Don’t say that Su Xiao was shocked.

The catcher Yi Xingyu was shocked.

The audience was shocked.

It took several seconds before someone stood up and applauded.

The audience burst into applause, and it was given to Yi Cheng and Su Xiao. This was really a thrilling contest between the pitcher and the hitter.

...

Su Xiao walked out of the field with some depression, and until now he still didn't understand what happened to the last floating ball.

After he was struck out, City No. 1 Middle School lost its backbone.

The two subsequent hitters continued to be struck out by Yi Cheng.

Mingfeng Middle School won the game as it wished.

...

The sun sets west.

It was not until this time that the clouds in the sky broke through a ray of light.

It was like a long red silk spreading on the ground.

Yi Cheng's figure was pulled out to a long and slanted.

He turned around and stared at the scoreboard in a daze.

Suddenly I felt that these three games were so difficult.

If they did not have the 3 points they had obtained before and the zero points they lost when Yan Fei defended to the death, they might not have been able to win the final victory.

After the game, the two teams gathered, saluted each other, and then bowed to the audience and left the venue.

...

On the way back to school in the car, everyone seemed extremely excited.

For the freshmen in the first year of high school, today is their first game.

For Yi Cheng, today is his first official game victory now.

On the way back, Yi Xingyu asked him strangely, "Why did he not hit the ball when Su Xiao played the last ball, which was obviously a straight ball that was very easy to play in the center of the red heart?"

"Ha ha ha ha……"

Yi Cheng held his stomach and smiled so hard that he leaned back and forth.

After smiling for a while, he looked at Yi Xingyu with anger on his face, and then he curled his smile.

"Because, for you, it's a straight ball, but for Su Xiao, it's actually a floating ball."

"Floating balls on the top?" Yi Xingyu was stunned for two seconds, "Damn, when did you learn this unique skill?"

"Are you an idiot? Where in the world can anyone throw a floating ball?"

"But, I clearly see..." Yi Xingyu stopped talking.

He has read some books about baseball, as well as TV and animation.

The statement about floating balls is like this—

When the ball is thrown out, it will produce upward lift due to rotation and friction with the air.

If this lift is strong enough, it can offset the effect of gravity and form an upward floating ball.

Once the pitcher can throw such a ball, the hitter basically has no way.

Yi Cheng looked at him angrily, "Do you want to say that the ball can be generated by the influence of lift? For example, the slower the ball speed, the slower the ball speed, the easier it will fall. On the contrary, the faster the ball speed, the stronger the lift will be generated?"

"Isn't it?" Yi Xingyu felt very uncomfortable when he said it.

"It's OK in theory." Yi Cheng smiled, "Things calculated based on the formula of fluid mechanics:

The formula for the lift coefficient of the sphere can roughly be roughly estimated to be 1.5x(rxw/v) or 0.090.6x(rxw/v). When (rxw/v) is greater than 0.1, we use the following formula, otherwise it is the previous formula.

Assume r is the radius of the ball and w is the speed of rotation.

Let's set it faster, 50 revolutions per second, which is 3000rpm, which is about 314rad/s.

In order to make the lift (cxax0.5xρxv^2) larger so as to compete with gravity and make the ball float upward, we must set the variable numbers as much as possible.

Assuming that the air density ρ is 1.394kg/m^3, the ball speed is as fast as 160km/h.

The value of (rxw/v) is 0.25, 0.090.6x0.25=0.24, and we can get a baseball lift of 1.342 Newtons flying at 160.

In addition, the gravity is 1.39 Newtons."

"So do you understand, it's hard to throw a ball in an ideal state."

"I don't understand." Yi Xingyu shook his head, thinking to himself who can understand this?

"Simply put, if we want to throw a floating ball that overcomes gravity, we need to increase the ball speed to above 166 and the rotation speed to above 50.

The world's top pitcher has a speed of basically between 20 and 40, and it's hard to reach 160."

When he said this, Yi Cheng suddenly paused.

A monster appeared in his mind—

Guo Beichuan.

If you look at it this way, if you can throw the ball to 170 like Guo Beichuan, if you can improve it and increase the speed of the ball, you might be able to really throw the floating ball.

Fortunately, Guo Beichuan is still in elementary school now.

He probably didn't expect to become the fastest man in the world in the future.

At this point in time, the fastest speed of active professional baseball pitchers is only 164 per hour.

So Yi Cheng said these words.

"So, the floating ball only exists in the legend." Yi Cheng coughed and concluded.

This time Yi Xingyu understood.

"You are so boring. What's there to show off? Wouldn't you just say that?"

Yi Cheng smiled and didn't say anything.

"But why do you say that in Su Xiao's opinion it is a floating ball?" Yi Xingyu captured the key to the problem.

"There are short memories of human bodies." Yi Cheng continued to explain, "When I was sitting on the bench before, I learned something-

Su Xiao has rare dynamic vision.”

"Well, there is something happening, so that guy has great eyesight. Generally, bad balls can't deceive him. He can always catch the ball and hit the ball." Yi Xingyu said seriously to Yi Cheng, "His strike rate was the highest in high school last year, with a play rate of nearly 60%. It is said that many professional baseball clubs are already contacting him."

Yi Cheng tsk his lips and heard a sour smell from Xiao Hei's words.

"But what I'm using is Su Xiao's dynamic vision."

"What the hell? Can dynamic vision be exploited?"

"Did you find out that because Su Xiao has dynamic vision, he will stare at every ball."

"So I told you not to always shoot ok balls at that time. If he remembers it, it will be easily shot out." Xiao Hei said.

"I haven't finished speaking yet," Yi Cheng was not very satisfied with him interrupting himself. He leaned against the bus seat back with his hands in his arms and said lazily, "I just hope he keeps his eyes on it."

“My speed ball has a distinct feature, which is that it will suddenly hang to the lower left corner when approaching the plate.

Su Xiao stared at my ball, once, twice...

Over time, his eyes adapted to the ball path of the speed ball.

When his eyes remembered this change in the ok ball-

At this time, if a straight ball suddenly comes, it will be difficult for Su Xiao’s eyes to adjust from his previous memory, and his brain will feel--

The ball seemed to float up suddenly."

Yi Xingyu paused for two seconds, and his eyes widened in surprise.

"Damn, is it true?" Yi Xingyu looked at him in disbelief, "You have calculated this? Are you still an individual Yi Cheng?"

Yi Cheng smiled, didn't say anything, turned over and closed his eyes.

The moonlight outside is bright.

The city lights also lit up.

His body slowly swayed slightly as the car moved.

This is called the mystery of the human body.
