Xiao Ming, from Class 2 and Class 3, is the representative of the physics class in his class. He considers himself extremely smart, so he organized his friends to build several models based on mechanical principles over the weekend, and named this series of models Star Ruins.

On Monday, Xiao Ming moved the Star Ruins to the class, which troubled many classmates. Xiao Ming was in the limelight for a while.

"Hey, hey! Let me give you a strategy!" Seeing everyone's confused looks, Xiao Ming clapped his hands confidently and said.

After everyone heard what Xiao Ming said, they all gathered and sat in a circle.

"Actually, it's just about using the fewest lines to keep the balance of the model!"

Xiao Ming cleared his throat.

"Ahem, first of all, to understand the star ruins model, we must first understand the small ball model," Xiao Ming said as he took out a bracket, a small ball and a red thread from his schoolbag.

"How to connect the bracket and the ball into a whole with the least number of wires and maintain balance?"

"It's very simple, I think everyone knows it."

Without waiting for anyone to answer, Xiao Ming had already suspended the ball on the stand with a red thread and placed it on the table.

this? ? What does it have to do with the Star Ruins? Everyone whispered to each other.

Xiao Ming looked at everyone's confused expressions, and a mysterious smile appeared on his lips.

"I know, everyone doesn't understand what this has to do with the model of the star ruins. Don't worry, let's take the next step."

Xiao Ming took off the small ball, took out another C-shaped model from his schoolbag, and connected it to the stand with a red wire.

"If it is this kind of model, one of the suspension wires will not be able to pull it, and it will fall to the lower left. Everyone should be able to see this.

So I put my hand on the lower left side. "

"Then how can we do it without using hands?" everyone asked.

"It's easy, just add two more wires."

Xiao Ming smiled and took out two more red threads from his schoolbag.

"These two are called balance lines," Xiao Ming said. After tinkering with the model a few times, he placed something on the table.

"Dang, Dang, Dang," he stretched out his left arm and made a magician's classic opening move.

Put this thing on the table.

"What is this thing?"

Xiao Ming took out the model of the star ruins.

"It's it"

"That's it too"

"This is the first model of the Star Ruins. In fact, the principles of all models are the same."

Xiao Ming jumped to the podium and drew two circles on the model diagram.

"All models can be divided into four parts

1. Bracket (red circle)

2. Suspended objects (blue circle)

3. Suspension line (each model has only one, corresponding to the first line in the c-shaped model)

4. Balance lines (the number varies depending on the model, corresponding to the last two lines in the c-shaped model)

And the rules of the game are

In simple mode,

The first level: distinguish the lines, cut off the excess balance lines, retain the suspension lines and the minimum required balance lines

The second level: adjust the angle of the hanging object, and then connect the suspension line and the minimum required balance line

In the complex mode, you need to install the anchor points yourself, and you can explore by yourself with fewer lines.

As for the operation, it’s all in the settings, so please review it! "

After Xiao Ming finished speaking, he jumped off the podium and returned to everyone,

He put his hands on his hips and raised his face,

"Is everyone clear?"

Contrary to what Xiao Ming expected, there was no applause or answers, only whispers.

The study committee member wearing glasses was the first to break,

"Ah, Xiao Ming, I remember you said this thing is a tensegrity structure, a tensegrity or something like that. You have said so much, but did you explain what a tensegrity is? Self-supporting, self-stressing, etc... You didn't talk about it, did you? ?”

As soon as he finished speaking, class monitor Xiao Hong also said: "Also! When explaining the C-type model, how can you say that everyone can see it? Is this a rigorous academic attitude? You can't draw a force diagram. ? I’m afraid the physics class representative won’t be able to draw anything that’s not a particle, right?”

The math class representative also jumped out and shouted: "Yes, what are the names of suspension wires and balance wires? Each wire is prestressed, why is the one at the bottom called a suspension wire? It's unprofessional! This will mislead everyone. of."

"I, I..." Xiao Ming's head began to sweat, "This, this is the game...the game's strategy. It is no problem to play and pass this game. I, I have been thinking about it for a long time, and I am afraid that it will be too much like a lecture. No one is watching.”

"Ha, Shina! That's because you don't know how to speak!"

Monitor Xiao Hong stood up, jumped onto the podium, and looked at Xiao Ming with a contemptuous smile.

Then he looked at everyone under the podium, and they smiled knowingly at each other,

Xiaohong said, "Quick, everyone come up with real strategies!"

Everyone lowered their heads and started groping in their schoolbags. After a while, everyone lifted up a green book, like a forest of hope and a pot of spinach.

Xiaohong jumped out and raised the green book with her right hand. Only then did people see clearly that it was structural mechanics!

Xiaohong took a few steps forward and walked in front of the camera. Facing everyone in front of the screen, she smiled and said,

"Dear players, structural mechanics is the real strategy!"

“Everyone shout with me!

"Structural mechanics! Structural mechanics! Structural mechanics!"
