Bicycle

00:00:02

Lord God, I studied physics for 6 years,

00:00:06

only now I realized that physics is the science

00:00:09

of optical illusion, how do

00:00:12

you really look at yachts against the wind,

00:00:14

heavy planes and helicopters are sailing, but

00:00:17

two-wheeled motorcycles and bicycles don’t

00:00:20

fall, or almost don’t fall,

00:00:29

I wonder what forces keep an

00:00:32

absolutely unstable structure moving

00:00:35

in immobility,

00:00:36

first, let's take a bicycle wheel and

00:00:39

try to put it no matter how hard we

00:00:43

try, the wheel will fall just

00:00:45

like a stationary bicycle falls, and

00:00:48

what will happen if the wheel is rolled in this

00:00:51

case, it will remain in a vertical

00:00:53

position until its speed

00:00:56

decreases to a certain limit

00:01:00

rolling the wheel does not fall due to the

00:01:03

gyroscopic effect during

00:01:06

movement, the wheel seems to resist

00:01:09

attempts to change its position,

00:01:11

it is this property that prevents the

00:01:14

rotating top from falling and does not allow the wind to

00:01:17

overturn a toy flying saucer,

00:01:20

which gives rotation during a throw, the

00:01:24

effect of the

00:01:26

gyroscopic effect on the example of a

00:01:29

Latin American top is especially interesting. and with a

00:01:32

successful launch, the top can maintain a

00:01:35

horizontal position,

00:01:36

hanging on the side of the suspension, but the forces capable of

00:01:40

holding the top in a horizontal

00:01:42

position are not enough to maintain the

00:01:45

balance of the cyclist at low

00:01:47

speed. The stability of the bicycle is also

00:01:49

affected by its design; the bicycle itself

00:01:53

steers in the direction in which

00:01:57

its front fork is trying to fall it is made in such a way

00:02:00

that it itself, without unnecessary help,

00:02:02

turns towards the tilt of the

00:02:04

bicycle, this is what allows you to ride a

00:02:07

bicycle without holding the handlebars at all,

00:02:10

if you replace the bicycle fork

00:02:13

with such a

00:02:14

curved one, you will get a bicycle

00:02:17

that will be much more difficult to control;

00:02:19

in order to maintain balance on such a

00:02:21

bicycle you will have to be very actively

00:02:23

work with the steering wheel and you can completely forget about riding without hands

00:02:26

at the slightest tilt, its

00:02:28

front wheel turns in the

00:02:30

opposite direction from the turn

00:02:32

and every time the bike will try to

00:02:35

jump out of the entrance, so what about the

00:02:38

mechanics of controlling two-wheeled vehicles,

00:02:40

we seem to have figured it out,

00:02:42

the bike remains stable

00:02:44

thanks to the gyroscopic effect and

00:02:46

the design of the fork,

00:02:47

but we must not forget that without a person

00:02:50

the bike will not go far on its own,

00:02:53

but how a person feels how much to

00:02:55

tilt the bike is a question for

00:02:58
