42. window paper

The difference in height of three centimeters is almost negligible, and because of the superior shock absorption performance of the locomotive of Nie Yu and Zhou Lei, this led to the fact that the two did not find this detail in more than 100 times of running in the mountain.

But whether it should be said or not, Xie Fei is indeed a madman.

I can overcome the 'Death Swing' while cornering at the highest speed.

Many readers may not know what the 'death swing' is, so they don't have a good understanding of Xie Fei's almost suicidal way of driving, so let's popularize it here.

PS: These are all needed for the plot of the novel, readers who like locomotives must not imitate, because they are amateurs, there is a deviation from the principle of 'death swing', and please do not spray professionals.

As long as it is a two-wheeler (motorcycle or electric car), there will be a "death swing" phenomenon, but there is a noticeable difference between it and a non-obvious one.

There are generally three inherent modes of instability in motorcycles.

Tipping, shaking, and swinging.

Among them, dumping is easy to understand, the vehicle loses its balance and falls to the ground from an upright state, which is commonly known as 'reversing'.

Shaking and swinging are lateral movements and are the main causes of 'death swing'.

When the front of the motorcycle starts to get out of control, the front wheel produces a rapid oscillation of 8-10 times per second, which we call shaking.

The locomotive as a whole shakes due to the wave motion of the front wheels, which makes the locomotive uncontrollable, which in turn causes a car accident and causes death.

Shake is the movement of the front steering mass around the steering shaft, while swing is the movement of the rear steering mass around the steering shaft, both of which can seriously affect the stability of the locomotive, but the form of the latter is more complex in comparison.

When riding at high speeds of 70 km/h and above, uncontrollable irregular movements from back to front cause the rear wheels to oscillate from side to side 2-3 times per second.

And when this swing breaks through the critical value of equilibrium, the whole locomotive will become uncontrollable, and then it will be thrown out under irregular motion, causing tragedy.

When these two locomotive modes of instability are cross-coupled, the so-called 'death swing' occurs.

There are usually three causes of the 'death swing'.

1. The tail weight of the motorcycle is unbalanced, and the rear of the motorcycle is loaded with too many things.

2. Potholes on the road surface with gravel and fine sand, the speed is too fast.

3. Encounter crosswind interference.

In short, anything that causes the direction of the front wheels to be inconsistent with the direction of travel of the body, and the difference in wheel speed between the front and rear wheels, will lead to a 'death swing'.

Xie Fei, on the other hand, not only installed a cargo box in the back seat of the locomotive, but also stuck the rear wheels on a three-centimeter protrusion, except for the uncontrollable crosswind, has already occupied the minefield where the 'death swing' occurred.

It can be said that death followed him like a shadow, accompanying him throughout the mountain road.

And he used this extreme way, this method of finding death, to turn the corner at a speed of more than 100 kilometers.

I'm afraid that the word 'crazy' doesn't reflect the extent of his madness.

Nie Yu and Zhou Lei looked at the bulge on the mountain road in front of them in a daze, and their hearts became more and more shocked.

No one knows how Xie Fei practiced this technique, nor how he has survived until now.

No one would do such a thing as long as they weren't a patient who had just come out of a psychiatric hospital.

A cigarette burned out, Zhou Lei patted the dust on his buttocks, and smiled faintly.

"Would you risk it?"

Nie Yu smiled and didn't answer, but his eyes gave Zhou Lei an answer.

Obviously, since then, there have been two more madmen on this mountain road.

Those who are still on the Panlongling Mountain Road are not only Zhou Lei and Nie Yu.

Ma Xinnan and Lin Qiaoqiao also stopped in the corner, thinking blankly about Xie Fei's vigorous figure.

Especially Lin Qiaoqiao, he never dreamed that the poor dick who made her a little annoying, and liked to pretend to be 13 when she had nothing to do, actually had such exaggerated driving skills.

"It's still pretty handsome!"

Lin Qiaoqiao muttered to herself, maybe Xie Fei's figure had left an imprint somewhere in his heart.

Lin Qiaoqiao was not the only one who was shocked, but Ma Xinnan was also excited.

She had just come out of the haze of broken love, and her heart was empty and unsettled.

This feeling is very unpleasant, if he has never had a partner, he doesn't feel anything, but when he has been in love once, that kind of daily sharing and companionship has become an indispensable part of life like air and water.

And it just so happened that Xie Fei's appearance seemed to fill the blank part of his heart, and these days, Xie Fei almost occupied his heart.

She had some longing in her heart, and she had some other feelings.

But when she turned her head to look at Lin Qiaoqiao, that kind of calm with a little fiery eyes made her press down these feelings.

She was in a trance for a while, her thoughts were disturbed by the cold wind, and she rubbed her hands very nervously.

"It's not too early, let's go back first."

Lin Qiaoqiao couldn't notice anything, yawned, stepped on the locomotive, and went back to school with Ma Xinnan.

All night, Ma Xinnan was entangled, tossing and turning, and couldn't sleep well.

In her mind, there has always been a figure lingering, that figure riding a dilapidated locomotive, almost pedaling on the locomotive, with incomparably exquisite technology and courage, conquering the detours on the Panlong Ridge.

She was a little difficult to suppress, and even a little unable to extricate herself.

But looking at Lin Qiaoqiao, who was sleeping on her lean, she was extremely difficult, pinched her fingers fiercely, and sighed one after another.

Finally survived six o'clock, she washed hastily after a sleepless night, and rode a motorcycle to Xie Fei's school.

The Yongdong Normal School is not far from the Gongdong Normal School, and the sunshine in the early spring morning is also exceptionally refreshing.

A young and beautiful woman, dressed in simple and clean casual clothes, appeared in front of the school gate.

There are not many beauties in the teacher's college, not to mention that Ma Xinnan has a good figure and good looks, and even the old man who guards the door can't help but look at it twice.

Ma Xinnan was waiting there, waiting for Xie Fei to appear.

After yesterday's battle, Xie Fei's heart was shrouded in a layer of haze, although he won, he always felt that the victory did not come so smoothly, at least there was no hearty feeling.

It wasn't until this morning that Nie Yu told him the reason for Zhou Lei's failure through WeChat, which made this feeling subside slightly.

However, he does not agree with this reason.

In Xie Fei's eyes, Zhou Lei just lost to himself, not his opponent.

I was so confused that I was on the bus back to school, and I saw a playful and lively beauty waving at me from a distance.

"Ma Xinnan, why are you here?!"

Xie Fei was surprised, and his unhappy mood was also dispelled by the beautiful girl in front of him.

Ma Xinnan put her hands behind her back, paddled her feet, and jumped in front of Xie Fei.

"Guess??"
