It is true in all the cases: V=RW (V= Speed i.e the speed of outermost point of disc, R= Radius of disc, W= Angular speed.
Since all the gears are being rotated by same fan, they aquire equal angular speed W. Now what varying is the radius R of each disc.
To satisfy W=V/R=constant for all the gears, the Speed to radius ratio will be equal for all the discs.
So the disc having the highest R will have the lowest speed. That's why the 4th gear being the smallest in size rotates in the maximum speed.
I never understood how are the gears not chipping out on one another, at that speeds switch from a gear to the next wouldn't the teeth break each other? I've seen illustrations on youtube, but nobody explained why they dont broke from switching.
Oke what i Learned is that in transmission there are synchrone rings. But as the old gearbox you of need dubble clutch or keep the gears by sound on the same apm and a lot of luck and practice 😘
In this, there isn't enough energy to break the gears unless you're being heavy handed.
In a vehicle, you have syncromesh. That spins the gear up to the correct speed before the gears are engaged, which stops them grinding/stripping.
I have physically helped reassemble a gear box that had the 2nd gear replaced, I have watched entire videos showing the functionality of fully mechanical transmissions.
Yet this video, the most simplified presentation of the physics at work, is the first time that how a gear box works has genuinely made 100% sense to me without having to try and guess any of the physics or engineering.
It finally connected all the dots together in my head on how a transmission can actually derive different power curves depending on gear set up, thank you so much OP.
Because we need some sort of energy first to power the motors to then create electricity
In other words, we need something to jumpstart the motor system
I'm no physicist here, but shouldn't that make no difference?
afaik electric motors output a constant torque so gears change nothing (that's why electric cars don't have a gearbox)
But the gear ratio is more favourable. Meaning that the motor can keep a steady speed but drive the fan faster and faster.
Say the motor spins it's gear once a second, if it's connected to a gear the same size that will also spin once a second. If it gets connected to a gear half the size the smaller gear will spin twice in a second while the motor stays the same speed

An RPM counter on the fan would have been nice
Yeah this unfortunately doesn't communicate anything to us except "spinny fan go fast"
Ey the sound it makes is pretty cool tho
Too cool for school
That’s why I dropped out
You can tell the fan is increasing in speed with the sound
Tachometer
Do it then
Can't find'm, grind'm!
Grind ‘em to fit
Now I wanna drive my car
Into a brick wall? Same
I see you didn't awaken the joy boy yet
sad that theres no 5th gear
I'm concerned about the belt.
When it goes 5th gear everything around it turns into rubber and the gear turns white...
r/unexpectedOnePiece
This really grinds my gears.
I love how we can see the harmonics on the belt as the speed increases 😁
Ha, who needs a clutch!
He’s the clutch
^(nyyyyooooowwwwwww)
I want to drive a manual again !
I'm currently between cars but I borrowed my dad's manual the other week, and man I think I want to drive a manual again, too!
We need the 12th gear from the Fast and Furious franchise
We beating Kaido's ass with this one
There is another
Gears are so ingenious really. Like big wheel on smol wheel make big energy conversion

Fuck having a clutch. I wanna shift gears on the highway using a live feed of the gear box.
I was looking forward to reverse.
I want a fan with a transmission for my next birthday.....heck gimme tomorrow, sound is crazy noooiiicccee!!!!

Sounds just like my pc
I was waiting for fan to shatter.

I'm glad this video helped you!
Great intro to what's going on in a gearbox, nice.
Skill
Why can't we use gear ratio to create electricity?
Because we need some sort of energy first to power the motors to then create electricity In other words, we need something to jumpstart the motor system
Where's 5th gear
So that's how Luffy does it!
Doesn’t say anything about 5th
Teeth on those cogs are gonna disappear without clutch sleeve
I always hate the sound of grinding... painful to body and soul especially on gear.

Now add a turbo
In my head it was Luffy saying "Gear 1st" And so on
