"Judge Liu, if it is suitable for equipment and sufficient conditions, one person can pull up an object of 10,000 stones, but this bulky equipment cannot do it. The greater the weight, the stronger the friction, and the effective weight will decrease. The real effective weight that can pull up 600 stones may be only 200 stones, and a hundred dozen stones, and the effective weight that can pull up 100 stones will be increased to fifty stones and sixty stones."

In fact, it’s useless to say Song Jiu.

"Xiaojiulangjun, where did you learn this knowledge?"

"Simple. There are some records in the "Mo Jing" that are also used by the people. For example, the wells in the arid areas in the north are very deep. People use winches to fetch water, or winches used to raise anchors on boats. The two principles are the same. Buddhism says that looking at a mountain is a mountain, looking at a mountain is not a mountain, looking at a mountain or a mountain. When you see a winch, you don't think about it. The first layer of looking at a mountain is a mountain. If you think about it, there are some truths in the middle, not as simple as the surface, that is, the second level of realm, looking at a mountain is not a mountain. If you figure out the principle, it is looking at a mountain is a mountain, and the highest level of realm."

It's just a waste of time.

“When will it come in handy?”

Liu Yi was not sure. Maybe it was Song Jiu who was fooling him, maybe it was true, it was a mule or a horse, and he had to come out and walk around to know the truth or false.

"At least four or five days, it must be corrected after repeated trial and error."

The high platform on the river bank cannot be tested, the technology must be kept confidential. Moreover, the different wave surfaces, different gears and chains on the platform must be tested repeatedly. This can only be corrected continuously at home to obtain specific and accurate data.

"Then what do you mean by this Taoist lord, what do you mean by this..."

"formula."

"You write this formula and let me take it back."

"This is not possible. The blackboard and chalk are related to poor children's studies. I can hand it over to the government. This is my job, and I must not hand it over to the government. Judge Liu, you have also seen that my family is poor. In order to create it, I borrowed more than 100 yuan in debt. The second king ordered me to compensate the other person for 120 yuan. I hand it over to the government. Am I a beggar?"

"This is also related to people's livelihood."

"It is not good to do with people's livelihood. Mencius said that if you are poor, you will be good at it. If you are prosperous, you will be helpful to the world. The two kings said to their subjects that a gentleman loves money and takes it with righteousness. A gentleman speaks ambition and takes it with virtue. A gentleman studies and takes it with diligence. A dishonest child is very disliked by me. I want to be an honest boy. When I am well developed, I will think about other people. Before I get rich, I can't take care of the world and can only take care of myself. Besides, this is my wisdom to make money, not an ill-gotten fortune. Judge Liu, I forgive me for not obeying my destiny."

Mencius said that if you are poor, you will be able to be good for yourself, and if you are prosperous, you will be able to be good for the world. But does Song Jiu mean this?

Liu Yi went back laughingly.

The next day, someone came to Kaifeng Prefecture again. It was not an official, but two yamen runners. They broke into the Song family and said, "The prefect asked us to pass on a message to you. I will compensate you for the money from the Zhugu family. But you are very hateful. I ask you, are you asking for money or death!"

"Two brothers, you told the two kings that the subjects need money and life." Song Jiumei smiled. This is great. One saving can save 120 guan. A penny will stump the heroes and heroes. He forced Qin Er Ge to sell the yellow horse, and it was 120 guan, which was worth 700 jin in cash!

A yamen runner continued, "The prefect asked us to tell you again, saying that you, a brave boy who is willing to do whatever you want, will definitely receive this hundred and twenty coins. This is okay, but you can only succeed, and you cannot fail and punish both crimes."

"Two brothers, why are you wronged? It's not that I received 120 guan, but that I paid for it."

"What's the difference? The prefect spoke again, let us tell you that you are a disciple. When you see the royal family, you can call yourself a minister, a humble minister, or other officials, you can call yourself Song Sheng. If you continue to be rude, you can call yourself a villain, what subject, a strange saying."

It seems that the praises of Song Jiu are really worth sending someone to correct it? In fact, it is ridiculing Song Jiu for being greedy for money and you are just a villain.

"Yes, yes." Song Jiu smiled bitterly, "It's a villain, how dare you be with this horned bull from Emperor Taizong of Song?"

"Brother, write down that formula."

After all, it's still for formulas.

Emperor Taizong lacked martial arts skills and attached great importance to internal governance. Before leaving that day, he deliberately looked at the high platform, which was also a side reaction.

Song Jiu’s ideas are not very comprehensive, and there is another reason why he attaches importance to them...

He immediately wrote down the formula, two simple and complex sets of formulas. The formula behind it is a more precise pulley set calculation formula. It is useless for the current Song Dynasty. Song Jiu honestly marked it, which letters represent what, but is there anyone in the Song Dynasty able to understand it now, especially whether the formula behind it will be more confusing? Song Jiu doesn't care.

As orthodox literati, they would regard what Song Jiu is doing now as a small way, with strange skills and tricks. Zhao Pu half of the Analects of Confucius ruled the world. So after reading the full Analects of Confucius, plus the Book of Rites, Spring and Autumn, Poetry, Book, and Yi, wouldn’t it lead to the Song Dynasty to achieve four modernizations?

However, various reasons have caused Song Jiu's device to attract many attention.

...

Four days later, it was sunny, and it was the end of March, and the peach blossoms had already faded and the weather gradually became hotter.

Song Jiu first found his brother-in-law and asked him to call on a few relatives and friends to carry the strange big wood to the Bian Dike. There were two strong men carrying a large bag of iron chains, while Song Jiu himself carried many ropes and went to the Bian River one after another.

