Xiao Qiang was very happy that he actually pried a stone that was much heavier than himself.

So he lay triumphantly on the plank and couldn't get down, showing his snow-white body to these people.

Hu Ye went up and kicked Xiaoqiang to the bottom.

Xiao Qiang shook his body at this time, flicked the dust away, and returned to Hu Ye's feet.

Although everyone was a little curious, they were not surprised, because they also knew this principle, and the closer the stone below was to that side, the less effort would be on their side.

"Boy, that's what you're teaching us? It's not your style. Ruan An said slowly, he is an architect, and he is very familiar with the principle of leverage, but with his understanding of Hu Ye, if it was just this, Hu Ye would not let everyone come to class.

"Ahem, it seems that Grandpa Ruan still understands me, this is just an appetizer." Hu Ye coughed, then moved the stone under the plank for a moment, and then sat down on the other side of the plank.

"I believe in leverage and labor-saving, everyone basically knows the way of this matter, but how much effort will be saved, I believe you don't necessarily know the way, right?" Hu Ye sat on the wooden board and shook it while speaking to the students.

After hearing this, some of the students shook their heads, saying that they did not know the Tao.

"Actually, this is very simple, just like the scale you usually use to buy things, the farther away the scale, the heavier the weighed thing. The farther away from me the stone below, the less effort I have. I'm the scale, the stone is what I want to buy. And this whole lever is a big scale. The stone below is a fulcrum. The weight of the stone and the weight of mine are known conditions. Your assignment today is to find out the formula for the labor-saving effect of this lever. Hu Ye stood up as he spoke, lifted the cage containing the mice, and looked at the half-understood students.

A group of students are in the clouds, they only know how much effort is saved, but they don't know how much effort is saved, and now Hu Ye asks them to find a formula, that is to say, how much effort can be calculated, which is a big challenge for them.

Hu Ye knew that this question was not difficult for Ruan An, but the other three old men were difficult, and they usually read medical skills and sage books. Little is known about the way of Gewu. It's even more impossible to find this formula.

"Boy, don't you say this is what I should teach in architecture, why did you let you teach it?" Ruan An said angrily that this algorithm is often used in construction. When else was he going to tell his students? But I don't need to talk about it now. Because Hu Ye has already done it for him.

"Brother cough, Grandpa Ruan, I said it. The four disciplines of Qingtian Academy complement each other, and students can't learn only one subject, so I talk about it, and I also help you teach students by the way, which is equivalent to helping you reduce your burden, and you should thank me. Hu Ye said with a smile.

Ruan An blew his beard and glared, it was the first time he had seen such an arrogant person who was so arrogant, and he wanted to thank him.

"Hmph, since you can talk so much, then talk more and share more for me." Ruan An said angrily.

"Ha Luha, Grandpa Ruan doesn't have to be angry, my Gewu has a lot in common with your building, and this one may be very useful to your building, maybe it can be used when building hospitals and theaters in the future." Hu Ye smiled, and then lifted the mouse in his hand.

Those students don't have the same question that Hu Ye left just now, how can they find the formula that Hu Ye said. But seeing that Hu Ye seemed to be ready to fight that mouse again, they didn't think much about it, and first came to see what Hu Ye was going to talk about.

"Do you know the strength of this mouse?" Hu Ye carried the basket and asked loudly.

"Isn't it just a mouse? What strength can be used, and what else can it do other than make a hole? A disciple said disdainfully.

Hu Ye shook his head when he heard this, after the scene just now, these people still fixed their eyes on the present, without a little divergent thinking.

"Someone in the Celestial Empire once said that if you give him a fulcrum, he will be able to lift the earth. The earth refers to the ground beneath our feet, and the same applies to this mouse. Hu Ye said quietly.

"What! Cocking the ground beneath our feet? Are you sure that person isn't crazy? "The first reaction was Ruan An, as far as he knew this matter best, when he was usually engaged in construction, he often encountered the principle of leverage, so he was very good at saving effort.

But as Hu Ye said, it is impossible to warp the ground under his feet, and even if it is labor-saving, it is impossible to save it to this point.

And Hu Ye's last sentence, saying that the mouse can also pry up the ground under his feet, made Ruan An feel that Hu Ye was talking nonsense, the strength of a mouse is enough to support the things that can move half a catty, not to mention the land under his feet.

Not only Ruan An didn't believe it, but the rest of the students and the rest of the three old men didn't believe Hu Ye's words.

If he hadn't lived in the 21st century, Hu Ye would have thought that the person who said this was a madman.

