Sun Xian ran over in two steps, bent down, and turned his face sideways with a smile on his face, wanting to listen to Han Du's lesson.

Han Du raised his right hand high and slapped Sun Xian squarely. "Pulley, I'll let you pulley. Your whole family is a pulley. Let's see if I don't turn you into a pulley."

Sun Xian, an honest man, did not dare to hide when faced with Han Du's slaps one after another. He just endured it honestly, with bitterness all over his face.

Xue Xiang was still quick-sighted and quickly stepped forward to pull Han Du away. "What are you doing? If I break him, you won't feel bad, I will."

Han Du panted for two breaths, looking like he was still unfinished.

Sun Xian quickly bowed down and said, "The student is so stupid that I made you angry. If you haven't vented your anger yet, please teach the student a lesson. I just ask you not to give up and help the student clear up his doubts."

Han Du snorted angrily, stepped forward and looked at Sun Xian who lowered his head, and shouted: "Get up."

"Thank you sir."

Han Du took two steps forward, looked at the continuously rotating eccentric wheel, and said without looking back: "If there is Tao but no technique, the technique can still be sought; if there is technique but no Dao, it is only the technique. What I teach you is the Tao.

It's force

The fundamental principle of learning. And the pulley is just an application under this principle, it is a technique. When you encounter a problem, you don’t want to rely on Tao to solve it, but you want to come here with a pulley. Do you think I should be angry?

"

"The student has been taught, please give me some advice." Sun Xian finally understood where he had gone wrong, his face turned red, and he quickly bowed his head and begged humbly.

There is no need for a heavy hammer to play the drum. Sun Xian is indeed very talented in the field of mechanics.

He waved his hand and said, "Turn off the fire."

Several academy students skillfully pushed out the burning coal. It was obvious that this was not the first time they had done such a thing.

The scene where Han Du beat their husband just now frightened them. But soon they all became excited again. After all, the opportunity to see their husband being beaten by their master was rare.

However, no matter how excited they were, few of them were stupid enough to show it on their faces. Their master was always so rude with his hands, and they were not sure whether Mr., who was usually gentle and gentle, would behave the same way. If Mr.

If you see the clues and find an opportunity to beat them up in the future, wouldn't that be asking for trouble?

It just so happened that the master ordered to evacuate the fire, and they could take this opportunity to hide the expressions on their faces.

As the coal was removed, the temperature of the water in the iron barrel quickly dropped, and the vertical rod that had been moving up and down returned to its static state.

Han Du stepped forward and took a look at the eccentric wheel and said: "This thing is not good. It cannot be made of wood."

Sun Xianxiao laughed twice and explained: "At first, the students thought that the power was too small, so in order to save energy, they made this thing out of wood."

This time, Han Du did not get angry, but patiently explained to Sun Xian: "I noticed when the eccentric wheel was turning just now. Every time it pauses at the farthest and nearest places."

Sun Xian nodded. He naturally knew about this phenomenon. After all, they didn't know how many times they had seen it. Sun Xian was extremely impressed by Han Du's ability to discover this problem after only seeing it once.

"The student knew about it, but when he saw that it had little impact, he didn't take care of it."

Han Du smiled and said meaningfully: "Not much impact? That's because your current steam engine is still very crude and cannot be used in practice. If this problem is not solved, when you actually use it, you will

I found that this thing often gets stuck here and even rotates in the opposite direction."

Sun Xian also knew the seriousness of reverse rotation. If it became like this, it would be completely useless. He quickly asked: "What should we do?"

Han Du touched the eccentric wheel with his hand, broke it hard, and said: "It's very simple, replace this thing with iron."

"Sir, if it were made of iron, it would probably weigh a hundred pounds. Isn't that too heavy?" Sun Xian asked worriedly.

Han Du sneered and said: "Too heavy? I think it's a bit light. I'm afraid a hundred pounds is not enough, but a hundred and fifty pounds is about the same."

Sun Xian was stunned and asked without thinking: "If it is so heavy, can the machine carry it?"

Han Du raised his eyes to look at Sun Xian and said with a smile: "You will know if you can move it with me if you try it?"

Sun Xian was immediately speechless by Han Du's words. Yes, you will know after trying it.

In this case, Sun Xian turned around and found someone to build a larger cast iron eccentric wheel.

Han Du raised his hand to stop him and continued: "It's not over yet, why are you anxious."

"Sir, do you have any other instructions?" Sun Xian bowed his hands and said.

Han Du continued: "The eccentric wheel needs to be modified, and you also need to make a few other wheels. In this way, I will draw some pictures for you, and you can find someone to build them according to the drawings."

"Okay, sir." Sun Xian nodded and agreed with a smile.

It’s not often that I can see my husband drawing pictures in person. Now that I have the opportunity, why not take a closer look?
