Xiaoya's explanation has already involved aerodynamics. Lin Tian casually explained: "The aerodynamics of a car is not as complicated as an airplane. The main core problem is air resistance, which is related to the wind resistance coefficient."

"Now the wind resistance coefficient of civilian production cars is generally between 0.28 and 0.40, which reflects the size of air resistance. Both are positive. Those who are concerned about Formula 1 cars may know that the wind resistance coefficient of F1 cars is high. a lot of."

"Its wind resistance coefficient is about 0.70 to 1.1, some are even as high as 1.3. Why is the wind resistance coefficient of F1 cars so high? This is back to Xiaoya's question. Because the speed of the car is very fast, in order to ensure the four-wheel grip, Get more downforce from wind resistance and keep the wheels close to the ground so you don't get out of control at extreme speeds. "

"As for how to get downforce from wind resistance, this involves body structure issues, and it's further away. Back to the problem of drag racing, drag racing people are generally keen to modify cars, but most of them are very amateur."

"Many people like to install aerodynamic kits such as rear wings when modifying sports cars to achieve the purpose of improving wind resistance, improving handling performance and dynamic performance."

"In fact, this seems ridiculous, because the real professional modification must pass the wind tunnel laboratory test. Today, every large racing team in the world has its own wind tunnel laboratory. Each wind tunnel laboratory is worth tens of millions of dollars. A special aerodynamics engineer and computer analysis system are also needed. "

"Know why the underground dragsters dare not race on the track. Get up with these professionals, they are as ignorant as three-year-olds."

Lin Tian talked eloquently, and said a few words to everyone, and several of them widened their eyes. They are all talented students in science and engineering. These professional topics can be understood, because they can understand, they are surprised by Lin Tian's knowledge.

Xiao Manxuan knew Lin Tian. Under Lin Tian's seemingly unruly appearance, he was full of arrogance. This arrogance was not pretended. Human knowledge, strength and ability are the pillars that support pride.

There is a saying that a strong pretender is called Niubi, and a weak pretender is called shǎbī.

He Xiaofei was well-informed, but at this time also said with emotion: "I often like to explain this to you, explain that, now it seems that in front of you, it is just a trick."

"Leader He doesn't have to be modest. Boys and girls focus on different areas. Boys tend to pay more attention to military, weapons, economics, cars, technology and games. Everyone has their own strengths." Lin Tian didn't care.

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

Lin Tian just smiled and didn't reply. At the time, Jiang Yingying also said that it was a waste to not study medicine, and Zhou Lao also said that it was a waste to not study jewelry. If you want to learn anything, then you must use the immortal art Row.

The car finally got out of the city. You can see the mountains in front, and the road is not as clean as in the city.

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

Xiao Manxuan also stood up and looked back. Sure enough, he saw a red Ferrari approaching quickly. The shape of the convertible was the most eye-catching.

"Yes, it's their car." Xiao Manxuan said, very upset, because the dangerous driving just now made everyone nervous.

The person behind the car also found Lin Tian's car. Liu Yuansi was pleasantly surprised: "Brother Zhao, finally chased."

"Would you like to chase it?" Xiaona and Xiaoya also asked, but they had no confidence and had just been thrown away. How dare they be arrogant.

Zhao Weitao froze with cold, accelerated his throttle, and chased quickly, but this time instead of overtaking immediately, he followed Lin Tian's car and seemed to be waiting for the opportunity.

"Mr. Lin, you found the red Ferraris just now, do you want to get rid of them?" Xiaoya asked Lin Tian suddenly.

The car is equipped with a 360-degree omnidirectional camera, as well as detection radar waves and infrared recognition. These are hidden, and can provide artificial intelligence Xiaoya with all road conditions, because it itself has a driverless function.

Lin Tian's eyes showed a funny smile, and said lightly, "Don't shake them, don't they like roadsters? I let them feel that the convertible is so windy."

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

Mu Binglan glanced out of the car, and a deflated smile appeared on his face, as if he had guessed what Lin Tian was going to do.

Lin Tian didn't do anything, just took the steering wheel lightly and moved the car sideways, as if giving way to the Ferrari behind.

Zhao Weitao was stunned by Lin Tian's behavior, and Xiaona also blamely said, "He won't find it with conscience, will he give us way?"

Several people are still wondering, Zhao Weitao is still hesitating to go over, but next second, they have no time to consider.

Because it was out of the urban area, the road was not very clean. There was a lot of sand and dust on the side of the road ~ lightnovelpub.net ~ Lin Tianyi drove aside.

Because Ferrari is convertible, just a few seconds, the dust blew into the car. Several people could not catch it, they sucked a few mouthfuls of dust, and their bright clothes and hairstyles were stained with a layer of yellow dust. How wolf howling.

"Lin Tian, ​​you deceive people too much!" Zhao Weitao suffered this crime. Where can't he guess Lin Tian's intentions, he immediately scolded him, regardless of his image or image.

However, just after a mouthful of dust was sucked in, Zhao Weitao could only shut up and quickly raise the roof of the car. After the roof was raised, it was considered to be isolated from dust, but several people and beautiful car interiors were stained with a lot of dust.

"Brother Zhao, they are too bullying." Xiaona and Xiaoya wiped the dust on their mouths and cried to Jiaojiao, but they did not expect how they humiliated others before.

Zhao Weitao didn't say a word, his face was even more ugly, and now he did n’t dare to super, so he could only eat ash in the back.

"Hahaha ..." There was a big laugh in Lin Tianche, and the girls all laughed, but Qiao Xiaoyi, an honest man, smiled helplessly, and seemed to feel that he shouldn't be repaid.

Lin Tian wouldn't bother him either. This guy was so kind that he was almost hit by a car and could help the other side speak kindly. In this state, Lin Tian could only sigh.

People do not offend me, I do not offend. If anyone offends me, I will pay back three times. This is Lin Tian's principle. The sages of Kong did not advocate retaliation with virtue.

Kindness should not be endless tolerance!
