Rebirth King of Pit Climbing

() In the evening, Yang Ling received an unexpected gift. Sun Hunter actually came to see him in a green carriage and brought him a flower dew, wine and some braised beef and mutton. These things can

After a while, Yang Ling felt a little moved. It turned out that someone was still thinking about him. Perhaps this was the family, his own family. This picture suddenly appeared in Yang Ling's mind. Maybe one day, he squatted in the detention center.

Sun Hunter was wearing a coarse cloth coat, holding a food box in one hand and holding a fat boy in the other. Bah, Bah, what a mess.

"It's such a hot day, why don't you stay at home? It's hot and messy." Yang Ling blamed.

Sun Hunter smiled slightly: "Today, Old Prime Minister Shen sent someone to say that the young master is leaving home for a while. I'm not relieved, so I specially sent you some common products," Sun Hunter handed Yang Ling a bag and said, "There are some explanations inside."

If the young master feels uncomfortable, use some medicine for the summer.”

Yang Ling took it and said, "Thank you, by the way, is there something happening today?"

"Today, the young master seems to be looking for you, but I didn't see you. Let me tell you that he is the Eastern Palace Guard now and will take office tomorrow. Maybe there will be fewer opportunities to meet in the future." Sun Hunter said as he said

Another food box was taken from the car, which contained chicken soup and served a bowl of it and said, "I'm afraid that the young master wouldn't eat well, so I learned to make chicken soup. The first time I cooked it, I didn't know how it tasted, so I tasted it.

?”

Yang Ling took it with a touching drink and smacked his lips in Sun Hunter's expectant eyes.

"How is it?" Sun Hunter asked with concern.

"It's already very good with the skills of making chicken soup for the first time," Yang Ling smiled and said, "Remember to add salt next time, it may taste better."

Sun Hunter left, Yang Ling stood there a little lost. It is said that to conquer a man's heart, he must first conquer his stomach. In fact, this thing is the same after eating. The key is the heart inside, Yang Ling can

Feeling Sun Hunter's intentions, I feel that I will be conquered by Sun Hunter little by little.

Yang Ling no longer cares about gunpowder. Open a little window and blows a gust of wind. Science will always have a day when the melons are ripe. After visiting the marshalling prison in a complete manner, Yang Ling expressed strong dissatisfaction with the backward production process in the marshalling prison and decided to

To achieve a little automation.

There is a hill behind the craftsmanship supervision, and there is a waterfall with a good drop. Of course, Yang Ling would not ignore such natural power. Yang Ling spent a day designing a set of transmission devices. As mentioned earlier, Yang Ling did not travel through the previous university.

I studied automation, but there is a course called engineering drawing in my freshman year, so there is no problem in designing some gears that are not compatible.

The only problem is that after looking at Yang Ling’s three-view set, all the craftsmen were stunned. None of them could understand. Yang Ling had to personally supervise the gears and build the connecting rods under the high temperature. For subsequent maintenance,

Yangling did not design too complicated parts. While creating them, he explained the size issue and told them that many things must be made.

Lord Tian was very disdainful of Yang Ling's actions in the craftsmanship supervision, but with the joint writings of the Ministry of Works and the Ministry of War, Lord Tian had to bite the bullet and cooperate with Yang Ling's actions.

In the evening, Yangling organized craftsmen to study, which was purely voluntary. Unexpectedly, under Yangling's suggestion, the Gunpowder Group's mission went surprisingly smoothly. They were the first to respond to Yangling's call for learning, and then followed everyone

All are here. Yang Ling is very satisfied. With such a group of hardworking and willing to study, I believe that under their leadership, there may be a great figure in hundreds or eighty years, and it may be possible to lay the foundation for modern science.

Yang Ling smiled and said to everyone, "I said a word to the people who played Pili Fire at the beginning, called energy, so what is energy? In simple terms, energy is strength. I ask you, who can you do one of you.

Carrying a fifty kilogram stone with your hands?"

Everyone shook their heads and said they couldn't do it. Even Li Goudan, who had eight-pack abs, said they couldn't do it.

Yang Ling smiled slightly and said, "I can, and you can do it too!"

Everyone looked at Yang Ling in disbelief, but did not dare to jump out and question Yang Ling's statement.

"I know, you don't believe it," Yang Ling clapped his hands and said, "I'll take you to do an experiment. After completing this experiment, you will believe what I said."

The simple leverage principle makes everyone play curiously, and no one will believe that they can move a huge stone with just a little effort.

