Let you teach, you play games with the worst class?

If they can finish this thing within a month, it will be considered smooth.

......

At the same time, in the live broadcast room, most of the netizens also fell into thinking.

If this matter is put on them, can they solve it?

Wooden boat, it doesn't look difficult, but it doesn't seem to be so simple...

"To be reasonable, is it possible to stagger the boards and connect them directly with nails, as long as the nails are long enough and the force is dispersed enough, the problem shouldn't be a big deal.

Isn't that what medieval ships are all about in those movies? "

Soon, some netizens put forward their opinions, and then they were denied by others the next moment.

"You also said that it is a movie, or the Middle Ages."

"Medieval ships, even if they are 50 meters larger, are almost the same. If they are smaller and properly handled, they may still be able to withstand wind and waves."

"But Class Nine is now building a giant ship of 150 meters. After scaling up, any small problem will become a big problem, just like they built the keel before."

"Do you really think nails are still useful?"

"Besides, what they want to build is a treasure ship of the Ming Dynasty after all. The power of the Ming Dynasty at sea was the number one in the world back then, so the craftsmanship must be different."

"So, mortise and tenon is probably the ultimate way out..."

"But that thing must be leaking. Even if the middle of the hull is glued, it will definitely fall off during the violent shaking."

"Damn, this is not what a human being should do. The first step was finally successful. Why is the second step so difficult?"

"It's not difficult, Teacher Ren will bring the students to do it?"

"It can't be done. My head hurts from thinking about it. At some point, I can't find any information at all. There is no other way for this thing except to flip through the book."

"Why do you suddenly have a little bit of sympathy for Class Nine?

Children of the same age, who would encounter difficulties like them? "

"It's the same, the same high school seniors, who can be as happy as them?"

"Energy conservation, honesty don't lie to me..."

Soon, in the live broadcast room, netizens gradually changed the topic.

In the directing room, the judges couldn't give any comments to Class Nine at this time.

In this matter, they are not professional, so they can only watch the live broadcast of other players and say a few words.

He Bing, who was on the side, was a little melancholy.

Now that the ratings of Class Nine are high, why do you say a few words? !

If this goes on, it will be very difficult for me!

And the same difficult thing is the director team.

At this point, they were already thinking about whether to urgently find a shipbuilder to serve as a judge.

Otherwise, how should Class [-] discuss the topic after this?

Or, lucky enough to find a captain?

In case the ninth class really goes to sea, the captain can also use it, right?

Gradually, the idea of ​​the director team became more and more serious.

......

At this time, Class Nine.

After a long period of thinking and brainstorming alone.

They still decided to seek help from their own cheap teachers.

Although this looks very dish.

But it's better than running around like a headless chicken.

Just now, they have thought of many ways.

What glue, module assembly, gap filling, all kinds of brain holes have been thought out by them.

But after a series of simulations, all were abandoned by them.

Even if they don't use mortise and tenon joints, those gaps will still exist. This is an inherent defect in the material, and has little direct relationship with the production method.

Make them quite bald.

They couldn't figure out at all how the ancients managed to be waterproof for a long time when the hull was full of gaps and the keel had to be connected to the hull.

This is simply black technology.

As for this question, Ren Yan just casually glanced at her group of 'stupid students'.

Slowly speaking in an extremely ordinary tone:

"Since one layer can't be done, can't you make two layers?"

"Two floors?!"

Everyone in Class Nine was taken aback, and felt even more confused in an instant.

Make the hull into two layers, can this thing really be realized?

So how heavy is this weight? !

And, most importantly...

Are two layers really waterproof?

Won't the gaps that should exist still exist?

In the next moment, the facial features of everyone in Class Nine crowded together again.

They felt that their teacher was using a rather teasing tone, and said to them like Master Ma:

"Teasing you~~"

Ma De, I really want him to know what the wrath of a man is!

Class Nine secretly thought...

Chapter 284 Ma De, where is the sail! 【Seek full order】

Seeing this, Ren Yan immediately gave the other party a big white eye.

"Have you ever played with a paper boat?"

"A piece of paper can be waterproof even if it is folded many times, let alone wood."

