Chapter 295: Uncle Guo

The master craftsman wanted to raise his hand, but after thinking about it, he secretly retracted it, and when the little girl was angry, her aura was strong.

Then I saw Su Xiaomei slapping two booklets on the table: "Even if you understand the first volume, there is still a second volume and a third volume!" Asymptote gears on hydraulic devices, who understands the principle? Who can draw?! ”

It's dangerous! The master craftsman patted his chest, but fortunately Lao Tzu didn't raise his hand just now!

After Su Xiaomei finished speaking, she turned around and drew a ruler on the blackboard, and after a while, she drew a big gear, a calculation formula that slipped next to it, and then patted her little hand stained with white ash: "It's so troublesome, who will draw one?" ”

The heads of the craftsmen were swaying, and this time they were completely honest.

Su Xiaomei gritted her teeth and said, "Whoever makes trouble again, the squad leader will blast me out!" Anyway, in the end, it's not like I lost the opportunity for promotion and salary increase! ”

The master craftsman stabbed Zhang Qi who was at the same table with his elbow, and said in a low voice: "Mr. Xiaoqi, can you draw?" ”

Zhang Qi buried his head and was wrestling with the elliptical question that Su You gave him: "Listen carefully, don't open any pot and mention which pot!" ”

……

The case entered a strange atmosphere.

For the first time, the craftsmen felt that the things they had studied for generations could extract a metaphysical subtlety from them.

All laws are accurate, and this is an inverted conical system.

A straight line, a circle, a few simple truths, and then a spiral of reciprocating superposition and expansion, and finally form a logical and uneasy system.

I used to work according to the ancestral method, but I didn't know why it was.

It was only now that Mr. Xiao explained the truth contained in it, and the craftsmen understood - oh, it turns out that the ancestors designed this place this way because of this theorem; The place was designed like that because of the formula......

Although I am still very ignorant, everyone understands that this is definitely a profound knowledge that cannot be run.

The first thing countless craftsmen did when they returned home was to recruit the babies: "Come on, come on, Mr.'s class is here today, let me tell you, you have to understand the things of the ancestors, if you don't understand, you won't have Granny Chen's meatloaf to eat tonight......"

In fact, the great craftsmen of the past generations may not be able to understand the theoretical principles, but they have rich practical experience and unconsciously apply these principles to production.

However, this did not prevent Su You from deliberately misleading, watching Mr. Xiao praise the magical design of various ancient French styles in the case, and then pulling the craftsmen to analyze the scientific knowledge contained in it, the craftsmen felt that they were ashamed of their ancestors.

The things handed down by their ancestors will not be able to do anything, which is rebellious for the Song people, and they can't raise their heads to see people when they go out of the door.

In the Song Dynasty, temple supervisors, various trick officials, such as Si Tian and medicine, many of them are family inheritances.

The same is true for the Gang Workshop.

Many craftsmen begged to come over, Mr. Xiao, hehehe, a few people in the family who are not angry, can you also come and listen?

Just when we go home, there is always a layer apart, and these are all related to the money and food of the babies in the future.......

Su You's hand waved, love to come, now that the circular saw and the like are in place, if you can't sit down, you will go to the brother unit to borrow someone from the prison and repair the classroom!

Today Gao Shilin also came, and brought a middle-aged man who was older than him, and a teenage child.

said that people are children, but in fact, they are about the same age as Su You.

Su You talked about the principle of the micrometer and the micrometer today, and after class, he came over with his schoolbag: "Su You has seen the verdict of the case. ”

Gao Shilin asked, "How?" Can the craftsmen still learn? ”

Su You said with a smile: "The progress is very fast, most of the things they would have been, just to refine it." ”

Gao Shilin said with a smile: "I will introduce you, this is my maternal uncle, Cao Tong." Ah yes, it's the brother of the imperial envoy who has seen the Great Xiangguo Temple. I'm curious about the case course.,Let's take a look.。 ”

Then this one should be called Uncle Guo.

Cao Tong arched his hand and said: "The micrometer and micrometer that Mingrun talked about make people suddenly open, and the thing that happened to ask for each other should be related to this." ”

Su You smiled: "Let's go to the teaching and research department to talk about it in detail." ”

When I came to the teaching and research room, Zhang Zao, Zhang Qi, and Su Xiaomei, one person and one desk, were correcting their homework.

The walls of the teaching and research room are covered with various teaching aids, and the bookshelves are full of various brass mechanical parts.

