"Judge Liu, if it is a suitable instrument and sufficient conditions, one person can also pull up 10,000 stone objects, but this kind of bulky equipment is not good, and 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 only be 200 stones, 100 tens of stones, and the effective weight that can pull 100 stones will be increased to 50 stones, 60 stones. ”

In fact, Song Jiu said it in vain.

"Xiao Jiulang-kun, where did you learn this knowledge?"

"It's simple, there are some records in the "Book of Ink", and the people are also using them, such as the deep wells in the arid areas of the north, the people use rollers to draw water, or the winch used to lift anchors on ships, the two principles are the same. Buddhists say that looking at a mountain is a mountain, looking at a mountain is not a mountain, and looking at a mountain is still a mountain. When I see the winch anchoring, I don't think about it, the first layer of the mountain is a mountain, and I think about it, there is some truth in it, it is not as simple as it seems, that is the second layer of the realm, and the mountain is not a mountain. If you figure out the principle, that is, the mountain is the mountain, the highest level of realm. ”

Or is it the same as saying it in vain.

"When will it come in handy?"

Liu Ling is not sure, maybe Song Jiu is fooling, maybe it is true, it is a mule or a horse, he must come out and slip away to know the truth of the Dao.

"At least four or five days left, it has to be corrected by repeated tests."

You can't test it on the high platform on the river embankment, the technique has to be kept secret, and the different wave surfaces on the high platform, the gears are different, and the chains are different, what impact will there be, you have to test it repeatedly, this can only be corrected at home to get specific and accurate data.

"Then what will you do with this Gong, what ...... Gong?"

"Formula."

"Write this formula out and let the official take it back."

"This is not good, the blackboard and chalk are related to the study of poor children, I can give it to the government, this is my job, and it must not be handed over to the government. Judge Liu, you have also seen that my family is very poor, in order to make it, I borrowed a debt of more than 100 yuan, and the second king sentenced me to compensate the family with 120 yuan, I handed it over to the government, and I became a beggar? ”

"It's also about people's livelihood."

"It is not good to be related to the people's livelihood, Mencius said, the poor are good alone, and the good is to help the world, the two kings said to the subjects that the gentleman loves money, and takes it in the right way, and the gentleman is ambitious, and the gentleman is virtuous, and the gentleman is diligent in learning. Dishonest children, the officer doesn't like it very much. I want to be an honest teenager, I will think about other people when I am developed, and before I get rich, I can't take care of the world, I can only take care of myself. Moreover, this is my wisdom for wealth, and not for ill-gotten gain. Judge Liu, forgive me for not obeying my fate. ”

Mencius said that if you are poor, you will be good to yourself, and if you are good, you will be good to the world, but does Song Jiu mean this?

Liu Ling went back with a smile.

The next day, someone from Kaifeng Mansion came again, not officials, but two officials, who broke into Song's house and said: "Fu Yin asked us to pass on the word to you, and the money of the Zhugu family will be compensated by the official for you." But you kid is very hateful, and the official asks you, do you want money or death! ”

"Back to the two poor brothers, you said to the two kings, the subjects also want money, and they also want their lives." Song Jiumei smiled, this is good, one province will save one hundred and twenty yuan, and one penny will stump the heroes, forcing Second Brother Qin to sell the yellow horse, and it is one hundred and twenty yuan, which is converted into cash, which is seven or eight hundred catties!

A servant then said: "Fu Yin asked us to tell you that you, a bold boy who can do whatever he wants, will definitely accept this one hundred and twenty yuan, which is fine, but you can only succeed, and you can't fail and fail to be punished for two crimes." ”

"Two poor brothers, wronged, it's not that I accepted one hundred and twenty yuan, but I paid it to others."

"What's the difference, Fu Yin spoke again, let us tell you, you are a son, you can call yourself a minister when you see the royal family, you can call yourself a minister, a micro minister, and you can call yourself Song Sheng when you see other officials, if you continue to be rude, call yourself a villain, what a subject, strange name."

It seems to correct Song Jiu's praise, is it really worth deliberately sending someone to correct it? is actually ridiculing Song Jiu for being greedy for money, you are a villain.

"Yes, yes." Song Jiu smiled bitterly, the villain is the villain, where do you dare to have a horn with this Song Taizong.

"Little brother, write down that formula."

Speaking of which, it's still for the formula.

This Emperor Taizong's martial arts are insufficient, and he still attaches great importance to internal governance. When I was leaving that day, I deliberately glanced at the high platform a few times, which was also a side reaction.

Song Jiu's thoughts are not very comprehensive, and there is another reason why he attaches importance to it......

He immediately wrote down the formula, the simple and complex two sets of formulas, the latter formula is a more precise pulley group calculation formula, for the current Song Dynasty, it is not useful at all, Song Jiu is very honest marked, what letter represents what, but no one in the Song Dynasty can understand it now, especially the latter formula will be more confusing, Song Jiu doesn't care.

As orthodox literati, they will regard what Song Jiu is doing now as a small way, strange skills and tricks, and Zhao Pu's half-book Analects rules the world, so after reading the entire Analects, plus the Book of Rites, Spring and Autumn, poems, books, and Yi, wouldn't it make the Song Dynasty realize the four modernizations?

However, for various reasons, Song Jiu's device has attracted a lot of attention.

