Chapter 1187: The Victory of Physics

Brothers, the ranking of the monthly ticket list has been falling all the way! The jazz thinks it can still be rescued, please vote!

...

When Zhu Di and his party arrived at Jubaoshanwei, Fang Xing and Zhu Zhanji were already waiting.

Zhu Di got off his horse, looked at the soldiers lined up to greet him, and asked, "Did Zhanji have no homework today?"

This question made the civil servants heave a sigh of relief.

As long as Zhu Di still insists on Confucianism first, then any science is just a joke.

"Grandpa Huang, my grandson stopped her homework for half a day today."

Zhu Zhanji walked into the barracks with Zhu Di in the past, and said, "Grandpa Huang, there is a grandson in Zhu Gui. If someone wants to use the things invented here in the future, they have to pay, otherwise the grandson has invested in it all these years." Everything is gone."

Zhu Di frowned and said, "What money do you charge for things that are beneficial to the country and the people?"

Jin Youzi and Lu Zhen who were behind looked at each other, and couldn't help smiling.

His Royal Highness, the grandson of the Emperor of Ming Dynasty, actually cares about money like a businessman, it really is... unprecedented!

Zhu Zhanji said with a smile: "Grandpa, if there is no return on the investment, who will research new things regardless of the cost in the future? We wait for others to come up with it, and just imitate or go directly?"

Zhu Di said: "You are right. The year before last, you said you had no money, and you borrowed a lot from me. The Ministry of Industry also has it?"

Zhu Zhanji said embarrassingly: "Grandpa Huang, the Ministry of Industry just took a lot of ore, and my grandson has already paid it back at the beginning of this year, and only you are still owed."

The money owed by his grandson to his grandfather was an interesting thing for Zhu Di, so he frowned softly and went all the way to Zhu Fang's side.

Zhu Fang changed into a new outfit today, and when she saw Zhu Di panicked, she quickly brought the craftsmen to salute.

"No need to be cumbersome, just show me that car."

Zhu Fang was so excited that she took Zhu Di to the edge of the railroad track step by step, pointed at it and said, "Your Majesty, look, this is the railroad track. Horse-drawn carts run on it, which saves a lot of money and can load a lot of goods." .”

Zhu Di squatted down, tapped the rails with his fist, touched the crossties, and asked, "If there is such a thing in the Water Transport Wharf,

Many people are redundant, right? "

After getting up, Zhu Di saw a pile of iron blocks piled up at the end of the railroad track and a pulley block erected, so he nodded and said, "This is what the pier looks like."

Zhu Zhanji smiled and said, "Grandpa Huang, you should take a look first."

"good!"

Zhu Di got up, Fang Xing asked Zhu Fang to drive the carriage over.

The carriage is very large, and it has four wheels, pulled by four horses.

Is this illegal?

The thought flashed by, and Lu Zhen smiled wryly.

This is a truck, not a puller.

"Your Majesty, these horses are just ordinary draft horses, but they are made more solid because the cart needs to be loaded with goods."

Zhu Di went over to check in person, and the officials joined in the fun, and the railroad tracks and carriages were full of people for a while.

Zhu Di is very familiar with the horse, and he can distinguish it at a glance. He mainly checked the carriage.

"Well, let's get started."

The carriage went up the railway track along the specially left slope, Zhu Fang yelled, and the craftsmen lifted the iron block with pulley block easily, and put it into the carriage.

"Grandfather, an iron block weighs eighty catties."

Zhu Zhanji proudly watched the pulley block lift the iron block easily.

One piece, two pieces, three pieces...

Yang Rong was already numb, and Jin Zhong asked loudly from the side: "How much is Xing Hebo?"

Fang Xing didn't count, and said indiscriminately: "I don't know, I have to fill it up in the end, it's probably a hundred yuan."

I go! Eight thousand catties!

Zhu Di had a deep impression on the wharf. When he led the army to start Jingnan, he set off from Tian/Jinwei.

Tianjin Wei was called Zhigu at that time, and the goods from the south were transported here by water and then transported to the north.

Zhu Di couldn't help but look nostalgic when he remembered that when the army set off, there were ants densely packed on the wharf carrying goods and luggage.

If there were such means at that time, how many civilian husbands could be saved!

War is burning money, but also burning people.

Regardless of ancient or modern times, the army's luggage is transported step by step by manpower and animal power.

