Quite impressive that these speeds were reached so quickly compared to with the motors. Btw, maybe you could try using a steel lego axle instead of the plastic ones to mitigate the problem of the axle bending. I wonder what speeds could be achieved with that
There's just something about this channel thats so satisfying and deserving of the views. Maybe it's the fact there's no bs, no merch plugs, and that it gets right to the point. Eitherway, love the random experiments, keep it up!
That tire could blow a 12 foot hole in the wall had it broke off the axle. I mean the damage it could create. My friend did this once and the tire came loose at 6000 rpm and it blew out his Wi-Fi. They had to use cellular data for 8 hours!
Do you think intentionally setting the lowest gearing to disconnect after dumping the power in would make it work better? The last one at least seemed to spin longer when that happened unintentionally. Not sure how you would make it disengage, but I wonder how long it could go, and what might make the length of time spinning go up.
youte definitly right, if they disconnected the gearing from the wheel at the end of the pull, that would allow it to spin longer and free-er. Idk that it would improve rpm, but it would give more time to measure the rpm before it dropped off.
@@EllaBananas you're absolutely right it wouldn't spin faster; it only speeds up because of power being put into it, and disconnected it can't put in more power. But spin time and reducing friction tests would be neat to see.
@@Airin258 good point, I forgot that was the only one lubricated, but removing the second shaft by disconnecting it making it spin longer could be interesting. Also, decoupling might make it spin more as less sections experiencing friction, but also less inertia because it is removing weight, but also also it's a minor weight change because the spinning wheels are obviously vastly heavier, but also also also the bearings on the spinning section could be made more focused on low friction while the power train focuses on maximum power and ignores friction because the decoupling . . . basically it could be cool to try?
The speed doesn't really matter that much since it's all about energy in vs energy out. We would be talking about some fraction of how much energy our hands provide into the system which isn't that much. Imagine people using exercise bikes to provide electricity, it hasn't caught on because it's not that effective.
The wheel looks around 7 cm in diameter, meaning if this tiny wheel was on the ground, spinning at 20.000 rpm, it would be traveling at a speed of ~ 264 km/h For reference a regular car tire on the freeway does around ~720 rpm to travel 115 km/h If your car tires were doing 20.000 rpm, you would be traveling at 3.150 km/h, or about 20% faster than an AK47 bullet
What if there was somehow a method to release that wheel like a beyblade? It would become a weapon of mass destruction OR a really really good beyblade
Man I love this. My kid is still 3 years old and we just introduced Lego as next step from Duplo. I can't wait to do stuff like this and teach physics :)
For me, it was from Mega Bloks to LEGO and Mega Bloks, (I think it was them) because they were somewhat compatible. Probably didn't have motors or technic stuff, though.
Yes, obviously. The less mass on the wheel, the less torque needed to spin it, even with the part limitations (as in, the axle twist and the damage from lack of lubrication). So given the same amount of torque applied (same person and gear set), you will see an increase in RPM.
its so cool how you can multiply the speed by getting a bigger wheel to rotate a smaller one, the amount of energy this would be making would be quite impressive
I see someone else has already suggested the steel axle. The ripcord was a great idea! I wonder if the rubber tire induces air resistance. Maybe you can achieve a higher top speed by removing the rubber tire
@Marshall Williams I'd be interested to see the tradeoff if the rubber tire was instead a lead wheel: You'd get an increase in duration of the system, but probably at the cost of RPM given how briefly the energy inputted lasts.
For the string and lube tremendously gives me beyblade vibes, for the ones who doesn’t know (the string and lube) actually works like a string launcher in beyblade, sheesh I wish I could see a beyblade launch with the use of lego. Your videos are amazing!
What I like with your channel, to compare with other "bricks experiment channel" is that you do not want to break record, just to break record, which can lead to bad design choice. You make it for testing, with the correct solutions. Even if I am not interested by breaking record, I am always surprised by the idea you come up to figure out the problem in a smart way, instead of just using 100x motors for instance. It is a nice way to show how a problem can be solve using mechanic.
That's cool! And while it's fun to experiment with LEGO it actually had been interesting to see what's achieveable with metal instead of plastic. It should allow far higher rpm.
If you're attempting the highest RPM I'd suggest using a flywheel with a smaller diameter than the wheel and tyre. The larger the diameter the faster the surface speed, if you like, of the outer diameter of the flywheel, thus resulting in a higher energy requirement. You probably wont see much improvement without using the ripcord method however. All in all, though, a very enjoyable video 👍
Nearly hitting 20,000 rpm with lego, string and lube. Amazing.
That’s physics baby!
and it sounds like F1 loooooool
It actually was a bit more than 20,000 rpm. You can check it by the frequency it produces in the spectroid app (around 337 hz) and multiplying by 60.
anything is possible with enough lube

Using the string is perfect because he gets way more power than the motors have bc hes pulling pretty hard constantly
Also maybe oil, for less friction?

I believe the reason the last one spun longer was because he lubed it. Less friction means less energy loss, therefore the wheel spins longer.
+ less friction without additional shaft

I can hear a LambAudi V10 in there, yeah.
“Wow your car sounds amazing. How’d you do it?” Me personally in question:
A bit of a question: how much electricity could you generate by spinning the wheels by hand?
The speed doesn't really matter that much since it's all about energy in vs energy out. We would be talking about some fraction of how much energy our hands provide into the system which isn't that much. Imagine people using exercise bikes to provide electricity, it hasn't caught on because it's not that effective.
not much, since you would need a super high efficiency dynamo, and also think about the gear ratio and the inertia
Less then a normal hand crank generator.Conservation of energy and all
Very little
how long do you want to spin?
The wheel looks around 7 cm in diameter, meaning if this tiny wheel was on the ground, spinning at 20.000 rpm, it would be traveling at a speed of ~ 264 km/h

with the second half of the experiment, this asks the question; can we spin the small lego wheel even faster?

I see someone else has already suggested the steel axle. The ripcord was a great idea! I wonder if the rubber tire induces air resistance. Maybe you can achieve a higher top speed by removing the rubber tire
The inertia probably helps more than wind resistance hurts tbh
But it will slow down almost instantly, the wheel is there so the slowdown is slower.
It does somewhat, I think in the last video he made where he spun the shit out of a wheel he put it in a vacuum chamber and it picked up iirc 10-15%
@Marshall Williams I'd be interested to see the tradeoff if the rubber tire was instead a lead wheel: You'd get an increase in duration of the system, but probably at the cost of RPM given how briefly the energy inputted lasts.
Using steel parts kinda takes away from using just legos though...

2) speed testing said tracks.
Its so immersive feels like im spinning them myself
i like how the smol gear is like "aight, my people need me!"