After serving tea to a few people, Su You asked, "I don't know what happened to the nobleman?" ”

Gao Shilin said: "My uncle, who has taken the path of a literati, is an expert in music, rhythm and poetry, and this time he is going to Yangzhou to be an official, so he wants to ask Mingrun one or two." ”

Cao Tong said: "Yangzhou is prosperous, but the floating habits are too heavy, and the competition is exaggerated by extravagance, which is a bit similar to Yizhou." I want to learn from the way of Meishan, so that it can know the etiquette with enough food and clothing. If you think about it, you can only start with books. ”

Su You said: "Is that going to print it yourself?" Or buy books from Meishan? ”

Cao Tong said: "Meishan books are excellent, but the price is really expensive, I think it is better to print it yourself." ”

Su You said: "This matter is not difficult, the Meishan historian makes excellent porcelain, and Uncle Guo can ask them to buy a set of porcelain codes, and then everything else will be easy to do." ”

Cao Tong smiled and said: "Originally, I wanted to make my own code, but I just listened to a class from you, and it is better to study for ten years." The movable type code is only Meishan is excellent, not inferior to the engraving, but there is a reason. ”

Su You smiled: "Indeed, and the lesson just now is only one of the reasons. There are all kinds of improvements, dozens and hundreds of improvements, word codes, ink, paper, processes, accumulation, only now Meishan printing. Uncle Guo went to Yangzhou to promote the text, and the requirements were not too high. ”

Cao Tong said with a smile: "Please ask Mingrun for such a porcelain code." ”

Su You said with a smile: "This matter is easy, I will repair a letter and let them ship it directly to Wuzhong, Brother Cao will arrive in Yangzhou and go to the Sitong Commercial Club to get it." ”

Cao Tong was overjoyed: "That's great!" ”

A few people were talking happily when they heard Su Xiaomei's voice sound: "Then who, don't mess with the mechanical teaching aids!" ”

A few people turned their heads and saw Cao Tong bringing the child, who was reaching out to fiddle with the brass artifacts on the shelf.

Gao Shilin said embarrassedly: "Uh, this ...... This is my family...... Little brother. ”

Su You took the workpiece off: "You think it's interesting, right?" Here's how it works, you turn this wheel and see. ”

When the boy turned the wheel, he saw two cogging in front of the connecting rod, and with each revolution, the cogging pushed forward.

Su You smiled: "This is called a stepping system. With each turn, a step occurs. ”

The child asked, "What's the use of this?" ”

Su You said: "Let's assume that a piece of leather armor needs to be equipped with rivets to assemble shoulder pads, heart guards, and lock straps. Through this machine, a conveyor belt can be made, and a worker is only responsible for the shoulder guards, which are loaded and placed on the conveyor belt, and the conveyor belt is transported to the next worker who only has the heart guards installed through the walking machine. ”

"In this way, each worker only needs to specialize in one detail, and a stepper can form an assembly line, which not only improves efficiency, but also makes the process more exquisite."

The kid nodded: "That makes sense, but it's too slow for the water to take such a small step when it turns around." ”

Su You took another component of the gear set: "You see, this is the mechanical part used to change the speed. The large wheel can make one turn, and the small wheel can make countless turns, and the ratio between them is determined by the ratio of the number of teeth of the two wheels. You can try to count, count, and turn around again to see if that's the case. ”

The kid went to the side to calculate by himself, and Su You came back to continue drinking tea and chatting with Cao Gao and the others.

Gao Shilin said: "Mingrun, my brother hasn't been playing around during this time, what kind of hell mine did you say, his legs are almost thin, and his boots are worn out several pairs!" ”

Su You added tea to the two: "Since you are so proud, do you think you have found it?" ”

Gao Shilin laughed: "Tanhualang really knows everything, this thing is found in Nanyang Horse Shoe Town!" Speaking of which, with the addition of this thing, if the steel smelted is not fierce, my brother will ask you to pay for your boots! ”

Cao Tong said: "Speaking of Horseshoe Town, there is an allusion. ”

Su You raised his glass and saluted: "Uncle Guo, please speak." ”

I heard the young man who was calculating the proportion of teeth say: "Emperor Guangwu of the Later Han Dynasty Liu Xiu raised an army to attack Wang Mang, and was chased by Wang Mang to that place. In order to get rid of the pursuers, Liu Xiu deliberately threw the horse pedal on the ground, and then went away from the fork in the road, and finally escaped from danger. ”

"After Liu Xiu became emperor, he named that town as Horse Shoe Town! I calculated the gear ratio of yours, the big wheel is 120 teeth, the small wheel is 12 teeth, the big wheel is one circle, the small wheel is ten times, hahaha is really simple. ”
