Chapter 1084: The First Suspension Bridge in Daqing (Page 1/1)

It is exactly as Qin Hongmian said, if Shi Yuan builds this bridge, it will be much easier for them to go out, but in this way, it means giving up defense......

There was such a perception obviously because she didn't know what kind of rope bridge Shi Yuan planned to build. How could a "sinister and cunning" person like Shi Yuan do such a foolish thing?

"Don't worry, it's just a temporary build, if only the Cotton Girl can find the exit in the clan hall...... Shall we just destroy this bridge? Shi Yuan said very indifferently, and then suddenly pulled the rope hanging on the pillar. After a moment of flipping of the column, the rope fell to the ground......

According to Shi Yuan's instructions, there were a total of six thick ropes, and the thin ropes were not counted, and soon this was before the one-legged road with the support of everyone in the village.

Because the six-heel main rope is too thick, it is a little difficult to get it to the outside of the village and then pull it by turning the grinding plate. At the moment, it can only rely on the brute strength of Qiao Cannon and others outside the village!

In fact, Shi Yuan's idea is very simple, plus the ropes that have been pulled over, a total of seven main ropes, three parallel to make noodles, straightened and paved with wooden boards. The remaining four are used to make "columns", two on each side, adjust the distance, straighten the smooth, and then tie the string on both sides to form a triangular net, so as to stabilize the bearing capacity of the bridge deck.

Because of the large number of people, this originally very time-consuming and labor-intensive project was completed in the time of two incense sticks. Of course, now there is only the prototype of a bridge, that is to say, the time of two incense sticks, so many people have just adjusted a total of seven main ropes.

That's a lot of speed......

Only now did everyone gradually understand Shi Yuan's idea. However, it is still a little difficult to see anything from these seven main ropes completely!

In fact, many rope bridges in Daqing are such structures. So far, Shi Yuan's idea has not made people realize any surprises, but soon they will see the extraordinary things about the rope bridge that Shi Yuan wants to build......

After pulling the main rope, Shi Yuan told everyone to stop. On the one hand, after a series of physical labor, everyone, including himself, needed to breathe, and on the other hand, he needed to calculate it carefully.

The seven main ropes are fixed to the pillars erected on both sides of the river and the trunks of trees made of local materials. Let's talk about the degree of solidity...... In fact, this degree is enough, as long as the wooden board is laid and the triangulation net is tied, the problem will definitely not be very big. But Shi Yuan was still a little uneasy! Because what he wanted was not a rope bridge that could only cross one or two people, and it was still rickety and scary, he needed a bridge that was stable enough and balanced enough.

The cognition of the discipline of mechanics in Daqing is very limited, and there was no overall discipline or system before, but in the book "Introduction to Physics" edited by Shi Yuan, it was established and formed a special discipline. And now in the Baiye College in Jinling City, and even in the entire Jinling City, there are many people who know the saying "gravity".

No matter how many people can accept these theories and sayings that sound very shocking to the world now, it is always a good thing that such a concept can be understood by everyone.

"What are you doing?" Seeing that Shi Yuan was gesturing on the ground for a long time, but did not speak, Qin Hongmian couldn't help but ask curiously.

Shi Yuan's calculation is actually at the end, this is not a complicated algorithm, but there are many units of measurement that he needs to study carefully.

"That's it!" Shi Yuan, who was not in a hurry to answer Qin Hongmian's question, did not clap his hands and stand up until he finished the last item, and replied to Qin Hongmian.

"So what now?" Qin Hongmian didn't have much interest in what Shi Yuan was gesturing on the ground for half a day, she just saw that Liuli on the other side was already waiting impatiently...... So after Shi Yuan stood up, she hurriedly asked.

"What you have to do now, you may need Cotton Tree Girl and Liuli to do it!" Shi Yuan replied to Qin Hongmian: "I need to tie a rope to the main rope in the middle and the main rope on both sides, it doesn't need to be too thick, only the general thickness is enough." ”

"Tie the rope?" Qin Hongmian looked at the seven main ropes in front of him, and if he wanted to tie the rope in the middle, someone had to grab the rope and walk over to do it. It's not that hard, but the key is ...... What is Shi Yuan's purpose in doing this?

"After tying the rope to the main rope, tie the tied rope to the trunk on both sides, and in this way, you can build a suspension bridge!"

"Drawbridge?" This word was still a little unfamiliar to Qin Hongmian, so he frowned.

"This ...... Cotton Girl, just do what I say! However, the position of this rope must be the same on both sides, a total of eight, tied to the main rope of two feet three inches, four feet one inch...... I don't know if you can do it? ”

"What's so hard about that? You just have to explain it to Miss Liuli. ”

At this time, Liuli, who was sulking angrily, didn't speak for a long time after seeing Shi Yuan let everyone finish pulling the main rope, and he also understood that things might not be so simple. But even if she understood, she was just a little impatient......

"What are you doing here? You don't need to do it here! Seeing Shi Yuan coming over, she didn't want to speak. But she couldn't stand the special situation now, and she couldn't help but ask after all.

"Xiao Liuli, now I need you to tie this rope to this main rope, and the positions are tied to the ......" But Shi Yuan, who was already familiar with her attitude, didn't say much, so he got straight to business.

On the one hand, Liuli was born before Shi Yuan and looked down on her, but on the other hand, she was eager to prove her "worth...... So after listening to what Shi Yuan wanted her to do, she began to contradict her. However, her ambivalence did not last long, and after Shi Yuan handed her the rope in his hand, she could be regarded as acquiescing......

Working on these seven main ropes is undoubtedly very dangerous for ordinary people, but for Liuli and Qin Hongmian, it is much simpler!

It is also thanks to the fact that although the ravine is bottomless, it is not wide. Otherwise, you may need to erect two pillars in the middle! Of course, if that were the case, it would be a big project.
