark everything on the map, and this is the shape of the patent application.

Li Fuzhao imagined what these pipes would look like after they were put on the steel cable and then buckled up, but it was very simple.

In fact, in the end, it was still a long tube, but it did feel a lot stronger, he raised his eyes to look at Li Jianguo, who was sitting on the side and listened carefully, and seized the opportunity to smile: "Jianguo, this reminds me of the cold ...... of the Dadu Bridge and the iron rope you said."

Li Jianguo nodded thoughtfully, many places in the mainland are actually iron chain bridges, and the bridges are about three or four meters wide.

This kind of bridge is very dangerous for a long time, and there are not many people walking, and he has heard of several accidents that caused people to overturn because many people watched dragon boat races on the bridge.

Li Yiming took a pen and typed a few arrows on the paper: "The wind speed between the high-rise buildings will be greater, although the direction is more chaotic, but it is normal to follow the direction of the road, do you understand the relative movement?"

"I see, three tons doesn't seem to weigh much, let alone less than three tons. Li Fuzhao raised his head and thought about it, after all, he is also highly educated and highly intelligent, although his main business is finance, but he understands basic physics knowledge.

The pipe is oblique, which is equivalent to more than sixty percent of the weight should be on the low floor, compared to the cement and steel bars in the building, this weight is really nothing.

"Of course, the quality of the tube is good, but because it is actually much lighter than expected in the air, there are steel cables in it, and there is no need to worry about falling off if it breaks physically.

Considering that it is not empty that people will pass inside, one person is counted as 60 kilograms, in fact, it is calculated that there are several people at the same time at the most dangerous time. This kind of structure can be more than 40 people at the same time, this is my calculation, and I have to test the data after I make it. ”

Li Yiming put the paper in Li Fuzhao's hand.

"When is it most dangerous?" Li Fuzhao asked subconsciously.

"The building is on fire, and people have to evacuate, right? There is a case of kidnapping with guns in the building, and people must also evacuate quickly, this is a dangerous situation!" Li Yiming said a few words, "At that time, it was not a person who passed slowly, but threw it inside, and if you lose it here or there, you have to vacate the exit immediately!"

Li Fuzhao nodded violently: "Yes!"
