"You said you can't figure out the length and curvature of the keel?"

Ren Yan looked at Wang Bo and others in front of him with half-squinted eyes, and subconsciously yawned.

Wang Bo and others nodded:

"Yes, Teacher Ren."

"We simply can't find wood that long."

"We don't have wood that is five meters long on the arc, and including the arc part, we conservatively estimate that it will take about 6 meters to be usable."

"So, you are stuck?"

Ren Yan covered her mouth and yawned again, then she woke up slightly.

"Yes, teacher, so do you think there is anything we can do?"

Wang Bo and others looked at Ren Yan expectantly.

Ren Yan did not answer directly, but instead asked the group of students in front of him:

"Before you came to me, have you ever thought of a solution?"

"have!"

Wang Yu nodded and spoke out the previous ideas of Team Nine and others:

"Length-wise, we can't handle it at all."

"But in terms of curvature, although there seems to be a gap of about one meter, if the overall volume of the wood is taken into account, it is not impossible to get another one."

"But the biggest problem with this is quality."

"Because the curvature is too high, the original toughness of the wood will be lost."

"And there is only a curvature of the keel, but there is still a big gap between it and the complete keel."

"We did a lot of research on the Internet and found that the keels used in ships are made of one piece of wood, and are integrated from the dragon head to the dragon's spine to the dragon's tail."

"But right now, we obviously can't do that."

After Wang Yu said this, the other students nodded in agreement.

Ren Yan calmly changed her sitting position: "I still have some ideas."

"Did you check it on a certain website?"

Everyone nodded.

Ren Yan smiled slightly:

"I looked at it carefully at some point. There are only concepts about large wooden ships, and more manufacturing methods are all transformed from modern industry."

"The keel is basically made of cast steel, so naturally you can make it look whatever you want."

"But have you ever thought about it, if ancient shipbuilding was like modern times, would they really be able to find trees that can guarantee a minimum of 150 meters?"

"Even if the natural environment was very good in the past, trees of this height still push the limits, not to mention the use of suitable wood."

"Then how did the dragon bones be made in the Ming Dynasty?"

Wang Bo made a sound in surprise.

"Simple, splicing~" Ren Yan replied casually.

"Splicing?!" The students in Class 9 were all shocked:

"Teacher Ren, can that be strong?"

"Those ships have to sail in the sea. If they are really spliced ​​together, when a wave hits, the keels won't fall apart immediately?"

Students in Class 9 said they were unconvinced.

Not only them, but also netizens and judges didn’t quite believe it.

Even Ren Yan couldn't believe this at first.

But this is indeed true.

This bit of knowledge was recently obtained by Ren Yan through the 'search engine' built into his brain.

At first, he completely scorned this statement and thought it was a fantasy.

A wooden keel, still spliced.

As long as a big wave hits you, if you don't fall apart, you are considered to be extremely skilled.

until

He saw the ‘demo picture’ provided by the system.

In the picture, the waves hit the spliced ​​keel, but the spliced ​​keel unloads force due to the mutual fit between the splicing points. Although it looks extremely dangerous, it is actually as stable as an old dog.

As long as the wood quality is within the bearable range, no matter how big the waves are, it can withstand all waves.

Even because of the unique force-relieving method, this endurance range can be even larger.

On the other hand, look at another ‘demonstration picture of an integral wooden keel.’

Once the wave reaches its carrying capacity, it will suddenly break off in the middle.

Let Ren Yan have a good understanding of what it means to be too strong and easy to break.

At the same time, he also completely changed his ideas.

After thinking about it later, he gradually understood the reason for this phenomenon.

Now is the time to tell my students.

"Who told you that splicing won't be strong?"

Ren Yan looked at the students of Class 9 with great interest and smiled again:

“Think of you making tables, chairs and benches on the farm.”

"Think again about those ancient buildings in our Dragon Kingdom."

"You can often hear news about landslides in modern buildings, but have you ever heard about landslides in those ancient buildings?"

After saying that, Ren Yan waited for the student's answer.

Then the next moment, he was choked to death.

"Isn't it because there are so few ancient buildings that have survived to this day that experts have been maintaining them?"

"Moreover, if this kind of thing really happens, the guards will be held responsible. Who dares to really say it? Shouldn't it be handled privately?"

Classmate Ah Wei expressed his thoughts very straightforwardly.

The surrounding students looked over in admiration.

There aren't many guys with such a strong head these days.

Even Wang Yu, who was relatively stubborn, cast admiring glances at Ah Wei.

As for Ren Yan, after coughing twice, she sincerely praised Ah Wei.

"Don't talk like this when you go out in the future, you may get beaten easily."

Then, he forcefully changed the topic:

"I'm saying this to let you experience the spirit, you know?"

"Don't you understand what these words mean?"

Ren Yan asked again, and after a moment, Xia Yue tentatively answered:

"Teacher Ren, you mean the mortise and tenon structure?"

"That's right!" Ren Yan let out a long breath.

What a shame, finally someone realizes what I mean.

"All houses in the ancient Dragon Kingdom were supported by mortise and tenon structures."

"Like a giant figure, lying on the ground."

"And later on, some people did special research and replicas of the same ancient building were used for seismic testing."

"The results are also very gratifying. In the earthquake with the highest magnitude of 13, the ancient houses only moved a few inches without any damage."

"I remember telling you about this, why didn't you think of it?"

Ren Yan looked at the Class 9 students with some curiosity.

The students from Class 9 turned red:

"Well, haven't we been looking for ancient shipbuilding technology, so we haven't thought about it?"
