She again presses on the upper coil, and lowers it down. At this time, the Fred regulator increases the voltage, and the upper coil, despite the resistance, rises up the bar.
– Take your hand off. – Says Fred, and reduces stress. She removes her hand from the reel. The upper coil hangs in the middle of the rod.
– Now get away.
Fred walks over to the dumbbells, and takes one small dumbbell disc. He returns to the table and puts the disk on the top spool. The coil under the weight of the disc drops slightly and hangs slightly lower than before. Fred slowly rotates the regulator, reducing the voltage. The upper disc coil slowly descends. Fred turns the regulator very quickly in the opposite direction.
The top coil with acceleration flies up the rod. Coil, flying up to the stop, stops abruptly. By inertia, the disk flies up and, hitting the ceiling, falls to the floor.
Mother instinctively bounces off the table. Plaster falls from the ceiling. Fred, as if nothing had happened, continues to explain.
– Perhaps the bike will be able to jump. Not so high of course.
Fred picks up the disc and puts it in place.
– Jump then why? – Mom asks stunned, looking at the place on the ceiling where the disk hit.
– This is a side effect. Although it may be useful.
Mother walks to the table and looks at the metal disk.
– What is it?
– Gyro.
– What for?
– In order that the motorcycle could better keep balance. In any extreme case. The gyroscope works like this, look.
Fred picks up the bike wheel. He keeps the wheel between himself and his mother.
– You hold that end of the axis. Put the axis on your index finger and hold it big. This end of the axis I hold. Now raise or lower, each end of its axis.
Raising and lowering the ends of the axle, they tilt the wheel, then one way, then the other.
– The wheel bends down. But! It is worth the wheel unleash.
With his free hand, Fred spins the wheel hard.
– Take your thumb.
Mom gently removes the thumb. The axis remains to lie on his index finger. Fred raises his side of the axis. The end of the axis, lying on the mother’s index finger, rises up. The wheel rises, maintaining the horizontal position of the axis and the vertical position of the wheel itself.
– Nobody holds the other side of the axis, and does not lift it. She rises herself.
Mom is at a loss. She runs her hand over her side of the axle, and over the wheel itself, thinking that this is the focus, and there is a thread that supports this side of the axle. But he cannot find any invisible thread. Fred lowers the wheel to the previous level.
– Hold the axis. – He offers again.
Mom takes on her side of the axis. Fred once again spins the wheel. He removes his fingers from his end of the axis. The wheel is held on one mother’s index finger. Wheel retains upright position. Fred shows his hands.
– See. The wheel does not bend. The wheel steadily holds the given position. The same will be with a motorcycle. With a working gyroscope it will be impossible to drop it.
Mother raises and lowers the rotating wheel with one finger. Fred goes on to explain.
– The wheel will not only hold a vertical position, but also steadily hold at any angle to the horizon.
– Doing any nonsense.
Mother leaves and enters the computer system unit into the room. – This is a computer based on a neural network. We were given out for training. Need to talk to him. Giving him a job. And do not forget about the lessons.
GANG. BASE
A large concrete platform surrounded by the remains of a concrete fence, bushes, trees, and piles of industrial waste. At the site are dilapidated hangars or garages.
Everything is overgrown with shrubs and trees. Trees and bushes grow even on the roof. On the ground, here and there are small mountains of old tires. There are dark spots visible on the concrete all over the site, apparently from engine oil. Probably here once upon a time, there was a yard of a transport company. Behind the skeleton of the rusty gate and behind the trees growing outside the gate, there are frequent and diverse sounds of passing cars. There is a busy motorway.
A group of motorcyclists are having fun at the site. One train in riding on one rear wheel, makes “willy”. Another motorcyclist burns rubber (he steals and slips his rear wheel while holding the front wheel brake). Smoke comes from the rear wheel. Black traces remain on the concrete. Smoke with the smell of burning rubber spreads throughout the base.
Another motorcyclist engages in slalom. He quickly goes around the old tires laid out at some distance from each other.
The rider who trained to ride on the same rear wheel starts making stops. Another one drives up to him (the one who “burned” the tires), and they are competing who will pass more on one front wheel.
At the improvised “table” consisting of a stack of old cracked concrete slabs, there is a guy, this is Gray. His name is Sergey, but almost no one calls him by name. He is in a leather jacket and leather trousers. In the eyes of fashionable, dark glasses. His open helmet lies on a concrete slab. With fingers of his left hand, he sifts through thief beads. Gray has long dreamed of becoming a cool mafia. But so far, he could only become a mediator in the resale of stolen goods.
From behind the trees and bushes, from the side of the road, through the rusty skeleton of the gate, a motorcyclist enters the site, breaking the glass of the car. This is a Mountain. His name is Igor. He is the biggest in this company. Apparently its size, in combination with the name and served as the origin of the nickname. Mountain is not the biggest, but not the smallest motorcycle. Nevertheless, he looks almost like a moped on his motorcycle. The mountain stops the motorcycle near the “table” and, putting it on a stand, goes to the plates. The rest stop their classes, and also begin to move closer to the “table”.
Looking around all those gathered, Gray refers to the Mountain.
– Well, how much did you get today?
Mountain takes out the loot, and puts it on the “table”. Speaks in a bass and very loud.
– Yes, so small change in the main.
Through the skeleton of the gate, another motorcyclist enters the site, this is Dan. When Dan is not on a motorcycle, he almost always imitates a shadow fight. He makes demonstrative “blows” with his foot, arm, head, chest and other vital organs of an imaginary opponent. He constantly punches his right hand in the palm of his left, and vice versa. Sometimes he stuffs the edge of his hand on the railing, or knuckles on the wall. Dan considers himself an expert on karate and other martial arts. He begins to take booty out of his pockets – watches, jewelry, expensive-looking glasses, a cell phone.
– I have nothing standing either.
Gray appreciates Dan’s booty.
Not far from the table is Tikhon. He is wearing baggy clothes. Tikhon thinks that it is better to hide the light fullness. He has the oldest single-cylinder motorcycle, the smallest working volume, the smallest power and with drum brakes.
Dimon comes up to the table. He constantly chews the cud. He looks in the mirror with great regularity and brushes his hair. Dimon pulls out a comb, and plays it like a knife, rotating between his fingers. He wears an expensive brand motorcycle jacket and the same pants. On foot moto boots. He constantly rubs his shoes, and his jacket from dust. Also constantly rubs its most expensive, new and powerful, in this company, motorcycle. He turns to Tikhon.
– What about you? Hoping to find money just lying on the road?
Dan sneers at looking at Tikhon. – Yes, he is honest! He honestly wants to earn a new motorcycle.
