Live broadcast: Teach students to play Three Kingdoms at the beginning

Chapter 285 Made, 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 can build before is 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: "That's right."

"However, the keel is the shallowest wrapping. It is the overall support of the ship. If the wrapping is too tight, it will not be effective."

"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 guys done this before?"

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

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

"There is a two-story structure with 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.

As for the mortise and tenon that will be needed later.

The production team also came up with a new method, since the mortise and tenon of the keel cannot be used.

They simply started thinking directly with the way of thinking that Ren Yan had just taught.

Every mortise and tenon joint is joined with a small specially treated pin as much as possible, so that it can play a force-dissipating role while being precise connected.

They call it 'muscle'.

This kind of tendons will be spread throughout the inner and outer layers of the entire hull, and the force dissipation effect of one may not be seen, but if there are more of them, the effect will not be much worse than that of the keel.

This is a special structure that they racked their brains and finally came up with.

It looks like an ordinary ancient ship on the outside, but inside it is something different.

After some prototype tests, Class Nine believed that it would not be a big problem for the entire hull to bear a weight of [-] kilograms.

Xu Kai even recorded this structure completely in the shipbuilding sub-drawings,

Following the deduction calculations and realistic simulations of the whole Class Nine, although the hull of the ship still hasn't set up a plank, the progress is officially on the right track.

In the following time, they were all busy with the problem of the hull.

Although from time to time, new problems will be born.

But they turned their minds around completely, did not encounter any real difficulties, and were still proceeding in an orderly manner.

And in order to really pass the quality test, they have to conduct a test every time they complete the splicing of a piece of wood.

The most done is the waterproof test.

For this reason, they also specially made a large bucket of sea water.

Only when the newly installed wooden planks can withstand 21 splashes of sea water without any water leakage, will they consider this piece qualified.

And will be assigned a unique mark.

Of course, this kind of test is only under construction. After the first floor is built, they will conduct an overall test.

But then they will be in the sea, and they are full of anticipation.

I am also very fortunate that the warehouse rented by Mr. Ren has a seawater shipbuilding area on one side, otherwise it would be a problem to let a half-built ship go into the sea.

Days, in such a situation with a clear goal, two days have passed.

Two days later, the bottom warehouse with a height of about one meter on the first floor was completely taken care of by Class Nine.

It has been glued and painted, and the measures of waterproofing, moistureproofing and insectproofing have been fully implemented.

On the side of the shipbuilding area close to the sea, Class Nine laid out a large number of rolling logs, propped up their half-built ship from high to low, and pushed the ship that gave them their expectations forward with a sound of concerted efforts. nautical mile.

When the waves splashed, everyone felt a strong sense of accomplishment.

After about a month, the boat built by their Class Nine finally went to sea.

Although it can only be regarded as an embryo now, it can be called a ship after all.

Apart from this sense of accomplishment, the rest of Class Nine is just worrying.

Worried about whether the ship can really float on the ocean as they expected.

The rope used to secure the boat has been tied to a corner of the warehouse.

Amidst the tension and prayers of Class Nine, time passed by every minute.

Even netizens and judges have some different emotions in their hearts.

They want the ship to float steadily.

Even though some of them objected to Ren Yan's plan to 'go to sea' before, this is still the case now.

But at this moment, they really hope that the ship will succeed from the bottom of their hearts.

These days, they have witnessed the efforts of Class Nine, and they don't want this effort to be wasted.

Even this kind of effort will bring hidden dangers to the future. '

But they still hope, and they feel in their hearts that the efforts of these children in recent days are 'worthy' of such success.

As for going to sea, it is different from the current emotion.

In the parent group, the parents who often farted and chatted also fell silent.

A large number of 'digital' users flooded into the live broadcast.

The General Administration of Education and Ding Guoxiang were also watching this scene intently.

Everyone has a little bit of anticipation.

Ren Yan also stared at everything in front of her.

Time passed by every minute and every second, as if everyone was holding their breath.

The whole warehouse seemed unusually quiet.

One point, two points.
Five points, ten points.
There is still no sign of being soaked inside the ship.

It wasn't until 45 minutes later that Class Nine gave out an excited cry.

The whole warehouse immediately became noisy.

Many students hugged the classmate next to them and sucked hard.

Such a long time of hard work was not in vain after all!

45 minutes is the main time frame of their test.

At the same time, this time is also the peeling time they calculated for paint and gum to fail in seawater.

As long as there is still no water seepage after this time, it can show that there is no problem with their ships as a whole!

It seems to be infected by Class Nine.

All kinds of netizens and judges also sent out heartfelt smiles.

In the live broadcast room, various bullet screens of [Ninth Class Niubi] kept flashing.

In the studio, the judges were not stingy in their praise.

However, after boasting, they found that something seemed wrong.

Why is it so long, Ren Yan, a teacher, doesn't mean to be happy for a long time?

Instead, he looked at Class Nine with indescribable sympathy? '

'I guess, what's the situation? '

Everyone was startled, and looked carefully at the 'small half' ship on the screen again.

Immediately, their smiles stopped, and changed into an extremely tangled look.

Damn, this boat seems to be missing something.
No wonder it looks so awkward.
At this time, Class Nine followed Ren Yan's eyes and seemed to be aware of this problem.

They looked at each other with dejected and speechless expressions, and then looked at Xu Kai in unison.

"Made, where is the sail!!!"
