Walking in, it’s the dock room.

"What are those trunks for?" Xiao Zan asked, pointing to the base of the dock room.

Chen Zheng glanced and replied: "These are keel piers and side piers on the bottom plate, which are used to support the ship."

Before anyone else could ask questions, Chen Zheng continued to introduce: "The front of the dock is opposite to the dock mouth. I designed a semicircle, which looks relatively wide."

"What is this for?" Xiao Zan looked like he asked if he didn't understand.

"The space here is actually part of the docking room." Chen Zhengdao, "Here, we can disassemble, assemble, and paint the surface of the ship, which is also done here."

Xiao Zan listened very seriously, but unfortunately, he couldn't understand.

Because there are no ships built now and no ships come here to rest, it is hard for Xiao Zan to imagine just based on Chen Zheng's description.

Chen Zheng also saw Xiao Zan's confusion. It was really hard to understand just by saying this, but his task was to introduce it to the craftsmen.

Whether you understand or not, that's your business.

When Li Shuang saw that if she explained this, it would be of no use at all. The key point was that Shui Xiaozan seemed to be getting more and more confused.

However, it seemed that they were lucky. At this moment, a shout came from outside. It turned out that it was a sea boat and was about to go into the dock for repair.

When Chen Zheng saw it, he quickly took everyone out of the dock room and came to the second floor of the dock.

At this time, workers in the dock opened the irrigation facilities at the dock pier and began to fill the dock with water. Not long after, the water levels in the dock and outside the dock were already equal.

At this time, the dock door was opened and a sea boat slowly drove into the dock.

Liu Bin saw it very carefully and asked, "Master Chen, there are no paddlings on the boat, how did he come in?"

Li Shuang knew this answer and wanted to show off, so she took a step forward and said, "This question is good. Have you seen the ropes that lead the sea boat?"

Liu Bin nodded and said, "I saw it, but I didn't see anyone pulling it."

Li Shuang smiled slightly and said, "Look at the end of the rope, there is only a small mouth, but there is a different world inside."

"What's inside?" Liu Bin was almost anxious, "You said that."

"Tsk tsk tsk tsk, why are you anxious? I'm talking." Li Shuang was a little impatient. "There is a wooden winch in there. You just need to turn the winch to pull the rope forward, and the sea boat was naturally pulled in."

"How many people are needed? This sea boat is not small." Liu Bin said, estimating the number of people inside.

Li Shuang put his hands behind her back and said, "As you can see, there is a rope on one side, that is, a person on the other side."

"Impossible!" Liu Bin said decisively, "How could two people pull such a large sea boat?"

Li Shuang became even more impatient and said, "The winch is very light to rotate. Take the people here for example. Except for the useless Yang Xiaoping, everyone else can turn!"

Yang Xiaoping: “…”

Yang Xiaoping felt a little wronged when he didn't mess with anyone, and was shot for no reason. However, when he saw Prince Xiao Zan listening with relish, he knew that this was not the time to interrupt.

However, Yang Xiaoping silently remembered this account in his heart. When the time is ripe, it is not too late to take revenge.

But Liu Bin still didn't believe it, shook his head and said, "How could there be such a winch? This is a sea ship!"

Li Shuang only knew the reason, but didn't know why, so she had to say, "This winch was made by Brother Chen, so it's naturally light and brisk. If you don't believe it, forget it."

Liu Bin frowned and asked, "Do you think the winch was made by Master Chen?"

"Yes!" Li Shuang nodded, "If you don't believe it, go and try it yourself."

"My heart!" Liu Bin said directly, "Master Chen's skills are so skillful and superb. Even if I tell me that the winch will automatically pull the ship forward, I believe it!"

Li Shuang was very unhappy when she heard this and said, "Master Liu, I didn't expect you to look honest and honest. In fact, you can play with this double standard very easily. Why do you believe it if you say that Brother Chen is made, and you don't believe it if others do it?"

Liu Bin was honest and nodded directly, saying, "So far, Master Chen is the craftsman I admire the most. I can't believe the skills of others!"

"You!" Li Shuang was speechless, "You can really argue."

Chen Zheng didn't expect that Liu Bin would become his little fan. Oh no, it should be his little fan. He looks much bigger than himself.

Since people admire him so much, Chen Zheng felt it was necessary to tell him the principle of the winch.

Chen Zheng walked up to Liu Bin and said to him: "Actually, the principle of the winch is very simple, I can tell you."

Liu Bin was overjoyed and said, "I wish to listen carefully."

Other craftsmen, including Xiao Zan, all raised their ears and wanted to hear what Chen Zheng said about the principle of the winch.

When Chen Zheng saw that so many people were interested, he told them about his design principles.

The principle of saving effort in winch is very simple, it is just a transmission principle. Large gears drive pinions and change the magnitude of the force through torque transmission.

However, the less effort used does not mean that the work is done. According to the law of conservation of energy, if you want to move the sea ship into the dock, the work you do is certain and cannot be reduced.

Chen got this inspiration from the variable speed bike of his time. If he wanted to win, he would shift the chain to the gear wheel, but in this way, he would have less distance to pedal a circle of the bike.

Although it takes a lot more effort to move the chain to the small plate, the distance you can move forward several times that of the chain on the large plate after pedaling a bicycle.

How to choose depends on the needs of the bicycle riders.

After explaining this simple truth, many experienced craftsmen understood it, but Xiao Zan, who had no life experience, did not understand it.

Chen Zheng was a little helpless, so he said to Xiao Zan: "Brother Xiao, otherwise, you can try it yourself?"

Yang Xiaoping felt that this was an opportunity, so he jumped out and shouted: "Chen Zheng, you are arrogant and actually asked our young master to work for you. What should we blame!"

However, as soon as Yang Xiaoping finished speaking, he was kicked aside by Xiao Zan and said, "Get out of the way, don't disturb me in school!"

When Li Shuang saw it, she quickly said, "Brother Xiao's desire for knowledge is really touched. Let's do this, let's bring this sea boat in one by one?"

Xiao Zan was very interesting and said, "It's so wonderful, Brother Li, please!"

"Brother Xiao, please!"
