I was a village chief in a primitive society

Chapter 517: He actually has such great knowledge! (2 more please customize)

The sun's rays slowly fall on the surface of the Orbital Tribe, in a large wooden house by the river.

Long Zheng frowned and kept looking at the drawing in his hand. His face was so close that he almost pressed his face against it.

The big wooden house was built very large, and its appearance was not much different from an ordinary wooden house.

The main difference is that there is a separate wooden cabin that extends out, which is where the ship is placed. Moreover, this wooden cabin is relatively close to the river, and its appearance is the same as the shipyard on the other side of the earth.

This was specially built for Long, so that he could study shipbuilding with peace of mind inside.

And being so far away, the tribesmen would not disturb him, and the shipbuilding matter would not be known to others so quickly.

Moreover, there are many advantages to having a shipyard next to a big river. The built ship can then be pushed directly into the water.

He blinked his eyes and thought, and murmured to himself:"Why do you do this? What is the reason for doing this?"

He has been like this these days, and he has been studying it since he got the shipbuilding blueprints.

I sleep very little every day, eat in a hurry, and concentrate on the drawings.

And the more I looked at it, the more addicted I became. I was obsessed with the shipbuilding blueprint.

Even though I couldn’t understand many of them at first, I still enjoyed reading them, and after reading them for a long time, I could analyze the reasons myself.

He hasn't started building ships yet, but has focused all his attention on research.

I thought about getting some insights first, so that when building the ship, I don’t have to keep looking at it and studying it, but I can build it step by step without having to stop all the time.

"Witchcraft stuff is really good stuff, but it’s really not easy to study it at all."Long said to himself.

He loved this feeling so much. It was much more interesting than building a raft. Building that thing didn't require much brainpower at all, as long as you had skills.

Anyway, those rafts are all You can only go to sea once, so you don’t need to make it too fancy.

"But why should we erect this pole at this step? It looks ugly and bulky."Long scratched the back of his head.

He didn't understand much of the structure of this ship. He couldn't figure out why it was like this here and why it was like this there. It was as complicated as deciphering.

"Why is it upturned here? Wouldn't that look weird? And it’s not easy to make, right?"Long started to scratch his head with both hands. This was really difficult.

Without looking away from the drawing, he reached out and blindly looked for the water glass on the table, threw one in and started drinking.

"It seems that I still need to ask the witch. Only he can understand, so I won’t waste my time."Long murmured to himself after drinking the water.

He felt that if he continued to study like this, he didn't know how long he would have to study.

Thinking of this, he stood up and took the drawings with him, preparing to go to Yong'an Building to find Su. Bai.

After all, I have been studying this drawing for a long time, and I am about to start building the ship.

"Tap tap tap......"

Before he had taken two steps, the wooden door was opened, and a figure appeared in front of him.

"How's the research going? Do you have any clues?"Su Bai asked directly.

He came back from the wooden shed in the morning and happened to pass by the wooden house where Long Shipbuilding was built. He walked in to see how far the progress was.

He thought about asking the other party if there was anything he didn't understand, and then took advantage of the opportunity. Take this opportunity to explain it to the other party.

"Wu, I just have something to ask you about. There are several things I can't understand."Long said immediately.

He was a little flattered when he suddenly saw the arrival of the witch, so he immediately expressed his confusion. He was very serious when he said it, and he didn't care whether he would be called stupid. Anyway, he just said what he wanted.

"The reason for erecting a pole in the middle of the hull is to make the sail, and the boat needs to use the force generated by each side of the sail to move in the windward direction."

Su Bai nodded while listening, and continued to explain patiently:"The positive force on the windward side and the negative force on the leeward side combine to form a resultant force. Both forces act in the same direction."

A sailboat must have sails. A sailboat is a ship that uses wind power to move forward. It is an ancient water vehicle after boats and rafts. It has a history of more than 5,000 years on the earth.

Since this is the first time to build a ship, That's why Su Bai gave the other party the drawings of the sailboat. This kind of ship would be easier to build than other ships.

"It turns out that this thing is used to use the power of the wind. Now I understand."Long had a look of realization on his face. Now he regrets that he disliked this thing at first. At first, he felt that this thing was redundant and bulky and of no use, but he didn't expect it to be of such great use.

"As for the reason why the bow of the ship should be made into a triangle as you mentioned, it is for better advancement."

Su Bai pointed to the bow on the drawing and continued to explain:"The purpose of a ship with this structure is to maintain balance. Because the sea is very windy and wavey, a flat-bottomed ship can easily roll over and sink. The pointed bow can Reduce the resistance of water during navigation so that your progress will not be too slow

"I see, Wu, you are really smart."Long said in shock. He didn't expect that there were so many tricks in it. It's really incredible.

"Is there anything else you don’t understand?"Su Bai wanted to solve the other party's doubts at once, so that he could speed up the shipbuilding process.

"Witch, why is there this thing in the middle?"It can be said that there are many things that I don't understand.

"This is the keel. The keel is usually the first part of the hull to be built. The laying of the keel is one of the most important things in the shipbuilding process."

Su Bai took a pen and drew on the drawing, and continued:"In addition to bearing load, the keel also plays a role in hydrodynamics. It expands the side area of ​​the ship, increases the parallel impedance of the ship in the water, and prevents crosswinds. turn"

"Hydrodynamics?"Long frowned, the expression on his face looked very confused.

"Because this is especially important for sailing against the wind. In a sailboat, the keel will be supported by the diagonal braces in the middle or on the side of the frame. The keel also plays an important role in stabilizing the weight of the ship, reducing the tilt or reverse rotation of the ship. In short, this is The most important part of the ship."Su Bai explained seriously.

He explained to the other party very clearly and clearly, making sure that the other party did not make mistakes, otherwise the ship would easily disintegrate during the voyage.

"Wu, is this thing so important? Good thing I asked you."Long breathed a sigh of relief.

He never thought that there was such a great knowledge in shipbuilding. He really learned a lesson..........................................
