"The length of the beam affects sensitivity, which only occurs when the quality of the items in the tray is poor." Cheng Jinzhou drew on the paper: "My design can avoid this situation by increasing the center of gravity and the choice of knife edge."

In the 21st century, he talked about very ordinary physics common sense. Occasionally pretending to be a teaching assistant to teach for the tutor, these are all thoughts. From the perspective of modern physics, they are just old-fashioned people. However, Liu Bin and Wu Zong listened very seriously, and the former was still silently calculating Cheng Jinzhou's formula in his heart.

"Let's replace the metal beam first." Cheng Jinzhou selected an iron bar from the table and handed it to Wu Zong and said: "Can you get out of your eyes?"

Wu Zong touched his beard and looked at the iron bars long with some worry. He did not have the appropriate star array to complete the work.

"Let Lu Xu come." Liu Kuang grabbed him and said, "This seems to be a step further than the result you submitted to the association last time."

Lu Xu hummed twice in dissatisfaction, but still stretched out a finger and found the right position to drill on the iron bar. He saw that the place where his fingers were in contact with him turned slightly red, and the iron bar was inserted deeply by his fingers like plasticine.

"Thermal star array." Lu Xu bulged his biceps.

"Then get all these dozens of pieces out." When there was a good laborer, Cheng Jinzhou didn't want to let go at all.

Liu Kuang touched his beard and looked at the formula listed by Cheng Jinzhou. The leader stopped working, and Wang Linghe and Xiang Xin also surrounded him. Wu Zong and his two apprentices were so excited that they seemed to be a monkey who had been on medicine. They wanted to jump but couldn't jump up. They squinted their eyes and wanted to sleep, but were hazy and full of fantasies. For them, demonstrating work in front of a fourth-level star warlock was like a young company commander meeting the commander, which felt a little like awarding a medal.

"If you have time in the future, it is better to change it to a hollow one." Cheng Jinzhou commented. The iron bars as experimental materials are finely crafted, and there are no root burrs on the surface, let alone rust spots, etc. With the current production efficiency, you can imagine that the price must be very strong.

"The mass of hollow is difficult to control." Putting down the research work, Xiang Xin transformed into a curious baby again.

Cheng Jinzhou smiled and said, "It's not that difficult, the better balances should be hollow."

Judging from the current balance design of the Daxia Dynasty, the sensitivity of the balance is related to the length and weight of the beam. Gentlemen with good skills will definitely think of making hollow metal beams.

Cheng Jinzhou said, and began to organize parts in his hand. Every time he wanted to modify it, he could say a few words casually. Lu Xu also became an artificial machine tool to help him modify it in real time. Controlling the size of the weight and determining the accuracy of the swipe code are all minutes, and its convenience is enviable.

Wu Zong turned into a purely attack. Of course, he was the happiest job among the few people. He had to be angry when he left at this moment.

With the help of a genuine star warrior, Cheng Jinzhou combined the balance is also very fast. He also used standard weights to calculate the accuracy, and the data is accurate to two decimal places.

Even Liu Kuang nodded and said, "If you use it like this, you will know how many errors there are."

Since the 20th century, people have been dealing with errors like this. Cheng Jinzhou curled his lips and took out the best performance of the balance and said, "Wang Linghe Xingshi, thank you for your materials. I'll give this balance to you."

The balance with an accuracy of 0.07 (Note 1) is hard to buy in the Star Warlock store. Wang Linghe did not refuse and reached out to take it and smiled: "It is still very inspiring to see your research on torque."

"Where?" Cheng Jinzhou laughed, and he couldn't remember many specific places when talking about physics. However, although the last time he got "Mechanics and Metrics" from the library only has one volume, it can provide good supplements in details. It is naturally a piece of cake to copy the content and write a paper from hundreds of years ago.

"I'll take the rest back and make it." Seeing that it was getting late and the humanoid machine tool had roughly cut the parts, Cheng Jinzhou stood up and said goodbye with a smile. At least fifteen or sixteen scale materials were more than enough to make them back.

Xiang Xin hurriedly stood up and said, "I will sort out the research results for you."

"Uh... how can you be so embarrassed?" The association's contribution points are very valuable after all. He is not familiar with the paper model. It would be better if someone helps. The corresponding torque content is not valued by Cheng Jinzhou, after all, it is just a small branch of an era.

Seeing that Cheng Jinzhou was not rejecting, Xiang Xin sat down with a smile. It took not much time to collect and organize the research results, but he would have a deeper understanding of the content. If necessary, he could ask the original owner and learn more.

Liu Kuang didn't mind taking on "private work" on his land. He also smiled and sent Cheng Jinzhou and others out, and specifically instructed: "I remember we will set out early the morning after tomorrow."

Cheng Jinzhou thanked again.

When he came out, he refused to let Wu Zong go and pulled him and said, "There are still some things I want to discuss with you."

The discussion is fake, and the tyrant is real. Wu Zong doesn't mind. Staying up late is common for a star warlock. If you can learn something, what's the point of being tired?

...

It was midnight when he got home, and the candlelight was still lit in the study. Cheng Jinzhou felt a little guilty and went to settle Wu Zong first, but walked over gently.

"Dad." He gently pushed open the door and it was Cheng Yunan reading a book under the lamp.

"Your mother is going to bed first." Cheng's father clamped the bookmark into the pages and placed it on the table and asked, "Have you said goodbye to Mr. Liu Kuang?"

"They will also set off to Beijing the day after tomorrow and invite me to take a flying boat together."

Cheng Yunan was stunned for a moment, then said with plastic surgery: "I won't bother me."

"No." Cheng Jinzhou shook his head firmly. He was absolutely determined to choose between the plane and the carriage.

"I feel much more at ease when I'm with the four astrology masters. After arriving in the capital, don't have trouble and focus on being low-key." Cheng's father paused and said in a serious tone: "Your approach to Hongrizhuang is not advisable. Yunquan has been dealing with your affairs for a while."

Cheng Jinzhou was silent. He killed the garrison captain in Hongrizhuang and placed it in other prefectures and counties. The army had long rushed forward. But as a member of the Cheng family, Cheng Yunquan, the chief secretary, certainly did not allow such things to happen, and the work of suppressing was not easy.

Father Cheng sighed and said, "Go to rest early, don't think too much, I'll go to bed too."

"Yes." Cheng Jinzhou bowed slightly and left the house with a slightly heavy expression. Before killing, he was very angry; when killing, he was very decisive; after killing, he couldn't help but feel a little depressed. For a young man who grew up in a peaceful environment and was mentally normal, it was not so easy to kill others with his own hands.

Shimo was carrying a lantern and waiting under the steps, and said in a low voice: "Mr. Wu Zong is waiting for you in the wing room."

"Go over." Cheng Jinzhou grinned, realistic plans will always come first.

...
