He looked at the experimental device in disbelief and said, "A speed of more than 100 kilometers hits the wall? I don't understand bullying, right? What kind of international joke is this?"

A small steel ball falls from a height of meter on the glass. How can it be compared to a car adjusting a wall?

He mocked, "As you say that, which piece of glass can withstand the impact? Is it okay to hit it with a car?"

Isn’t this a fantasy?

Hu Zhixing was a little helpless.

They all explained that the contact surface of rigid collision is extremely small and the contact time is extremely short. He is not only an amateur, but also fails to pass the physics level in high school.

It's really a talk with the duck...

Speaking of which, her glass substrate is not very useful?"

Chiba Oda hesitated for a moment and said, "It may not be of much use as a glass substrate."

but……

The P City Glass Group can produce ultra-thin glass sheets with such good performance. If used as other places, it is hard to say.

But at this time, he decided not to touch Hiroo Oki, otherwise he would definitely be scolded for being useless again.

He himself felt that he was useless, why was it developed by the Chinese?

If it were Country M, Country D or other Western countries, at least it wouldn’t be so embarrassing!

After leaving Oki Hiroo's lounge, the expo organizers have already started to conduct experiments.

Ultra-white, ultra-thin, etc. can be used as monitors and glass on optical instruments, which are classified into the same category for experiments.

In order to show fairness and the experiment is open and transparent, all manufacturers' glass samples are numbered in order, and then they are arranged in a row to conduct the experiment. After all the experimental data are released, the corresponding manufacturer of the number is announced.

This can also reflect fairness to a greater extent and prevent undercover operations.

The first is the mechanical strength test, and the organizer chose the impact resistance experiment.

After the sample glass is fixed on the impact test bench, the computer-controlled 50 grams of steel balls fall from a certain height, and starts to fall freely from 50CM, hitting the glass, and pass the test without damage.

After passing, change the glass sample again and adjust it to a new height.

There are more than 50 glass companies participating in this competition. Performing experiments in public and impartially in public will naturally attract many technical people to watch.

Of course, if you don’t understand, you can also watch the fun.

In the first experiment, only two companies failed.

Although the experimental requirements at the Industrial Expo are much higher than usual, those who can participate in the competition still have a few tricks, and the elimination rate is not surprising.

The steel balls were raised by 5CM, and no one was eliminated.

The experiment was carried out in an orderly manner, but some people who were not aware of the arts were wondering: "How strong can such a small ball fall down? When will the 5CM5CM be lifted?"

As soon as these words were spoken, they attracted a lot of chuckles.

Hu Zhixing was a honest person and explained to the man: "Don't underestimate the impact force. The steel ball falls freely and the rigid collision with rigid glass has a small contact surface and a very short contact time, so the impact force generated per unit area is quite large.

When the ball falls freely from about one meter, the instantaneous impact force the glass bears is equivalent to driving a car to hit the wall at a speed of more than 100 kilometers.

Glass is a rigid and fragile item, and once it exceeds the bearing limit, it will instantly crack and there is no room for buffering."

As soon as these words came out, the man widened his eyes.