But as a young man in the twenty-first century, Hu Ye felt that Archimedes was not a madman, and if he was really given a fulcrum, he could really pry up the earth.

"Ahem, although this thing is a bit exaggerated, it works in theory, but it is a little troublesome to implement." Hu Ye said loudly.

"Now I'm going to do an even more amazing experiment for you." Hu Ye said and picked up the long rope.

"Do you think this rat can pull this stone up?" Hu Ye asked.

Not surprisingly, everyone shook their heads, if a mouse could pull a hundred pounds of large stones, they would all become strong men.

"How is it possible, a mouse can't even pull a pound of things, how can it pull up that big stone, teacher, are you kidding?" One student said curiously.

"Yes, it's true that a rat can't pull the rock, but I'll use these wheels to get the rat to lift the rock, believe it or not?" Hu Ye said confidently.

Now the people of the academy are boiling, even if they use a lever, this mouse will not be able to lift this stone.

Hu Ye also knew that it was unrealistic to let the mouse use a lever to lift the stone, because it would require a very long plank, just like what Archimedes said about priing up the earth, which was unrealistic.

But Hu Ye didn't think about using levers, there is something that is easier to calculate than levers, that is, pulleys, so he asked these students to find these wheels.

"Boy, are you kidding? How much strength can this rat have to lift that big rock? Ruan An also didn't believe it, if that was the case, wouldn't it be easy for a person to lift a large stone of several thousand catties? Will it be so troublesome to repair the house in the future?

Lou Ying and Xiao Jiuxian didn't speak, they were not familiar with this aspect, but common sense told them that it was impossible for this mouse to lift the stone.

Li Yuanshan is also tight-lipped about this matter, he doesn't comment on this matter, because he has already seen Hu Ye's magic, if he refutes Hu Ye now, if Hu Ye really lets this mouse lift the stone later, wouldn't he be very faceless? You can't be embarrassed in front of this kid.

"Grandpa Ruan, it's still the same sentence just now, if you give it a fulcrum, it can also pry the earth, not to mention this stone." Hu Ye said quietly, then looked at the look that everyone didn't believe, and then had an idea, "I think in order to increase the appreciation, let's make a bet." ”

"Bet?" All the students were stunned, when did the teacher start gambling?

Only the corners of Lao Qian's mouth jumped, and he said in his heart that these people were probably going to be pitted by the young master again, because he had never bet on Hu Ye and lost.

The last time I made a bet was when I came to the Cloud Inn, I bet that Yin Changlong would be admitted to the Jinshi, although it has not yet been fully revealed, but Yin Changlong's admission to the Jinshi is basically a sure thing, I didn't see those scholars who bet with Hu Ye, and they came to the Nameless Mansion to visit Yin Changlong in three days, and asked him to intercede with Hu Ye, so that he could cancel the gambling contract.

So Lao Qian believes in Hu Ye unconditionally, even if Hu Ye bets that he can pry up the earth, Lao Qian will bet without hesitation that Hu Ye can pry up.

But others don't think so, because a mouse lifts hundreds of pounds of stones, which is completely contrary to common sense, and this bet is a little sorry for himself.

"Boy, let's talk about the bet first." Ruan An is also eager to try, although he doesn't believe what Hu Ye said, but he is still a little afraid of Hu Ye's unpredictable ghosts, if the stakes are not big, he can make a bet.

"Quite simply, if the rat lifts up the big rock, I'll win. Actually, I won't have anything, you just need to keep this mouse well, and these students can feed it with their own food, and I believe it won't eat much. If this mouse can't be lifted, I will lose, if I lose, I will do all the complicated work of the academy this month, and I will help wash the clothes of these students, and underwear and underwear are no exception. Hu Ye said loudly.

When they heard the underwear and underwear, the faces of the few female students turned red, and they laughed and scolded Hu Ye in a low voice.

Xiao Qiang's ears were sharp, and naturally he couldn't escape its surveillance, so he yelled at the female students a few times, telling them not to scold their eldest brother for being a hooligan.

The female students are shy, but the male students are bold, they are worried that the clothes in the academy have to be washed by themselves, this Hu Ye will be sent to the door, and this month can finally be relaxed.

So a group of students agreed without thinking about the exam, what are they afraid of, even if they lose, they are just raising a mouse, and they can still starve and lose weight? (To be continued......)

PS: Dear scholars, due to the use of tablet code words two days ago, there was a confusion between Qingtian Academy and Qingshan Academy, and now it is changed to Qingtian Academy. Please forgive me for the inconvenience caused by this, and I respect Huohua.