"Energy is a very interesting thing," Yang Ling said with a smile: "First of all, energy is conserved, maybe you don't understand conservation. If you do this, you must use a lot of strength to move a stone.

.But, you have tried it yourself just now. You can move such a big stone with just a little effort. From this point of view, the conservation of energy I just mentioned seems to be wrong, right?"

All the craftsmen smiled honestly.

"In fact, energy has always been conserved, but the experiment I took you to do just now also involved another very interesting thing, called torque. In this way, now you can see if you can move this stone." Yang Ling said and adjusted

A little fulcrum.

This time it was everyone's turn to be stunned again. It was still the same stone. Even if you didn't use leverage, you could pick it up with your bare hands. But now you can't move with all your strength. Everyone looked at Yang Ling curiously and waited.

Yang Ling explains the answer.

"I just talked to you about the torque issue. The real energy is not exactly equal to strength. I just moved this fulcrum, so moving this stone may not require fifty kilograms of strength, maybe three hundred kilograms

, it is four hundred kilograms, the mystery lies in the distance from this fulcrum to the stone. This distance can be called a torque. The distance from your hand to the fulcrum can also become a torque. The conservation of energy and force are related to the moment.

The shorter the force is, the greater the force is needed. If the torque is longer, the smaller the force is required. Maybe you don’t know what kind of relationship there is. To be honest, I don’t remember it very clearly, but you

Just remember what I said just now." Yang Ling said: "When we work, we need a lot of effort. We may work for a day and don't want to move when we are lying in bed, because you don't know how to use it.

I saw this strength. When they debugged the crossbow, they even used the strength to eat the nai in order to open the crossbow. Of course, we know that the more force the crossbow, the more powerful the crossbow, the power of the shed out.

The bigger it is, but how many people on the battlefield can pull a strong bow and crossbow? At this time, using the torque I just told you can achieve twice the result with half the effort. We can artificially create torques that are beneficial to us, so that we can want

The strength becomes smaller."

Yang Ling held up the gear that had just been built today and let the two gears get together, saying, "This thing is called a gear. Through it, your strength will be transmitted layer by layer, which is equivalent to increasing the torque."

Yang Ling said as he raised another pulley and said, "This thing is called a pulley, and its function is the function of the fulcrum just now."

...

The class was held until late at night, and all the craftsmen were full of admiration for Yang Ling. In fact, Yang Ling said things that they would use in their daily lives, but no one would think about the truth. Now Yang Ling has been told.

Suddenly I seemed to see something even more different.

Today, Yang Ling brought everyone to the waterfall. A few days ago, a water truck was already set up here. China has used water power since ancient times, but at most it will be used to pound rice. The complexity of labor has led to labor.

The people lack understanding of motivation. Yang Ling’s task today is to unveil this veil for them.

All gears and connecting rods were installed bit by bit under Yangling's guidance. Yangling carefully added lard to lubricate the gears and gears. When the connecting rod was used to put the water wheel on, it would rotate with the water wheel.

All the gears also began to bite and rotate, and the craftsmen cheered. Yang Ling smiled with satisfaction. He believed that one day the Chinese nation would see all kinds of things from it, which would greatly improve production efficiency.

Although the various machinery has not been in place, Yang Ling is not in a hurry, "Look, if you hang a large piece of iron here, you don't need someone to hit the iron, so that the iron smelting can be much faster. Look at this place again, if this is

Put a piece of sand and gravel on it, just put the weapon on it, it will be fine in a while. By the way, I will go back and teach you how to build leaves and then put them on. In the future, you don’t need to use a fan on hot days. You can do it.

The wind blows." Yangling pointed at each place, telling the speed and speed of the gears because of different linkages, and explaining the use of each place.

In the next rift of Yangling, suitable machinery was designed for various places. After the blacksmiths were rushing to work at night, the trial results were very satisfactory. Yangling even found a few of the most ingenious craftsmen.

They were asked to see the teapot and boil water for a day. Everyone was puzzled. They didn't know what it looked like to boil water for teapots. When asked Yang Ling, Yang Ling learned from the Buddha to pick up flowers and smiled: "You can't say it, you can't say it one day.

You will understand."

Half a month passed in a blink of an eye. Sometimes Yang Ling would lament alone that he was indeed a dilapidated life in heaven. It seemed that he felt very happy with these people. No matter what, he wanted to live up to an engineer.

, it has fulfilled a childhood dream.
