Chapter 962

Yang Rong, three people, each with a new physics book.

"Force, how much force is given, how much force will be fed back."

"Give the table a punch, the greater the power, the greater the feedback."

"Bang!"

Yang Rong put down the book and saw Yang Shiqi shaking his hand and smiling bitterly.

"I unconsciously hit the table. It really hurts!"

Yang Rong said with a smile, "everyone knows this truth, but he didn't summarize it. Xinghe Boguo is a great talent."

Jin Youzi frowned and said, "I can't wait to study hard. Who would be so bored to get this?!"

Yang Rong smiled and looked down to read.

"Eh! When people walk, first their feet give a force to the ground, and then the ground feedback, people can move forward by force."

"If you hit someone with your fist, the pressure is different, resulting in different effects."

Yang Rong put down the book, rubbed his eyebrows and said, "this book..."

"This book is a crooked way!"

Jin Youzi said disdainfully, "what's good to study about walking? What's buoyancy and boredom!"

Yang Shiqi frowned and said, "I think it's good. You can basically justify it by looking at his set. The discussion on lever has been applied in the wharf. Buoyancy can also be applied to shipbuilding. Look at his density. He can calculate the density through the size and weight of a thing. It's really exquisite!"

Jin Youzi looked carefully and slowly turned white.

"It's all craftsmanship. Is Fang Dehua going to change his profession?"

Yang Rong saw that he looked a little far fetched and said, "although it's a craftsman's skill, it's a practical science. Look at this. According to his mechanics and pulley lever, ordinary people can make something amazing."

……

In front of the palace in the Tai's womb, except for Zhu gaochi's family, those palace maids and eunuchs were full. Zhu Zhanji had set up a pulley block, then hooked a chair with a hook and called Wan Wan.

A pulley set consisting of a fixed pulley and a movable pulley is not very awesome, but the gentle hand is tender and tender. When the rope is pulled, it pulls the chair up, but it waves its hands and hurts.

"How many kilograms?" asked Zhu gaochi.

Zhu Zhanji was explaining the practicality of the physics book. In front of him stood a solid wood frame with a row of pulleys hanging in the middle.

Wan Wan's pulley block only uses a fixed pulley and a moving pulley, and the row on the side is empty.

"Father, thirty-six pounds."

The weight of this big chair is very frightening. Wan Wan usually can't lift it. Today, she pulled it up with a rope. For a moment, she couldn't help jumping.

"The princess is so powerful!"

Liang Zhong smiled and stared at the people on the side with threatening eyes.

Give it to our family!

"Yes! The maids and maids struggled to hold the chair, but the little princess picked it up against a rope. Sure enough..."

What is it?

The man looked at Liang Zhong and his eyes were full of begging: brother, Princess Jinzhiyuye, do we want to praise her strength? How to get married in the future!

Liang Zhong also felt wrong. He coughed and was ready to think about other good reputation, but he saw Zhu Di in a blink of an eye.

"See your majesty."

"See your majesty."

The front of the hall immediately fell down. Zhu Di squinted at the wooden shelf and said faintly, "get up."

Huang Yan and the eunuch looked at the pulley block behind Zhu Di. Huang Yan whispered, "this strange technique!"

The eunuch didn't answer with an expressionless face. Huang Yan said bitterly: "I'm still demonstrating in front of the people in the palace. Sure enough..."

"Grandpa Huang, this is the labor-saving pulley block in physics. You see, Wan Wan can lift this chair with a rope."

Wan Wan proudly said, "Grandpa Huang, Wan Wan really mentioned it just now."

Zhu Di came closer and took a look: "how much effort can you save?"

Zhu Zhanji pointed to the pulley block and said, "at present, it can save half the effort. If you can combine more pulleys, Wan Wan can lift Zhan long."

"Oh! Really?"

Zhu Di's previous impression of science was that it could not only impact Confucianism, but also let the people learn some means to make a living.

