Chapter 898

Li Yun solemnly said: "Your Majesty, this bridge is absolutely feasible. This bridge seems to be an iron cable bridge, but in fact, it applies the theory of arch bridge incisively and vividly."

"Yellow mouth child, it's nonsense. It's clearly a piece of iron cable bridge and beam bridge. What's the matter? It involves an arch bridge." a waiter from the Ministry of work angrily scolded.

Li Yun smiled and said, "you can't see the trace of the arch bridge if you look at it like this, but if you look at it upside down!"

Li Yun did not go on, but raised the model and turned it upside down, impressively turning it into a replica of the arch bridge. The so-called Weishui bridge impressively turns the arch bridge upside down.

Li yunlang said: "The fact that the arch bridge is solid and feasible has been verified for thousands of years. There is no doubt about this. My husband's vein has been immersed in this for thousands of years. As for the cognition of the arch bridge, it can be said to give up who I am. The Weishui bridge takes the steel cable as the arch and hangs the bridge body one by one. It seems that the bridge body is extremely heavy, but it spreads its strength on the steel cable and applies the theory of the arch bridge in turn It is said that it is a marvelous work. From the perspective of the grass people, this bridge is feasible in theory. "

It can be said that there is no rival in the world in terms of arch bridges. One is Li Chun's Zhaozhou Bridge and the other is Li Yun's Qujiang arch bridge. It can be said that this has been personally confirmed.

"This is only theoretically feasible, and in this way, the success or failure of the bridge is all tied to a small steel cable, which is very ridiculous!" the waiter of the Ministry of industry sniffed, which immediately attracted the laughter of many ministers.

Li Yun was immediately flushed with excitement. He wanted to argue, but he couldn't talk about it.

"Ling Shilang, the steel cable you mentioned is not a small one, but a super strong steel cable composed of hundreds of high-strength steel wires. This steel cable is three feet thick." Merton stepped out proudly and solved the siege for Li Yun.

Ling Shilang said with a sneer: "mohou takes it for granted. You know, the Weihe River in the north of Chang'an city is more than a mile wide. With such a long length and the weight of the bridge, how can it be borne by a mere steel cable."

He had never seen such an absurd thing in his life in the Ministry of construction.

Merton laughed and said, "turning the impossible into the possible is the magic of Mohist ink technology. Moreover, Mo once saw a word that Mohist sages encouraged future generations in Mozi's Secret works. Mo also asked you for advice."

"Mozi's Secret works" Li Yun's eyes lit up. He had heard about the legendary Mozi's Secret works for a long time and didn't expect to hear Merton's oral statement.

"It's hard to cross the ocean with a penny. People paddle and start a big sailboat.

A small tree, weak without wind and rain, hundreds of miles of forest, side by side, resistant to the cold of the year. "

Merton's Langsheng voice, which was full of cadence, suddenly became silent. The words were simple and unadorned, but the philosophy contained in them was simple, easy to understand and very profound.

Li Yun's eyes lit up and he became more interested in the secret works of Mozi in Merton's mouth. These words are simple and clear, but they contain the concept of Mohism.

Merton continued: "Han Feizi once said that he took one hand alone. Although he was silent, it was difficult to sound alone. However, during the military parade that year, tens of thousands of people applauded.

As we all know, one chopstick can be gently broken, and ten chopsticks can be tightly held in a group, but they can't hurt half of them with all their strength. Now, the same is true of Mohist steel cables. The most popular Mohist machinery is the kilo arm. One person's strength is enough to lift a kilo of weight. In addition to Mohist ink technology, the steel wire rope composed of small steel wires is of great merit 。

The suspension cable designed by the Mohist School for the construction of the Weishui bridge is three feet wide, just like tens of thousands of steel wires tightly held together, and the strength it can bear is multiplied by ten times and one hundred times. Not to mention that one suspension cable is not enough, the Mohist school has prepared four steel suspension cables for it at once. Let alone that the current carriage is only carrying 5000 kg, even if it is increased by ten times, there will be no damage Problem. "

Merton said, and there was a silence in the hall,

"One chopstick was slightly broken and ten chopsticks were tightly held together. This statement really contains great truth." Li Shimin sighed.

Merton's theory seems incredible, but it is not difficult to understand. I'm afraid ordinary people have no choice but to cut them into sticks the size of chopsticks. I'm afraid even a ten-year-old child can easily break them one by one, and the steel suspension cable of Weishui bridge is this principle.

Li Yun is even more thoughtful. He has always believed that Mozi's success today only depends on Mozi's Secret works. However, Mozi's ability to find the secret skill of building bridges from the inspirational words of Mozi's sages makes him admire it.

"Moreover, there is only one Weihe River. Among the rivers in the Tang Dynasty, it ranks the top 20 at most. If we can't conquer the Weihe River, let alone the Huaihe River, the Yellow River and even the Yangtze River, which are wider and more complex, now the brick roads in the world are unblocked, but they are blocked by the river, so it is imperative to build a bridge." Merton said proudly.

In an instant, Merton found the best basis for the construction of Weihe River Bridge technically and theoretically.

Many courtiers nodded. The Weihe River Bridge opened the northern passage of Chang'an City, which is of great importance, but it is still inferior to the bridges across the Huaihe River, the Yellow River and the Yangtze River. The Weishui bridge built today is only the least difficult. Only by building this bridge can it be possible to build a longer and more complex bridge in the future.

Seeing that Merton was about to convince everyone, suddenly a voice suddenly appeared, but the matter of Weishui bridge was in crisis again.

The Chamberlain of the Ministry of household proudly listed and said, "not to mention whether the bridge is feasible or not, it is difficult to achieve by using materials alone. In addition to underwater, steel is mostly used on the surface of the water. In this way, how much steel and money will be consumed, I'm afraid the government's finance is also difficult to bear."

Li Shimin was stunned and couldn't help looking at Dai Zhou. Dai Zhou also said with a bitter smile: "Your Majesty, although his Highness the prince reformed the post station to save a sum of money for the imperial court, there are too many places to spend money in the Tang Dynasty. I'm afraid he can't afford to spend too much money to build the Weishui bridge."

Li Shimin frowned, turned his head and looked at the Ministry of work and said, "what about the Ministry of work? The prince has not allocated enough money to the Ministry of work before."

Zhang Liang, the minister in charge of the Ministry of work, stood out and said, "Your Majesty, although the crown prince has allocated a batch of money, this year the Ministry of work has built a number of brick roads and overhauled the Yellow River and Huaihe River while the people were serving corvee. Now the Ministry of work has little money in its hands."

The Weishui bridge is dominated by Mohists. Mohist village provides raw materials, and Mohist Xiangfu takes charge of the construction. However, the Ministry of work can't get involved at all, so it's naturally unwilling to pay for it.

Li Yun and Tian Mou could not help but change their faces. He did not expect that there were so many people in the chaotang who did not welcome the Mohists. This time, the construction of the Weishui bridge was said to benefit the country and the people, but it was difficult.
