Chapter 552: Engineering Genius Liang Fu
Shen Zheng's face was filled with undisguised admiration.
"Master Liang is right."
"The reason why this well windlass is an equal-force lever is because the axle is too large and the power arm is too long. And the lever must be balanced to pull up the bucket, so when the power arm, that is, the length of the handle, remains unchanged, a greater force must be applied."
Liang Fu smiled and nodded: "If you want to change this 'equal force lever' into a 'force-saving lever', it's also very simple. You should just need to replace the small wheel axle, or lengthen the handle."
There was an uproar all around.
"So simple?"
"It's so simple that it can save energy? How much energy can it save? Can we feel it?"
After thinking it over, Qiao Laoliang finally admitted defeat: "I understand. I was superficial just now and forgot that the scale has two ends. I only grasped one side."
The apprentices were a little confused and came forward to ask Mr. Qiao: "Then Master...if we make the handle long enough, we can use only one finger to pump water?"
This question seems a bit "silly", and many people who haven't thought it through can't help but laugh out loud.
That shouldn't be possible, right? Everything should have its limits.
But Mr. Qiao’s answer was: “Yes. As long as the ‘leverage principle’ is correct, then it can be done.”
Shen Zheng smiled slightly when she heard that.
This is actually the theoretical meaning of "Give me a fulcrum, and I can move the whole earth."
......
If this "popular science" happened somewhere else today, some people might not think of trying it out right away. After all, it would be time-consuming and laborious to make a new axle and handle and then install it on the well windlass.
But who is here today?
A small half of them are truth-seeking "science students"!
The "science students", led by Mr. Qiao, started working right away. All kinds of tools came out at once, and the scene was very lively.
Liang Fu did not join in.
He just stared at the booklet in his hand, where he circled the words "power, power arm" and "resistance, resistance arm".
After thinking for a long time, he finally spoke to Shen Zheng: "Sir Shen, I can't figure it out. I thought that the sum of force and force arm is the force we need to use. But if so, the changes on both sides are difficult to be equal, this..."
Shen Zheng didn't expect that Liang Fu had already started experimenting with the balance formula.
She originally planned to write this formula in the physics textbook and let everyone learn it together.
After all, in her previous life, the teacher had taught her "What is force" for two classes. But today, in less than an hour, she went from force to lever principle and then to deformation lever.
It's really hard not to be confused.
Liang Fu is truly a talent selected by the country.
"It's not the sum of both sides." Shen Zheng took the booklet and said the conclusion first: "To calculate the force required for both sides here, we should use multiples of both sides."
She gave a simple example: "For example, the force of holding an egg with one hand is equivalent to the force of holding half an egg with two hands..."
"I understand now!" Liang Fu was so excited that he took back the booklet and started writing, "So the length of the power arm is equal to the length of the resistance arm. This way the lever will be balanced!"
I just saw him write a few words on the paper and draw a conclusion.
"In this way, we can calculate how to configure the length of the force arm of both parties to save the most effort when the weight is fixed and the material allows!"
"You are such a genius..." Shen Zheng was stunned.
She did not look at Liang Fu from the perspective of a later comer, but from the perspective of the present. Liang Fu was a well-deserved genius as he could understand things at a glance in such a physical environment.
"This is nothing." Liang Fu raised his head and looked at Shen Zheng. "If it weren't for your enlightenment, Master Shen, I might never understand this truth in my life."
The word "enlightenment" is here!
Shen Zheng's skin suddenly became red, and she quickly waved her hands: "Don't say that, I just..."
"No need to say more." Liang Fu interrupted her for some reason: "Sir Shen, no matter what, you are the well-deserved mentor of me, Liang Fu, and everyone in the Ministry of Works."
Mentor? !
She is just a "plagiarist", how can she deserve the title of mentor!
Shen Zheng quickly said: "No..."
"You may not know what this fixed discovery means to the Ministry of Industry." Unexpectedly, Liang Fu interrupted her after she said a word.
"When we were improving tools in the past, we vaguely felt that a lot of it was related to 'leverage', but we just couldn't find the trick, so only after countless experiments could we make the 'forces' of both sides fit together."
"And your discovery has truly broken through this layer of 'window paper', saving the Ministry of Industry a lot of effort and allowing us to avoid a long detour!"
From then on, he had a "scale" in his heart.
His expression was sincere and his words were genuine, and Shen Zheng felt an indescribable sense of happiness in her heart - she once again became a bridge between her previous life and the Great Zhou, allowing the two sides to see each other across time and space.
But she still had to say: "Sir Liang, you misunderstood, this is not..."
"Master Shen, there is no need to be modest!" Liang Fu looked at her steadily: "Except for you, there may be no one else in this world who knows this truth. You deserve to be called a mentor!"
"......" Shen Zheng couldn't tell whether he did this intentionally or unintentionally, and could only say: "What I do is just to pass on the knowledge I have learned to the world."
She deliberately emphasized the word "learned". Liang Fu looked at her deeply and finally sighed, "I know."
Shen Zheng said it so bluntly, even though Liang Fu didn't want to understand anymore, he understood it now.
But he doesn't understand.
Really don't understand.
Why wouldn't Lord Shen accept such an opportunity, such a great opportunity that would be passed down through the ages and perhaps remembered by future generations thousands of years later?
As long as she nodded in agreement, who in this world could question her? Who dared to question her?
Fame, wealth and honor were all hers. The number of people who came to become her disciples and wanted to become her disciples was probably so great that they could break down the threshold of Tongan County.
But she just didn't want to, even though I wanted to help her and send her to the top of the mountain.
After a moment, Liang Fu smiled and shook his head, tears flashing in his eyes that Shen Zheng couldn't understand: "I am obsessed..."
"What?" Shen Zheng looked at him puzzled.
In the tears, he showed his undisguised admiration for his junior: "Sir Shen, can you tell me what you want?"
"What I want?" Shen Zheng understood in a flash that Liang Fu was interrupting her on purpose.
So what does she want?
In front of them are Mr. Qiao and his apprentice craftsman, who look very nervous. There is an "insurmountable" mountain in front of them, and they are trying to climb it with the help of new tools.
In front of him were the students from the county school who were looking expectant. They had already stopped at the foot of the mountain and finally met Mr. Qiao and his group who had come with them to climb the mountain and make tools.
In front of them are Wu Quan and others who are nervous and expectant. They will hold and wait at the foot of the mountain, waiting for the news of "victory" from their predecessors.