Zhu Zhanyi didn't dare to answer, but wan wan volunteered: "Grandpa Huang, Wan Wan dares! If you don't believe it, ask the third brother to try."

Zhu Di hesitated. He was worried that he might break Wan Wan's hand.

But Zhu Zhanji said confidently, "Zhan long will sit in the basket and let Wan Wan pull you."

Zhu Di nodded and said, "just try."

So Zhu Zhanji personally went to hook the rope to a string of pulley blocks, and finally handed the rope to Wan Wan.

Sitting in the bamboo basket, Zhu Zhanyi felt like a lamb to be slaughtered, dazed and helpless.

Zhu Zhanyi is almost 60 kilograms. If he wants to pull him up with the bamboo basket with a rope, Liang Zhong asks himself that it's OK, but he has to work hard.

As for wan wan

In full view of the public, Wan Wan wrapped the rope in her palm for two times, and then fell down

"Eh!"

The bamboo basket moved. Zhu Zhanyi looked silly inside. He didn't believe that his sister was pulling the rope.

Zhu Di's eyebrows moved and his hands rubbed behind his back.

"Hi!"

Wan Wan got up. Instead of squatting down this time, she began to pull the rope one by one.

The bamboo basket gradually rose. Wan Wan mastered the trick. The corners of her mouth couldn't help but tilt up and shouted, "Grandpa Huang, do you think Wan Wan is powerful?"

Chu Di's cheek moved slightly and nodded without speaking.

"Poof!"

Wan Wan was in high spirits, but didn't notice that the height of the bamboo basket had

"Ouch!"

"Poof!"

Zhu Zhanyi foolishly bumped into the wooden post on the top. As soon as the bamboo basket turned over, the man fell to the ground.

The Crown Princess couldn't help laughing when she saw it, but wan wan suddenly pulled it, but it was empty. She didn't fall down because she leaned against the rope.

"Ha ha ha!"

Wan Wan's frightened appearance made Zhu Di laugh and laugh hard.

Zhu Zhanji clapped his hands, and Jia Quan brought a large iron block with him.

"Grandpa Huang, this iron piece weighs more than 300 kilograms. We can use this pulley block to pull it up alone."

In fact, without trying, Zhu Di already believed it. He nodded slightly and squinted, but his eyes diverged.

This is a real practical study, which is not inferior to Mohism, no! Mohism is far inferior!

This is the knowledge that people can learn. If the people of Daming learned mathematics and physics, what would Daming be like?

The iron block had been hooked, and Jia Quan went to pull the rope himself.

Zhu Di took an absent-minded look, saw the iron unsteadily pulled, and then fell into meditation.

The people should be honest, which has been the judgment of the rulers for thousands of years, and it is also the unanimous requirement of the mainstream society.

What would people think if they learned these things? What plans will you have for your future?

The most important thing is, what will they think of the emperor!?

Zhu Di's eyes flashed bright.

"Grandpa Huang, Wan Wan wants to be one too!"

The iron block has risen to the highest point. Jia is not red and out of breath. He has extra strength.

Zhu Zhanji said with a smile, "it's very simple. It just needs calculation. The people of Daming learn these things. No matter where they go in the future, they are better than those foreign nationalities."

Zhu Di's eyes moved: Yes, the people of Daming must be more powerful than the other nationalities, otherwise when I go, Fang wakes up, how can they defeat those literati?

After fully understanding the nature of those honest men, Zhu Di was desperate for most scholars and civil servants.

If we follow the normal track, the future of Daming will not be different from that of Tang and Song Dynasties, but the time of extinction is different.

"What a powerful thing!"

The eunuch couldn't help sighing when he saw Jia Quan put the iron down easily.

Huang Yan said bitterly, "it's just some strange sexual skills. Can it make Daming earth shaking?"

Zhu Di's eyes were a little slow and nodded slightly: Yes, it's just some tricks that are helpful to Daming. Why bother!