"and..."

"Everything you could build before was called keels and ribs..."

"You have seen the kind of biological bones that grow on the outside, not the shell, of course they have to grow inside the body~"

"Can you use your brain?"

"You mean, the outline of the ship needs to be wrapped? Include all the keels and ribs?" Wang Bo asked in surprise.

Ren Yan nodded: "Not all, at least the spine of your main keel should be exposed, it is the main body of everything and the main heaviness, it cannot be wrapped inside the hull."

"But the other ribs, they are the support of the ship's 'flesh', and the flesh needs to grow on them."

"And what about flesh and blood? A layer of cutin and skin is needed. Only in this way can we truly prevent all foreign objects."

"So, the ancient ship's hull is not a single layer at all."

"Sometimes, the naming of an object can fully understand its usefulness. You should think about it more, don't just see the image in front of you, but discover the inner part."

"But... the structure of the two-layer hull can really be floated by sea water and supported by the keel?"

"They're not a heavyweight at all."

"And, even if there are two layers, wouldn't the gaps that should exist still exist?"

"The boat made of paper is a whole. Strictly speaking, it has no gaps."

In the end, Xu Kai still asked this question in confusion.

He really couldn't figure out how to do it.

Hearing this, Ren Yan fortunately sat up from the chair, picked up a scattered piece of wood with bark on it, and carefully buckled it up:

"Did you see that something as rough as the bark can prevent water and protect the trunk inside it well? The reason is that there is a layer of connection between the bark and the trunk."

"Just like our skin, since it can't be directly connected, why not add a layer."

"A layer of something that primarily prevents moisture loss."

"Haven't you done this before?"

"You mean gum?" Xu Kai was taken aback.

"Otherwise?" Ren Yan threw away the wood casually.

"The two-story structure has a specific waterproof layer in the middle, and the inside and outside are connected with mortise and tenon joints to leave a certain interlaced space. Finally, it is painted. Wouldn't it be possible to completely isolate the seawater?"

"After that, as long as regular inspections and repairs are implemented, it will be able to operate for a long time."

"Everything in the universe, so many wonderful things, any point can open up your thinking, don't always think about solving problems in a predetermined way."

"As for the weight issue you just mentioned, it depends on your material selection and calculation."

"As long as the whole is conserved, it is impossible for the ship to sink."

After all, Ren Yan threw herself into the recliner again, flipped through her mobile phone and began to search for opportunities for sailing trials.

By the way, I asked about the specific time of the invitation sent out when I first arrived at the warehouse.

He really feels a little bit stretched by himself now.

Now it is only the second step of shipbuilding, and Class Nine has encountered so many problems.

I can only give an overview at most by myself, and if I really want to go deep into the details, I will definitely not be able to do it.

and....

Thinking of this, Ren Yan glanced at the full warehouse.

Now this warehouse is really a bit small...

As for everyone in Class Nine, they were slightly dazed.

Looking at the wood thrown down by Ren Yan's bark, he was dazed.

Such a hull problem, can it really be solved with such a piece of wood?

They always feel a little unbelievable, but after simulating it in their minds, they feel that this method is really feasible.

The principles involved are simple and straightforward.

It's just comparing a ship to a creature, and the hull to skin.

And what they have to do is to add this metaphor strictly according to the appearance of the 'creature' in their brains, layer by layer, so that it will gradually become a 'living creature'.

This suddenly gave them a sense of 'creating' rather than simply building.

At this moment, the students in Class Nine completely changed the preconceived notions in their minds, and more ingenious ideas gradually brewed in their hearts.

They know how to build this hull!

After thanking Ren Yan, Class Nine returned to work again.

According to the hint given by Ren Yan just now, a new job was started.

First, there is the issue of material.

Since two layers are required and special bonding is required in the middle, the choice of material must be as light and tough as possible, while taking into account the degree of adhesion to the gum.

Among various experiments and practices, the surveying and mapping team finally chose pine wood.

This thing is known as an evergreen tree, and its own toughness is excellent. At the same time, because of its unique material, the wood is compact and light, and the combination with the gum is not bad.

It is the most perfect material in wood at present.