So what about this horse-drawn railcar?

When the carriage was full, a man came and sat in front of the carriage. With a flick of the whip, the four harness horses moved together.

"It's moving!"

Eight thousand catties is probably just a number for civil servants, but after seeing the amount of iron blocks, they all doubt whether the four horses can pull them.

With four horses, two on each side, it was a bit difficult at first, but after the carriage moved, the movement became easier.

The coachman sat on an extra seat on the front of the car, holding a whip in his hand, and after a yell, the carriage gradually accelerated.

"Run away!"

Yang Shiqi has ridden countless times in carriages and ox carts, and knows the speed of the carriage.

But this carriage has pulled eight thousand catties of goods, and it can run so easily and so fast. If there is nothing, what if it is pulling people?

While he was thinking wildly, Yang Shiqi heard someone exclaim: "I'm going to rush out!"

The speed of the carriage is getting faster and faster, but the rails are so long, if it rushes out, it is estimated that people and horses will have to overturn.

Yang Rong glanced at Fang Xing, but the situation was calm.

Pretending to be mysterious!

"Gah..."

At this time, there was a strange sound from the carriage in front, and then the carriage began to slow down.

Slowly, the carriage finally stopped a little before the end of the track.

"Huh!"

Liu Guan, who has better eyesight, said in surprise, "The driver didn't even get out of the carriage, how did the carriage stop?"

China's carriages and ox carts have a long history, but the way of braking is very shabby.

The first method of braking is that before going downhill, the driver puts down a stick connected to the carriage, and pulls a rope on the stick. The driver runs to the back of the car to pull the rope, and the stick rubs against the wheels. This is the brake.

The second is to rely entirely on a "brake stick" at the back of the car. When the driver wants to slow down, the driver gets off and tilts the car backwards, and the stick will rub against the ground to achieve the purpose of slowing down.

But the coachman didn't get out of the car just now!

After getting closer, everyone saw that the coachman was still in the car, and their interest suddenly increased.

Most of these civil and military officials traveled on horseback, but their families had to travel by car.

Over the years, there have been many incidents of startling horses. The coachman had no time to react, so he could only pull the reins desperately.

If you can brake, how much trouble can be saved!

Fang Xing watched with cold eyes, and saw Liu Guan, Jian Yi, and Jin Youzi walking over, then squatted down and carefully looked at the wheels, looking for the brakes.

The others, especially Wu Xun, including Lu Zhen, all gathered around the carriage, carefully watching the structure of the carriage, and some went to check the rails.

"What's the point of this?"

The four horses were so easy that people thought two horses would be fine.

Zhu Fang was squeezed outside, sweating profusely: "Your Majesty, this is..."

"You come in and say."

Everyone got out of the way, Zhu Fang came in, pointed to the rails and wheels and said, "Look, Your Majesty, the wheels are cast and have an outer edge, which coincides with the rails below, so that the running resistance is very small."

"resistance?"

Jin Zhong was stunned.

Zhu Fang nodded and said: "Yes, it is the resistance. The heavy objects are pressed on the wheels, and the friction between the wheels and the ground is the resistance. This kind of track coordination can minimize the resistance. Once the speed is increased, the inertia will be great, and the horse will be affected. The strength is also small..."

Jin Zhong still looked confused, Zhu Fang helplessly picked up a stone and rubbed it on the ground, saying: "If there is no rail, the wheels of the carriage will rub against the ground like this, creating a lot of resistance. But the rail and the track are relatively smooth, and the resistance is can be reduced."

"Furthermore, with four wheels, the horses don't have to bear weight, and they only need to pull the cart. This is not only stable, but also saves horsepower."

Looking at a group of bewildered courtiers, Zhu Di said blankly, "Who taught these?"

Zhu Fang didn't think about anything else, and blurted out: "This is the science taught in the academy."

silence!

The officials who were still wandering around the carriage just now seemed to have been immobilized and remained motionless.

This invention that can save time, manpower and cost is something in science?

Zhu Zhanji said: "Grandpa Huang, this principle is in the physics book. As long as you study hard and work hard, most people can understand it. Maybe someday someone will invent something more powerful."

Is everyone Yao and Shun?

The ministers had complicated eyes and tangled hearts.

Zhu Di said calmly: "Everyone, take a look and see what else this car can do."

Ever since, the uncomfortable group of officials began to "research" unwillingly.
