Future library

"The length of the beam affects the sensitivity, which will only occur when the quality difference of the items in the pallet is high." Cheng Jinzhou drew on the paper: "My design can avoid the problem by improving the center of gravity position and the selection of the knife edge. Open this situation.”

In the 21st century, what he talks about is very common physics knowledge. When he occasionally pretends to be a teaching assistant to teach for the tutor, these are all things that need to be recited. From the perspective of modern physics, they are just clichés. However, both Liu Bin and Wu Zong listened carefully, and the former was still silently calculating Cheng Jinzhou's formula in his heart.

"Let's replace the metal beam first." Cheng Jinzhou picked an iron bar from the table, handed it to Wu Zong and said, "Can the eye be drilled out?"

Wu Zong stroked his beard and looked at the thumb-long iron bar with some worry. He did not have a suitable 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 results you submitted to the association last time."

Lu Xu grunted in dissatisfaction, but he still stretched out a finger, found the right position and drilled into the iron bar. He saw that the place where his fingers touched was slightly red, and the iron bar was like plasticine. It penetrated deeply.

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

"Then let's get out all these dozen." When there was good labor, Cheng Jinzhou didn't want to let it go.

Liu Kuang stroked his beard and looked at the formulas listed by Cheng Jinzhou. The leader stopped working, and Wang Linghe and Xiang Xin also gathered around. Wu Zong and his two apprentices were as excited as monkeys on drugs. They wanted to jump but couldn't. They squinted their eyes and wanted to sleep, but they were also sleepy. Hazy and full of fantasy. For them, demonstrating their work in front of a fourth-level star warlock is like a small company commander meeting the commander of the army, and it feels like being awarded a medal.

"If I have time in the future, it would be better to change it to a hollow one." Cheng Jinzhou commented. The iron bar used as the experimental material is made of fine workmanship, with no burrs on the surface, let alone rust spots. With the current production efficiency, it is conceivable that the price must be very strong.

"It's difficult to control the quality of hollows." After putting aside his research work, Xiang Xin transformed into a curious baby again.

Cheng Jinzhou smiled and said: "It's not that difficult. Better scales 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 craftsmanship will definitely think of making hollow metal beams.

As Cheng Jinzhou spoke, he began to sort out the parts in his hands. Every time he wanted to modify something, he could just say a few words. Lu Xu also became a manual machine tool and helped him modify it in real time. Controlling the size of the weights and determining the accuracy of the weights is a matter of minutes, and its convenience is enviable.

Wu Zong has simply become a thug. Of course, he is the happiest at work among the few people. Now that he is asked to leave, he will be angry.

With the help of a genuine star warlock, Cheng Jinzhou's combination balance was also very fast. He also used standard weights to calculate the accuracy, and the data was 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."

This is how people have dealt with errors since the 20th century. Cheng Jinzhou curled his lips, then took out the best balance among them and said: "Wang Ling Hexing Warlock, thank you for your materials, I will give you this balance."

A balance with an accuracy of 0.07 (Note 1) is already difficult to buy in Star Warlock stores. Wang Linghe did not refuse, stretched out his hand to take it and said with a smile: "Looking at your research on torque, it is quite enlightening. "

"Where." Cheng Jinzhou chuckled. When it came to physics, he couldn't completely remember many specific places. However, although the "Mechanical Metrology" he got from the library last time only had one volume, he could remember the details in detail. It provides great supplements, and copying its contents to write one or two papers from hundreds of years ago is naturally a piece of cake.

"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 left with a smile. At least fifteen or six scales were made with materials, which was more than enough to repay the loan.

Xiang Xin stood up hurriedly and said, "Let me sort out the results of this research for you."

"Uh... why is this so embarrassing." After all, association contribution points are very valuable. He is not familiar with the paper model yet, so it would be great if someone could help him. 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 didn't refuse, Xiang Xin sat down with a smile on his face. It wouldn't take much time to collect and organize the research results, but he would have a deeper understanding of the contents. If necessary, you can also ask the original owner and learn more.

Liu Kuang didn't mind at all that his land was being used for "private work", and he sent Cheng Jinzhou and others out with a smile, specifically saying: "Remember, we will set off early the day after tomorrow."

Cheng Jinzhou thanked him again.

After leaving the door, he did not let Wu Zong go. He pulled him and said, "There are still some things I want to discuss with you."

Discussing is false, pulling a strong man is true. Wu Zong didn't mind either. Staying up late was a common occurrence for Star Warlocks. If they could learn something, it wouldn't matter if they were tired.

…

It was already midnight when he got home, and there was still candlelight in the study. Cheng Jinzhou felt a little guilty, so he took Shi Yan to settle Wu Zong first, and then walked over quietly.

"Dad." He opened the door gently, and it was Cheng Yun'an who was reading under the lamp.

"Your mother is going to bed first." Father Cheng put a bookmark between the pages of the book, put it on the table and asked, "Have you said goodbye to Mr. Liu Kuang?"

"They will also leave for the capital the day after tomorrow and invite me to take the airship with them."

Cheng Yun'an was stunned for a moment, then he said, "You won't bother me."

"No." Cheng Jinzhou shook his head firmly. When choosing between airplanes and carriages, he was absolutely determined.

"I feel much more at ease when I'm with the four astrologers. After arriving in the capital, don't cause trouble and keep a low profile." Father Cheng paused and said in a serious tone: "What you did in Hongri Village , not advisable. Yunquan has been going around for a while for your sake."

Cheng Jinzhou was silent. He killed the garrison captain in Hongrizhuang and placed him in other prefectures and counties. The army would have pounced on him long ago. But as a member of the Cheng family, the eldest son Cheng Yunquan would definitely not allow such things to happen, and the job of suppressing them was not easy.

Father Cheng sighed and said, "Go to bed early. Don't think too much. I'm going to bed too."

"Yes." Cheng Jinzhou bowed slightly and exited the house, his expression a little heavy. Before the murder, he was very angry; when he killed, he was very decisive; after the murder, he couldn't help but feel a little depressed when he thought about it. For a young man who grew up in a peaceful environment and had a normal mentality, it was not that easy to hack others to death with his own hands.

Shi Mo was waiting at the foot of the steps with a lantern, and said in a low voice: "Mr. Wu Zong is waiting for you in the wing."

"Let's go." Cheng Jinzhou grinned, realistic plans always come first.
