After inking for more than an hour, everyone became increasingly impatient. Xu Shenxue also knew that going too far is not enough. Amidst the complaints, he finally led everyone to the well, not forgetting to say:
"I just want to tell you, bitterness comes first before sweetness comes. Look, walk first until you are tired, and then eat watermelon..."
Xu Shenxue told fables.
Everyone, including Li Zhen, felt irritable after hearing this.
Qin Enze sighed and muttered: "I don't want to eat watermelon at all. God, it's bitter first and then sweet."
"Don't tell such childish fables anymore."
“…”
Xu Shenxue was expressionless and silent to resolve the embarrassment.
Li Zhen walked to the mouth of the well and took a look down. There were several buckets filled with watermelons.
He quickly rolled up his sleeves and grabbed the gallows at the mouth of the well with both hands.
This well is a pit well, and the main way to get water is to hang a bucket with a rope. In order to save labor, a gallows was built at the wellhead, and the rope was twisted to save labor.
This gallows is frequently lubricated and is very easy to use and saves effort. Li Zhen just grabbed the Z-shaped handle of the winch with one hand and could easily turn the winch and lift the bucket.
And when Li Zhen grabbed the handle and twisted it around, his hand loosened and he was stunned on the spot.
With a 'boom' sound, a thunder flashed through my mind.
Days of gloom and depression turned into a sudden burst of inspiration. At this moment, he caught an inspiration. At this moment, he also grabbed the drumstick that beat the war drum of Kyushu's revival!
His whole body was frozen at the edge of the well, his eyes were straight and his expression was stiff.
Xu Shenxue asked: "What's wrong?"
After a moment, a look of ecstasy appeared on Li Zhen's face, and he murmured: "I know. I know... That's it, that's it."
"I see!"
"I see!"
Li Zhen jumped up excitedly, rushed down the well platform, grabbed Liu Jinghong's neck collar, shook it hard and shouted: "I know!"
"What do you know?" Liu Jinghong looked confused.
Li Zhen laughed hysterically: "I know, hahaha, I know how it can do repeated movements. I know, I understand, I figured it out."
Everyone standing by the well was in disbelief and surrounded Li Zhen with a look of ecstasy.
"You knew already?"
"What is it?"
"what exactly is it?"
“How exactly do you do repetitive motion?”
"Have you figured it out? Oh my god, have you finally figured it out?"
“…”
"Quick, quick, call everyone in the laboratory. Quick, quick!"
Li Zhen shouted anxiously.
Xu Shenxue's face was full of surprise and uncertainty. He also realized the seriousness of the matter and shouted: "Hurry, go quickly."
Fang Hanxian jumped out and ran out.
He rushed to the Kyushu Institute of Physics in a hurry, pushed open the door, overturned the table suddenly, and roared: "Don't even sleep!"
A thunderous roar woke up all the people who had fallen asleep. Everyone looked straight at Fang Hanxian, who usually did not dare to speak loudly.
Fang Hanxian shouted in a trembling voice: "Quick, go to the well. Master Li said he knew, he discovered it. He said he knew the answer to how to solve the problem of repeated movement of the piston. Quick, everyone go to the well."
With a 'buzz', the whole laboratory exploded instantly.
No one said anything, they all got up and ran out like crazy.
At the door, Qi Lengzi also stood up, watching a large group of people running out, and murmured: "Are you going to crack it?"
He fanned his thighs and ran forward, forgetting to drop the bench legs he was holding.
The movement in the laboratory alerted other students passing by. They saw this group of people who were crazy and unreasonable, and each one of them rushed out of the laboratory with nervous expressions on their faces, extremely curious in their hearts.
"What's wrong?"
"Since this group of people were stationed in the auditorium, no one has ever come out. They can't be moved, why are they all running crazy today?"
"Did...did you discover it?"
"Did you solve the problem?"
"What is it?"
"Quick, come and have a look!"
"It's by the well in the playground. Come on, come on."
“…”
The people waiting by the well heard a loud "rumbling" sound in the distance, and couldn't help but turn their heads to look.
However, he saw that the dozen or so people leading them were all students from the Kyushu Institute of Physics, and each of them looked nervous and anxious. He ran this way like crazy, so fast that even the long-legged Qi Zi couldn't catch up. Every one of them is like crazy.
After them, there was a large group of students rushing from the direction of the teaching building. There were thousands of people in the crowd.
