Chapter Twenty-Nine: The Waterwheel

The eldest grandson who returned to his residence blushed a little, it was too embarrassing today.

But this problem always has to be solved.

"Childe, are you still annoyed by what happened last night?" Wang Tie Dan looked at the unhappy eldest grandson and said.

Something was wrong with the eldest grandson who was exercising today, and the sword kept slashing at the stake.

Wang Tiedan's face hurt when he saw it, this guest is money, you are a loser, the sword is used for playing, not for chopping, phew, follow this kid to learn these messy words, the sword is used to stab, not to split, and your sword is worth dozens of times.

"What do you say, this is despised by your general Chi Guoguo." The eldest grandson still looked depressed.

"Childe, have you forgotten the waterwheel, it's very common in the south." Wang Tie Dan reminded.

"yes, I didn't think of that." The eldest grandson's face suddenly realized.

"No, your general still has this knowledge, since he didn't say it, it means that the waterwheel must also be problematic, and it is impossible to promote it on a large scale here." Soon the eldest grandson denied this.

"Can't you go and ask the general?" Wang Tiedang said.

"Do you think I didn't lose enough?" The battle is somewhat neat.

"Count me in trouble." Wang Tie Dan was also depressed, I have never given you ideas before, this is not easy to come out once, and I actually complained, should.

"Yo, what's wrong, brother?" Ma San walked in.

This period of time together made Ma San also have a hot fight with them.

"Third brother, what are you holding in your arms, why is it so fragrant?" Ge Feng asked.

"This, authentic haggis, eat this early here." Ma San replied.

"Oh, lamb, I like it." These Ge Long and Ge Feng are authentic carnivores, and this greasy meat is the best breakfast when they get up in the morning, and there is really no one with this heavy taste.

"It's not lamb, it's offal." Ma San corrected to.

"What is chop?" Ge Feng's existence makes people feel that their IQ is far beyond the level of normal people.

"Offal is the internal organs of animals, like the large intestine, the small intestine or something." The eldest grandson said coldly.

"Yo, the eldest grandson is an expert, I know this." The two of them didn't care about the retching two Ge brothers on the side.

This internal organ is the death hole of the two brothers.

"Serve me a bowl, not lamb lungs." Changsun Yu continued.

The three of them wiped out a large bowl of haggis and returned to the topic just now.

"Why haven't I seen a watermill here?" The eldest grandson asked?

"I know that." Ma San'er replied.

"Three years ago, I was probably forced to delay it again, this was a great drought, and the general sent people to Guanzhong to invite a few craftsmen to come over and build a water wheel." Ma San'er recalled.

But the craftsmen were unwilling, saying that there was no bamboo. It's so far from the south, where can I find bamboo? The general gave the order, saying that it was replaced with wood. Ma San took a sip of wine.

"Since the craftsmen knelt down, they said that this ancestor had a legacy and that he could not make a waterwheel out of wood. Naturally, the general did not believe it. The craftsman could only make a wooden waterwheel, and when the waterwheel entered the water, it turned well, and the general was ready to reward these craftsmen, but these craftsmen insisted on it. No one thought that after three days the waterwheel would be overturned, and the general had no choice but to send them a coil and some rewards to let them go. Ma San was still the head of the general's personal army at that time, but he knew all about these things.

"So that's what happened, but fortunately I didn't lose someone again." The eldest grandson was a little glad that his mood was actually saved so well.

People are so strange that they will be annoyed by some things that have happened, and they will be glad about some things that have not happened.

"Do you know the details here?" Wang Tiedan was very curious about this matter.

"If I knew, I would be a general, and I would have to send you chops." Ma San said angrily.

"There's got to be a reason for that." I know that I don't believe in those strange things like ancestral teachings, and since I know the truth about Thanksgiving, I don't think Thanksgiving is a good thing anymore.

And our ancestors used gods to explain these things that could not be explained well, and it was just a river god and a sea god, and there was actually a well god, which was really unacceptable.

"Ge Feng, go find me a piece of wood." The eldest grandson decided to take matters into his own hands to uncover the mystery.

"Oh, do you have any requirements for this wood, Childe? For example, how big, how heavy, and what kind of wood is used...... "Ge Feng has been tricked like this by Changsun Tang before, so Changsun Tang is purely digging a pit to bury himself.

"All I need is a piece of wood." The eldest grandson unceremoniously interrupted Ge Feng's words, and Ge Long also patted Ge Feng.

"Oh, okay, I'll go." Ge Feng hurriedly left.

The eldest grandson was thinking, if this waterwheel could really only be made of bamboo, it would be impossible to transport bamboo from thousands of miles away in order to make a waterwheel, and the price would be too great.

But why can't it be replaced with wood?

"Here, Childe, the wood is here." While the eldest grandson was pondering, Ge Feng took the wood.

Changsun Tang casually threw the wood into the washbasin, looking at the ups and downs of the wood, at this moment, Changsun Tang is not a person, at this moment Archimedes and Newton are possessed, at this moment Changsun Tang is really not a person, Changsun Tang is not a person.

"I see." The eldest grandson roared, and everyone around him jumped.

The principle is actually very simple, wood is a solid structure, much heavier than the hollow structure of bamboo.

The force of the entire waterwheel is limited, and the heavy wood overwhelms the waterwheel that moves in a circular motion quickly, and naturally the life of the waterwheel will not be long.

There are two ways to solve this problem: one is to reduce the weight of the waterwheel, such as using bamboo instead of wood, but this obviously does not work; The second idea is to increase the load-bearing level of the waterwheel.

The eldest grandson didn't expect that this little inconspicuous waterwheel would actually involve these things, and while sighing at the wisdom of the ancients, he secretly scolded: "If you don't listen carefully when you take physics class, now such a small problem can't be solved, now you know that learning is useful, don't you still sleep in class in the future?" ”

Knowing the principle of the problem does not mean that the problem can be solved, but the general direction is there, and all that is needed is some details.

"Can you tell me more about the structure of the waterwheel?" The eldest grandson asked Ma San for details now.
