Chapter 490

Wang Yang used such books to kill time when he was idle, but he never imagined that he would find a lot of physics knowledge and physical technology that were still widely used in later generations.

And Wang Yang asked the entire people in the ordnance superintendent, and these guys didn't seem to have much interest in this kind of thing, thinking that these things had little to do with the work they were engaged in.

This made Wang Yang's heart very indignant, and at the same time, considering the military production of the Great Song Dynasty, he actually really needed this thing, and more importantly, the bows and crossbows of later generations used a large number of pulley sets.

So after Wang Yang had this idea, he asked people to build a pulley set first, but before he could start inventing and creating, he was leaving.

And the appearance of Zhao Ji made Wang Yang feel that this might be a good opportunity. So I decided to take it out to tempt Zhao Ji, and now I see the appearance of stars in both eyes of this product, and sure enough, this thing is really interested in these novelties.

"I can't imagine that the ancient sages have invented such a magical object, which is really admirable." After Zhao Ji looked at the description of pulleys and pulley sets, he couldn't help but feel a lot of emotion.

Wang Yang exhaled the turbidity in his chest and said slowly. "You think, my Da Song's bed crossbow, one pull, it takes nine oxen to pull, and if you have a suitable pulley set, even a cow can wind the bed crossbow......"

"That's right!" Zhao Ji's eyes had already changed from shining to green, and he subconsciously pulled the rope again. "By the way, sir, can you make this thing lighter?"

"Of course, because the amount of effort saved by the pulley block is determined by the number of rope strands, and its mechanical efficiency is determined by the gravity of the pulled object, the gravity of the movable pulley and the friction." Wang Yang nodded and replied.

"That is to say, when there are ten strands of rope, then, if you want to pull up the weight of three hundred catties, you only need to spend thirty catties of strength."

"However, the number of strands of rope is not as much as possible, after all, the more ropes, the longer the distance you need to pull......"

"Sir, I still don't understand what it is, why don't you tell me about it from the beginning?" Zhao Ji looked at Wang Yang and said with a blank eye. "I really want to know how it works."

"Since that's the case, then I'll give you a good talk, first of all, let's start with the most basic things...... Wang Yang didn't expect Zhao Ji to be so fond of learning, and in desperation, he could only harden his head and become a physics teacher.

Fortunately, his physics knowledge was not returned to the teacher, and although Zhao Ji is not a good emperor, he does have a good brain and can draw inferences.

Even the physical formulas that Wang Yang wrote down for him, he was quickly able to learn and apply them. This really made Wang Yang secretly smash his tongue, if this Zhao Ji was thrown into the future, he would definitely be a typical academic tyrant.

"I see, I understand, the original truth is so simple, as long as you pass this formula, you can easily get the results you need." After Zhao Ji understood those formulas, he was soon able to calculate the results independently.

Then, in order to prove that there was no problem with his results, he even took matters into his own hands, and under the guidance of Wang Yang, he personally changed the number of strands of the rope of the pulley group, and sure enough, the change in the number of strands of the rope was passed.

The size of the power used also changed, and the length of the rope pulled also changed, and Zhao Ji once again bowed deeply to Wang Yang with a look of adoration. "The ancients had clouds, and when they heard about it, they could die at night. The things that Mr. Today taught really made Lonely, as if a new door had been opened. ”

"It doesn't have to be so, this knowledge actually comes from the ancient sages, and I just made a little bit of a summary." Wang Yang pretended to be modest.

"But I'm afraid that only you, sir, will notice the combination of these things and reality, if it weren't for you, how could the knowledge of these ancients be able to see the light of day again." Zhao Ji continued to worship the authentic with a face full of admiration.

Looking at his shining adoring gaze, he almost knelt down and called his father, as an unmarried boy, of course Wang Yang would not allow him to do this, the important thing is that Wang Yang was very worried that in that case, the coffin board of Emperor Shenzong, who had just been dead for less than ten years, would probably not be able to hold it down.

And after Wang Yang appeased His Royal Highness Duan Wang, who was too excited, he began to tell him about his thoughts and concepts, and Zhao Ji listened very seriously, and even simply took out a pen and paper and recorded Wang Yang's words in detail on the paper.

Most of what Wang Yang said was about the relevant concepts and ideas of the combination of pulley sets and bows and crossbows, until the beginning of the lantern, and Zhao Ji took the notes he recorded by himself and handed them to Wang Yang for review, and Zhao Ji left the ordnance prison with this note with a reluctant face.

Only then did he leave the office, and he saw that outside the office, Gao Yu and Li Yu, who were already dressed in green official uniforms, were bragging and farting with Wu Qilang there.

"When did you come here?" Zhao Ji raised his head and glanced at the sky, only today, he felt that time passed too fast, he was immersed in the ocean of knowledge while swimming, and he really had a feeling of reluctance to go ashore.

"It's been almost half an hour since I came, but Lao Wu said that you were studying something very important inside, so we didn't go in to disturb you, and waited here." Li Yu smiled and explained.

"By the way, Brother Qingjun, why didn't he come?"

"That guy has been to Master Su's mansion since the afternoon, and he hasn't returned yet......" Li Yu said helplessly.

"He really wants to go to the border town." Wang Yang couldn't help but roll his eyes, yes, as the so-called world wants Yu Niang to marry, let him do it himself.

#####

A vote of people rushed to the restaurant to eat and drink, and Zhao Ji, the little prince of Dese, told the scene when the holy decree was issued to Wang Yang today.

"Sir, you don't know yet, this time you were promoted, almost no one from the Manchu Dynasty's civil and military ministers stood up against it, it seems that they just hope that you can leave Bianliang and leave the court."

"They can only do this for a while, at most, Sir is so young, and he has such outstanding merits, if he goes to the border town, he will make some contributions. When they return to the court at that time, I am afraid that they will definitely regret their actions today. "The scheming Gao Yu is in a very good mood, so he talks more.

Zhao Ji jumped up for the first time, raised his wine glass and shouted loudly. "Yes, I will wish Mr. Ma Gong success in advance, make contributions in the border town of Shaanxi, and strive to defeat the Xixia Xiaoxiao, even if I can't catch the lord of the Xixia Dynasty, I will capture his wife, the old woman who turned his back on my Da Song Dynasty, and sacrifice it to prisoners."

"Yes, yes, that's what you do, let's congratulate Brother Xian on your victory after you caught that Xiaoliang, and let that Xiaoliang bring tea and water to Your Majesty...... And the virtuous brother, you will definitely be able to worship the marquis. ”

Wang Yang reluctantly accepted the blessing of this gang of bad friends, after hundreds of thousands of people went to catch a small beam, do you really regard my Wang Daguan as omnipotent, and he can't be a superman wearing underwear?