……

Four days later, it was sunny, and at the end of March, the peach blossoms had long been gone, and the weather was gradually getting hotter.

Song Jiu first found the seventh brother-in-law, and asked him to call a few more relatives and friends to carry the strange big log towards the Biandi. There were also two strong men carrying a large bag of iron chains, and Song Jiu himself carried many ropes on his back and came to the Bianhe River one after another.

Before the assembly began, many people had already arrived.

Song Jiu's father was quite famous in the river during his lifetime, and Boss Hu was the head of the coolie, and the two made a gambling contract, which made everyone talk about this topic for the past few days.

The most important thing is livelihood, many people in the river are selling coolies to make a living and support their families, so subconsciously they also pay great attention to Song Jiu's instrument.

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

It is not difficult to understand in later generations, and even in some Western countries, it is a pulley group, the difference is that it may be the most sophisticated pulley set currently in this world, Archimedes used a compound pulley to pull the boat full of tourists, is pulling, making the boat move, mostly on the river, this is something that a few slender men can do, so the compound pulley still has some defects, so people ignore its practical value.

There should be pulley-like equipment in this world, but it is not very perfect.

Even if there is, it is impossible for Song Jiu and other people in the Song Dynasty to go to the West for verification.

This iron chain and the three huge pulleys are the first difficulty, how the iron chain is wound, how to wind, the difference is very large.

Then hang two pulleys on the wooden hook, these two pulleys are movable pulleys, and one pulley should be hung on the top of the iron pillar as a fixed pulley. Wood is the shaft, and the best way to replace it is to replace it with a bearing base, which will have less friction, but this is not possible. Song Jiu himself has little ambition, and he doesn't expect to be able to lift more than ten tons of goods once he hangs it, but only two or three tons of goods.

Song Jiu was loading the pulley, and Boss Hu came over with a few of his subordinates.

This bet is beneficial to them, needless to say if they win, it doesn't matter if they lose, it will help everyone, it's a big deal to go to Zhu's house and sing a song. The Zhu family is rich, but they don't want to get rid of it, no matter how rich they are, who is afraid of whom.

The big guys worked together to lift the wood up the high platform, and the hole in the middle of the wood rested on the iron pillar and landed smoothly on the iron wave plane. Song Jiu pulled out the iron chain facing the river and tied it to a net woven of thick hemp rope. This is the beginning, and if you want to use it officially, you don't necessarily have to use a net, and even some of the bulkier cargo, such as coarse timber weighing several tons, can be lifted directly ashore with the assistance of two pulley sets.

In short, once this thing appears, the entire removal and unloading will change dramatically.

After assembling it, Song Jiu said to the seventh brother-in-law, "You go down to pick up a shipload of goods." ”

"Okay," the honest and honest seventh brother-in-law went down to the embankment to pick up the work.

The appearance of this strange thing in ancient times caused many people on the bank of Bianshui to watch, and the people on the shore knew what it was used for, but the boatmen and merchants on the river did not know what it was used for, and they were all talking about it.

The seventh brother-in-law went down to pick up the work.

There were a lot of people who helped just now, and they could tell the difference, and they only noticed Song Jiu, who was in charge of command and installation, and didn't pay attention to the seventh brother-in-law at all. It is okay to see the excitement, and the goods can not be delayed and unloaded. The seventh brother-in-law soon received a shipload of goods, and at this time, the 20,000 stone river boat on the Bianhe River had not yet appeared, but there was a large river boat of nearly 10,000 stones. Not too much, one is the ship's technical constraints, the other is the bridge constraints, now it is mostly a plane bridge, the bridge hole is arched, but the bridge deck is flat, the heavy ship is a little better, the empty ship is to lower the mast, when the water is large, it is not allowed to pass, so the capable heavy ship enters, the heavy ship returns, and the inability to move the stone mud bag to press the ship, and the stone mud bag is removed again after returning. The larger the ship, the more difficult it is to navigate. Until the appearance of the Hongqiao, that is, the single-hole arch bridge, the bridge hole is a large arc, and the bridge deck is also a small arc, which increases the height of the bridge tunnel, so there are more and more large ships.

There is also such a scene in "Qingming Riverside Picture". Zhang Zerui's painting may not be the scene of the East Water Gate during 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 is the river water, the flood season of the Bianhe River in the capital section is close to the Yellow River, mostly in summer and autumn, if it is in Qingming, the river water is not so high, and the deep embankment will be exposed.

During the flood season, the river water is high, and a boat passes through the Hongqiao outside the East Water Gate, although the mast is lowered, the height is almost equal to the bottom of the bridge, so many people on the bridge shouted to the people on the boat, be careful, face the middle of the bridge, otherwise the mast of the ship will hit the bridge.

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

But most of the ships are small cargo ships of hundreds of tons, tens of tons.

The shipment that the seventh brother-in-law received was porcelain, which was fragile and extremely troublesome to handle, and of course the handling fee was more expensive than other goods.

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

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

The boatman was anxious and stopped: "What are you doing here?" ”

"I'll pay you for the break." Qi Balang grabbed his hand and pushed the boatman aside, anyway, get your goods ashore, as long as it is not damaged, it doesn't matter if I use my hand to shoulder or use equipment. The shore here is the shore of coolies, the water here is the water of coolies, and the protest is invalid.

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

Success or failure, in one fell swoop!