All of them were alarmed by the abnormality of Kyushu Institute of Physics and came over to watch the excitement.
In the classroom where classes were taking place, I heard the noise outside, and everyone lay on the windows and looked down. Listening to those calls, the teacher lecturing was surprised and said: "Such a big movement, could it be that they have solved that particularly unsolvable problem? This is a big deal. You study by yourself, I'm going to take a look."
With that said, the teacher who was giving the lecture threw down his books and ran downstairs.
The students in the classroom were silent for a moment. In an instant, everyone stood up and ran wildly downstairs.
The entire Fuxing University was in chaos because Li Zhen's words caused a sensation in the Kyushu Institute of Physics. The students who had been worried about the Kyushu Institute of Physics were alarmed by the anomalies in the Kyushu Institute of Physics.
Li Zhen said that everyone from the Kyushu Institute of Physics would come, but... the whole school came.
He stood on the well platform and looked at the crowd of people below, all looking at him with blank eyes.
In the silence, Fang Hanxian, the most introverted person, became furious at this time. He stamped his feet and yelled: "What on earth is going on?"
Li Zhen came back to his senses, with a maniacal smile on his face: "It took two weeks, but today I finally made a breakthrough. I finally know how to solve the problem of repeated movement of the piston."
"How to deal with it?"
Everyone from the Kyushu Institute of Physics gathered around and asked nervously.
And everyone except Kyushu Institute of Physics stared with big eyes and blank faces. Can't understand…
What piston moves repeatedly? What is a piston? What does repetitive motion mean
Li Zhen led everyone to the edge of the well, holding the winch of the gallows with one hand: "Look, when I shake the gallows, the winch will rotate. We all thought in the wrong direction. We were just thinking about how to exert force on the piston. To make the piston move repeatedly. But what we should be thinking about is how to make the piston move repeatedly, whether it is applying force to the piston or something else."
Qin Enze's eyes brightened and he asked, "What then?"
Everyone outside the Kyushu Institute of Physics was stunned.
What's the meaning? What force? What does it do? Can't understand!
Li Zhen pointed to his right hand: "If my arm represents the piston, and my physical strength represents the thrust of the steam. Then the upper part of my arm is always moving in a straight line, and the piston moves in a straight line in the cylinder. Linear motion. But my arm has a joint from the elbow, so the force of the linear motion is transmitted to the forearm, and then transmitted to the winch around the center of the circle of the winch. The force changes, and it is immediately converted from linear motion to circular motion. . Circular motion is applied to the winch, thereby producing rotational motion."
"We should not constantly imagine how to change the piston. What we imagine should be how to use the piston to change the operation of force. According to the conservation of energy, energy will continue to be converted. And we ignore the conversion of force. It can convert a straight line The motion is converted into circular motion. We were wrong before and should not imagine changing the piston. We should imagine adding another device to the piston to change energy and convert energy."
"And this device, maybe it's called... a crank connecting rod!"
“…”
The words fell.
All the staff at Kyushu Institute of Physics were stunned on the spot, looking at their arms and then at the imported winch.
Silence fell.
After being silent for a long time, Liu Jinghong opened his mouth exaggeratedly and laughed wildly with an extremely hoarse voice: "You are a genius!"
Everyone in the Kyushu Institute of Physics immediately gathered around, lifted Li Zhen up, threw him into the sky, then caught him, and then threw him into the sky again.
Everyone was laughing like crazy.
"You are a genius!"
"Crank rod!"
"Hahahaha, crank connecting rod. No, it should be called arm connecting rod, haha,"
"Doesn't this solve the problem of changing exercise behavior? Hahaha."
"We're going to make it!"
"We are finally on the way to success!"
“…”
Thousands of people from the whole school came after hearing the news and quietly watched the 33 people partying at the entrance of the well. Confused.
Crank connecting rod? Straight line motion? Circular motion? Conservation of energy
None of them understood. They had no idea what the people from the Kyushu Institute of Physics were talking about and what they meant.
"Go back to the lab. Quick!"
“…”
With a hearty howl, 33 disheveled people were so excited that their whole bodies trembled. Amidst the uncontrollable laughter, he pushed away the crowd crazily and rushed back to the laboratory.
Thousands of people in the whole school looked at this group of demonic people in silence.
Everyone’s thoughts: Suddenly, I’m so envious of them…
They have a carnival that belongs only to them.
