The Red Era, the Opening University Speech

Chapter 3 No way, are you serious?

Facing the expectant gaze of the beautiful girl, Li Mu felt a little hot in the middle of winter.

At this moment, a message alert sounded in his mind.

Ask: "Lee, do you want to play games? I'll be online now!"

Li Mu replied immediately: "I'm not playing games. I need your help with something. Can you send me a copy of the principles and design of the electric drill?"

This strange request made Ask puzzled:

"Aren't these all available if you search online? Okay, wait a minute."

Although he didn't understand, Ask still chose to help Li Mu.

After a while, he sent me a document.

Li Mu clicked it.
Can open!

Li Mu breathed a sigh of relief.

He searched quickly and soon found the principle and design drawings of the electric drill.

"Li Mu?"

Li Mu was distracted by what happened to the beautiful girl and was a little surprised.

Li Mu quickly spoke up and said, "I think there is not much room for improvement in weight. My experience will not be of much use to you."

"I hope everyone will focus on other aspects, such as making the hand drill faster, more energy-efficient and more durable."

There was a slight commotion from below, as if some people were dissatisfied with Li Mu's tone.

"Isn't Li Mu a bit arrogant? Just reducing the weight a bit, but he dares to say that no one can improve it!" muttered the man with bottle-bottom glasses.

"Yes, I admit that Li Mu is amazing, but no matter how amazing he is, can he be more amazing than the professor?"

"I think Li Mu is getting carried away..."

The people below echoed and talked a lot.

Several teachers also frowned slightly, thinking that Li Mu had made the mistake of being arrogant.

"Not mature enough!" a professor sighed regretfully.

"When you said there's no way to reduce the weight, do you mean you think you've done your best?" the pretty girl asked curiously.

Li Muxian explained: "Of course not. Instead of spending more time on reducing weight, I hope everyone can improve other aspects."

Li Mu paused, then began to read from the information:

"As we all know, in a hand drill, the motor is the core component, which converts electrical energy into mechanical energy and drives the rotary head to rotate."

"During the rotation process, the magnetic fields generated on the stator and rotor in different directions of power supply interact with each other, making the hand drill have both forward and reverse functions, which greatly facilitates our production and life..."

The pretty girl frowned at Li Mu's statement, and asked a common sense question: "Wait a minute, what did you say next?"

Li Mu was suddenly interrupted and was a little confused.

Is there something wrong with Ask's information?
But he read it word for word according to the information!

Li Mu hesitated and repeated: "It is the conversion of electrical energy into mechanical energy..."

"It's not here. You said it's the interaction between the magnetic fields of the stator and the rotor that makes the electric drill have the function of forward and reverse rotation!" the girl said firmly.

She actually heard it clearly, but...she just couldn't believe it.

Can a hand drill be reversed?
Li Mu: ???
As a liberal arts student who had never done any housework, he had never even operated an electric drill himself. Before reading the information, he certainly didn't know that this thing could be used on both sides.

There was a buzz of discussion below.

Li Mu looked at the noisy crowd in a daze.

The pretty girl continued to ask, "The electric drill obviously can't be reversed, why do you say it can be reversed?"

Finally, someone couldn't help but question loudly:
"Isn't it common sense that an electric drill cannot be reversed? How could Li Mu not understand this?"

"So how did he come up with the improvement of the hand drill?"

……

The teachers sitting in the front were frowning.

Only the professor in the middle, who was wearing a Mao suit, was thoughtful: "Reversal, the different directions of the current lead to the reversal function. This design idea is very clever!" "It is feasible in theory!"

"This Li Mu has a talent for engineering design!"

The beautiful girl waited for Li Mu's answer, and the doubt in her eyes grew heavier as time went by.

Sweat dripped down Li Mu's forehead.

Poor him, a liberal arts student, how could he know that the electric drills of this era can only rotate forward and not reverse!

It's just a hand drill!!

Just when the atmosphere was at a stalemate, applause suddenly broke out.

"Pah~pah~"

Professor Wei stood up, clapped his hands vigorously again and again, and said in a loud voice:

"As a student of Beijing Institute of Technology, Li Mu has improved the electric drill on his own, so of course he will remember these basics!"

"I'm afraid it's because I suddenly had an inspiration on stage just now, so I had a new idea for improvement and said it subconsciously!"

"I was wondering why Li Mu was a little absent-minded before. I wanted to criticize him after the meeting, but now it seems that he deserves a reward!"

"This spirit of constantly thinking about problems is worth learning for each of us!"

After the professor in the Zhongshan suit finished speaking, everyone suddenly understood.

The thunderous applause sounded like waves.

Several students who had just suspected Li Mu lowered their heads in shame.

"Fuck, you can even make this up for me?" Li Mu was surprised and happy.

He almost wanted to pretend to faint just now.

"So that's how it is." After hearing Professor Wei's words, all the doubts in the beautiful girl's eyes disappeared.

Yes, how could Li Mu not know such basic principles?

Wait until the applause stops.

Professor Wei continued, "Li Mu, the principle you proposed is feasible, but do you have any ideas on how to change the direction of the current?"

"This..." Li Mu pretended to be in deep thought and was a little afraid to speak.

But other people have already imagined it, so it would be inappropriate for him to play dumb at this time.

After hesitating for a moment, Li Mu said:
"In fact, we can reverse the winding of part of the stator coil to change the direction of the current flow, thereby changing the magnetic field in the rotor and achieving reversal."

"This design is very clever!" Professor Wei exclaimed.

He only needed to think about the principle briefly to be sure that there was no problem.

But the principle alone is not enough. No matter how good the drawing is, it must be able to be implemented.

At this time, the students below were also aroused by Li Mu's theory.

Those who draw drawings draw drawings, and those who turn pages turn pages.

"I think we can add a motor, one for forward rotation and one for reverse rotation." The boy who was drawing the blueprint said loudly.

The girl flipping through the book shook her head and said, "You're increasing the weight and cost of the electric drill. Why not just produce two types of electric drills?"

……

Listening to the students' heated discussions, Professor Wei nodded repeatedly with satisfaction, and looked at Li Mu, the one who caused all this, with admiration.

Fuck, what are you looking at me for!
Li Mu was feeling uneasy. He had said everything he could say. He couldn't just demonstrate it on the spot by rubbing an electric drill with his hands, right?
At this time, the pretty girl suggested: "Professor Wei, I think we can do an on-site experiment. The principle is not complicated. If we work together, we can do it quickly."

No, are you serious?

Li Mu on the stage was feeling very uncomfortable.

He is good at talking about theory, but he is useless when it comes to putting it into practice.

"Professor Wei, let's go move the experimental materials!"

When several boys who were discussing the reversal theory heard what the beautiful girl said, they immediately volunteered to move things.