Before assembly has begun, many people have come.

Song Jiu's father was quite famous in Hezhong during his lifetime. Boss Hu was the leader of the coolie. The two made a bet, which made the public talk about this topic these days.

The most important thing is livelihood. Many people in the river make a living by selling hard work and support their families, so they subconsciously pay great attention to Song Jiu's equipment.

Song Jiu first untied the iron chain bag, which was a very long iron chain, and there were also three strange things wrapped in iron sheets.

It is not difficult to understand in later generations, and it is not difficult to understand even in some Western countries. It is just a pulley set. The difference is that it may be the most precise pulley set in the world. The ship full of tourists pulled by Archimedes with a duplex pulley is to pull and move the ship, mostly on the river surface. This is something that a few boatmen can do, so the duplex pulley still has some defects, so people neglect its practical value.

There should be equipment similar to pulleys in this world, but none of them are very perfect.

Even if there is, Song Jiu and other people from the Song Dynasty cannot go to the West to verify.

This iron chain and three huge pulleys are the first difficulty. There is a big difference between how the iron chains are entangled and how to entangle them.

Then, two pulleys were hung on the wooden hook. These two pulleys were moving pulleys, and one pulley was to be hung on the top of the iron column to be used as a fixed pulley. Wood was a rotating shaft. The best way was to replace it with a bearing base, which would have less friction, but it was impossible to achieve it at this time. Song Jiu himself had little ambitions, and he did not expect that he could lift more than a dozen tons of goods, but only two or three tons of goods.

Song Jiu was loading a pulley, and Boss Hu walked over with a few subordinates.

This bet is beneficial to them. Needless to say, it doesn’t matter if you win, but it doesn’t matter if you lose. It helps everyone. At worst, you can go to the Zhu family to sing. The Zhu family has money, but they don’t want to benefit from it. So what if you have money, who is afraid of whom?

The people were crowded with great power, and they were all from the villagers. The big guys worked together to lift the wood onto the platform. The hole in the middle of the wood was placed on the iron pillar and fell smoothly on the iron wave plane. Song Jiu pulled out the iron chain facing the river and tied a net bag woven with thick hemp rope. This was the beginning. If you want to use it formally, you don’t have to use a net bag, or even some more bulky goods, such as thick wood weighing several tons, which can be assisted by two pulley sets and hanged directly onto the ashore.

In short, once this thing occurs, the entire unloading will undergo earth-shaking changes.

After assembly, Song Jiu said to Qi's brother-in-law: "You go down and pick up a ship of cargo."

"Okay," the honest and honest brother-in-law of the seventh brother-in-law came down to the dike to get the work.

This strange thing in ancient times appeared, which caused many people to watch on the Bian River. The people on the shore knew what it was used for, but the boatmen and merchants on the river did not know it, and they were all talking about it.

The seventh brother-in-law went down to take on the job.

There were many people who helped me just now, so I could tell where I could tell. I only noticed that Song Jiu, who was responsible for command and installation, did not pay attention to Qi's brother-in-law at all. It was okay to watch the fun, but the cargo could not be delayed. Qi's brother-in-law quickly received a ship of cargo. At that time, the big river boat with a 20,000 stone on the Bian River had not appeared, but there were big river boats with a nearly 10,000 stone. Not too many. First, the ship technical constraints, and the bridge constraints. Now it is mostly flat bridges, and the bridge holes are arched, but the bridge deck is flat, and the heavy ships are better. Even if the empty ship lowers the mast, it is impossible to pass when the water is large. So the capable heavy ships enter and the heavy ships return. Those who are not able will bring stone mud bags to press the ship, and then move the stone mud bags away again after returning. The larger the ship, the more difficult it is to sail. Until the Hongqiao appears, that is, a single-hole arch bridge, the bridge holes are large arc shapes, and the bridge deck is also small arc shapes, which increases the height of the bridge holes, so there are more and more large ships.

There is also such a scene in "Along the River During the Qingming Festival". Zhang Zerui's painting may not be the scene of Dongshuimen on the Qingming Festival. The first one is watermelon. Watermelon was introduced in the late Northern Song Dynasty, but it is impossible to eat watermelon on the Qingming Festival. The second one is river water. The Bian River in the Beijing section is close to the Yellow River during the flood season, mostly in summer and autumn. If it is in Qingming Festival, the river water is not that high and a deep embankment will be exposed.

During the flood season, the river water was high, and a boat passed by the Hongqiao outside the East Shuimen. Although the mast was lowered, the height was almost level below the bridge. Therefore, many people on the bridge shouted to the people on the boat, be careful, facing the middle of the bridge, otherwise the mast would hit the bridge.

That's a painting, but the ship should actually be bigger.

But most ships are small cargo ships worth hundreds of tons and dozens of tons.

The cargo that my brother-in-law received was porcelain. The porcelain was fragile and it was particularly troublesome to carry. Of course, the transportation fee was also more expensive than other goods.

After the price was negotiated, the seventh brother-in-law shouted at Song Jiu: "Xiao Jiu, can you take it?"

"Yes." Song Jiu put down the net bag, and his brother-in-law and Qi Balang put bundles of porcelain into the net bag.

The boatman was anxious and stopped him and said, "What are you doing?"

"If it is broken, it will compensate you." Qi Balang took his hand and pushed the boatman aside. Anyway, he brought your goods ashore. As long as it is not broken, no matter whether I use my hands to fight my shoulders or equipment. The shore here is the shore of the coolie, and the water here is the shore of the coolie, so the protest is ineffective.

Song Jiu and He Erlang began to pull the iron chains on the shore.
