Chapter 958 The Magical Pulley Block, the Complicated Zhu Di

The three of them, Yang Rong, each have a newly published physics book.

"Force, how much strength is given, how much strength will be returned."

"Punch the table, the greater the force, the greater the feedback."

"Boom!"

Yang Rong put down his book and saw Yang Shiqi wryly smiling.

"My officer hit the table without knowing it, it hurts!"

Yang Rong said with a smile: "Everyone knows this truth, but they haven't summed it up. Xing Hebo is indeed a great talent."

Jin Youzi frowned and said, "It's too late for me to study the scriptures, who would be so boring to do this?!"

Yang Rong smiled, then looked down at the book.

"Hey! When a person walks, first the feet give a force to the ground, and then the ground gives feedback, and the person can use the force to move forward."

"When you hit someone with a fist, the pressure is different, and the resulting effect is also different."

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

"This book is a crooked way!"

Jin Youzi said disdainfully: "What is there to study about walking? What buoyancy is there, boring!"

Yang Shiqi frowned and said, "I think it's good. Look at his set, which can basically be justified. The discussion about levers has been applied in the wharf. Buoyancy can also be applied to shipbuilding. Look at his density. Calculating the density by the size and weight of an object is really ingenious!"

Jin Youzi looked at it carefully, and his complexion gradually turned pale.

"It's all craftsman's skills. Is Fang Dehua going to change his career?"

Yang Rong saw that his expression was a bit far-fetched, so he said: "Although it is a craftsman's technique, it is a practical study. Look at this. According to his above-mentioned mechanics and this pulley lever, ordinary people can do it." Come up with something surprising."

...

In front of the hall in the crown prince's womb, except for Zhu Gaochi's family, the court ladies and eunuchs were all crowded. Zhu Zhanji had already set up a pulley block, then hooked a chair with a hook, and called Wanwan.

A pulley block composed of a fixed pulley and a movable pulley is not very powerful. Wanwan's small hands are delicate, and she pulls the chair up by pulling the rope, but it hurts to wave her hand.

"How many catties?" Zhu Gaochi asked.

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

However, Wanwan's pulley block only uses a fixed pulley and a movable pulley, and the row on the side is empty.

"Father, thirty-six catties."

The weight of this big chair is frightening, Wan Wan usually couldn't lift it, but today she pulled it up with a rope, and she couldn't help but feel a little excited for a while.

"The princess is amazing!"

Liang Zhong smiled, and stared at the people around him with threatening eyes.

All praise our family!

"That's right! The servants struggled to hold the chair, but the little princess lifted it up with a rope. It really is..."

What is it?

The man looked at Liang Zhong, his eyes were full of pleading: Brother, the princess is golden and jade leaves, do we want to praise her for her strength? How are you going to get married in the future!

Liang Zhong also felt something was wrong, he coughed dryly, and was about to think about other reputations, 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 frame and said calmly, "Get up."

Huang Yan and the eunuch looked at the pulley block behind Zhu Di, and Huang Yan said in a low voice, "This is an amazing skill!"

The eunuch remained expressionless and did not respond, Huang Yan said resentfully, "I'm still demonstrating in front of the people in the palace, it really is..."

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

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

Zhu Di walked closer and took a look: "How much effort can it save?"

Zhu Zhanji pointed to the pulley block and said: "Currently it can save half of the effort, if we can combine a few more pulleys, Wan Wan can lift Zhan Qian.

"

"Oh! Really?"

Zhu Di's previous impression of science was that it could impact Confucianism, and it could also teach the common people how to make a living.

Zhu Zhanqian was a little afraid to respond, but Wanwan volunteered: "Grandpa Huang, Wanwan is so brave! If you don't believe me, call the third brother to try."

Zhu Di hesitated a little, he was worried that he would break Wanwan's hand.

But Zhu Zhanji said confidently: "Sit in the basket and let Wanwan pull you."

Zhu Di nodded and said, "Just try."

So Zhu Zhanji personally hooked the rope to a string of pulleys, and finally handed the rope to Wanwan.

Zhu Zhanqian sat in the bamboo basket, feeling like a lamb waiting to be slaughtered, dazed and helpless.

Zhu Zhanqian weighed about sixty catties, and Liang Zhong thought it would be okay if he wanted to use a rope to pull him up together with the bamboo basket.

As for Wan Wan...

Under the watchful eyes of everyone, I saw Wanwan put the rope in her palm and twisted it twice, then her body fell...

"Huh!"

The bamboo basket moved, and Zhu Zhanqian looked foolishly inside, not believing that it was his sister who was pulling the rope.

Zhu Di frowned and rubbed his hands behind his back.

"Hi!"

Wanwan got up, this time she didn't squat down, but started to pull the rope one by one.

The bamboo basket gradually went up, Wanwan mastered the trick, the corners of her mouth couldn't help but raised, and she shouted: "Grandpa Huang, do you think Wanwan is good?"

Zhu Di's cheeks moved slightly, and he nodded without speaking.

"puff!"

Wan Wanla was in high spirits, but she didn't notice that the height of the bamboo basket was already...

"Ouch!"

"puff!"

Zhu Zhanqian bumped into the wooden pillar on the top in a daze, and when the bamboo basket overturned, he fell to the ground.

The princess couldn't help laughing when she saw it, but Wanwan pulled suddenly, but the pull was in vain, and she didn't fall down because of the rope.

"Ha ha ha ha!"

Zhu Di couldn't help laughing out of Wanwanhou's frightened appearance, and burst into a rare laugh.

Zhu Zhanji clapped his hands, and Jia Quan came over with someone carrying a large iron block.

"Grandpa Huang, this iron block weighs more than three hundred catties. We can use this pulley block to pull it up by ourselves."

In fact, there is no need to try, Zhu Di already believed it, he nodded slightly, and then squinted, but his eyes were a little distracted.

This is real practical learning, not inferior to Mohism, no! The Mo family is far behind!

This is the kind of knowledge that the common people can learn. If the common people of Ming Dynasty learned mathematics and physics, what would this Ming Dynasty be like?

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

Zhu Di glanced absent-mindedly, seeing the iron ore being pulled unsteadily, and then fell into deep thought again.

The common people should be simple, this is the judgment of the rulers through the ages, and it is also the unanimous requirement of the mainstream society.

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

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

There was a flash of light in Zhu Di's eyes.

"Grandpa, Wanwan wants to make one too!"

The iron block has risen to the highest point, Jia is not red all over, is not panting, and looks like you have enough energy.

Zhu Zhanji smiled and said: "This is very simple, it just needs to be calculated. The people of Ming Dynasty have learned these things, and no matter where they go in the future, they will be better than those foreign races."

Zhu Di's eyes moved slightly: That's right, the people of Daming must be stronger than the foreigners, otherwise, after I'm gone, how could Fang Xing and the others beat those literati?

After fully seeing the nature of those honest and gentlemen, Zhu Di has despaired of most literati and civil officials.

If it follows the normal trajectory, the future of Daming will not be different from that of Tang and Song Dynasties, but the time of its demise will be different.

"Amazing stuff!"

The eunuch couldn't help admiring when he saw Jia Quan put down the iron block with ease.

Huang Yan said resentfully: "It's just some weird and obscene skills. Could it be possible to turn Da Ming upside down?"

Zhu Di's eyes softened slightly, and he nodded slightly: That's right, it's just some kits, which are helpful to Daming, so why bother!
