Xiao Ya's explanation has already involved the problem of aerodynamics, Lin Tian casually explained: "The aerodynamics of a car is not as complex as that of an airplane, and the main core problem is air resistance, which is related to the drag coefficient. Pinshu.com "

"The drag coefficient of civilian production vehicles is generally between 0.28 and 0.40, which reflects the amount of air resistance, and the two are positive. Those who follow Formula 1 cars will probably know that the drag coefficient of Formula 1 cars is much higher for civilian production cars. ”

"Its drag coefficient is about 0.70 to 1.1, and some are even as high as 1.3, why is the drag coefficient of F1 cars so high? This goes back to the question of Xiaoya just now, because the speed of the car is very fast, in order to ensure the grip of the four wheels, it is necessary to obtain more downforce from the wind resistance, so that the wheels are close to the ground, so that it will not lose control at top speed. ”

"As for how to get downforce from wind resistance, it's a matter of body construction, and it's a big deal. Going back to the question of drag racing, drag racing people are generally keen on modding cars, but most of them are very amateurish. ”

"When many people modify sports cars, they like to install aerodynamic packages such as rear wings to improve wind resistance, handling and dynamics. ”

"Actually, this seems ridiculous, because the real professional modification must go through the wind tunnel laboratory test, and now every big racing team in the world has its own wind tunnel laboratory, each wind tunnel laboratory is worth tens of millions of dollars, and it is also equipped with special aerodynamic engineers and computer analysis systems. ”

"You know why the underground drag racers don't dare to race the track, and these professionals, they are as ignorant as three-year-olds. ”

Lin Tian talked eloquently, and everyone was stunned, and several people's eyes widened. They are all top students in science and engineering, and they can understand the topics of these majors, and it is because they can understand them that they are amazed by Lin Tian's insight.

Xiao Manxuan knows Lin Tian, under Lin Tian's seemingly unruly appearance, he is full of arrogance in his bones, and this arrogance is not pretended. People's knowledge, strength, and ability are the pillars that support pride.

There is a good saying, those who have strength are called bullshit, and those who have no strength are called stupid.

He Xiaofei is well-informed, but at this time she also sighed: "I often like to explain this and explain that for you, but now it seems that in front of you is just an axe." ”

"He squad leader doesn't have to be humble, boys and girls focus on different areas, boys are more inclined to focus on military, weapons, economy, automobiles, science and technology, games and so on, everyone has their own strengths. Lin Tian didn't care.

"Anyway, I think it's a waste for Brother Lin not to study engineering. Qiao Xiaoyi said.

Lin Tian just smiled and didn't reply, Jiang Xiuying also said that it would be a waste not to study medicine, and Zhou Lao also said that it would be a waste not to learn jewelry, if he would learn something, he would have to do it with the immortal doppelganger technique.

The car finally left the city, and the mountains began to be visible in front of it, and the road was not as clean as in the city.

"Brother Lin, is the car behind Zhao Weitao them?" Qiao Xiaoyi pointed to the rearview mirror and said suddenly.

Xiao Manxuan and the others also got up and looked back, and sure enough, they saw a red Ferrari approaching quickly, and the convertible shape was the most eye-catching.

"That's right, it's their car. Xiao Manxuan said, very unhappy, because the dangerous driving just now made everyone worried.

The person in the back car also found Lin Tian's car, and Liu Yuansi was pleasantly surprised: "Brother Zhao, I finally chased after you." ”

"Do you want to chase after it?" Xiao Na and Xiao Ya also asked, but they didn't have the confidence they had before, and they had just been dumped away, so where did they dare to be arrogant.

Zhao Weitao had a cold face, accelerated with one foot on the accelerator, and quickly chased after him, but this time he did not overtake immediately, but followed behind Lin Tian's car, as if waiting for the opportunity.

"Mr. Lin, I found the red Ferrari just now, do you want to get rid of them?" Xiao Ya suddenly asked Lin Tian.

The car is equipped with a 360-degree all-round camera, as well as the detection of radar waves and infrared recognition, which are hidden and can provide all road conditions for the artificial intelligence Xiaoya, because it itself has unmanned driving functions.

Lin Tianyan showed a hint of an interesting smile, and said lightly: "Don't shake it, don't they like convertible sports cars? ”

"What are you going to do?" He Xiaofei asked carefully, she knew now that Lin Tian was crazy, it was really exciting enough, but it was too exciting, and the little heart couldn't stand it.

Mu Binglan glanced outside the car, and her face showed a relieved smile, as if she had guessed what Lin Tian was going to do.

Lin Tian didn't do anything exciting, just lightly took the steering wheel and pulled over the car, as if to give way to the Ferrari behind.

Zhao Weitao and the others were stunned by Lin Tian's behavior, and Xiao Na said strangely: "He won't have a conscience to find out, right, and actually give way to us?"

Several people were still puzzled, and Zhao Weitao was still hesitating whether to go over, but in the next second, they didn't have time to think about it.

Because it has been out of the city, the road is not very tidy, there is a lot of sand and dust on the side of the road, Lin Tian leaned aside, the sand and dust on the ground was suddenly brought up, and the billowing smoke and dust drifted backwards.

Because the Ferrari is open-topped, in just a few seconds, the dust blew into the car, several people were caught off guard, and they all sucked a few mouthfuls of dust, and the bright and beautiful clothes and hairstyles were even stained with a layer of yellow dust, how embarrassed and embarrassed.

"Lin Tian, you deceive people too much!" Zhao Weitao suffered this crime, and he couldn't guess Lin Tian's intentions, so he immediately scolded, and didn't care if he had an image or not.

But as soon as he opened his mouth, a few mouthfuls of dust were sucked in, Zhao Weitao could only shut up and quickly raised the roof of the car. After the roof of the car was raised, it was considered to be isolated from dust, but several people and the beautiful car interior were stained with a lot of dust.

"Brother Zhao, they are too bullying. Xiao Na and Xiao Ya wiped the dust from their mouths and cried coquettishly, but they didn't expect how they humiliated others before.

Zhao Weitao didn't say a word, his face was even more ugly, now he didn't dare to overshoot, he could only eat ash in the back, he was originally playing majestic with an open top, but the majesty was not played, but the dust was eaten.

"Hahaha......" Lin Tianche burst into laughter, and the girls all laughed, but Qiao Xiaoyi was an honest man who smiled helplessly, as if he felt that he should not be wronged.

Lin Tian won't pay attention to him, this guy is too kind, even if he was almost hit by a car, he can still help the other party say good things, this kind of realm, Lin Tian can only sigh to himself.

If people don't offend me, I won't offend anyone, if people offend me, they will be repaid three times, this is Lin Tian's principle, Confucius said, repay grievances with virtue, how can we repay virtue? Confucius did not advocate repaying grievances with virtue.

Kindness should not be endless tolerance!
