[@magnus0017]

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.

[@justinhenley8700]

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.

[@Airin258]

+ less friction without additional shaft

[@EllaBananas]

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.

[@magnus0017]

@@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.

[@magnus0017]

@@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?

[@flannelflax8078]

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

[@mbcommandnerd]

Oh yes, we can!

[@vtr0104]

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.

A bit of a question: how much electricity could you generate by spinning the wheels by hand?

[@Dantyx1]

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

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

[@marshallwilliams4054]

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

[@steptimusheap8860]

The inertia probably helps more than wind resistance hurts tbh

[@imnotbeluga007]

But it will slow down almost instantly, the wheel is there so the slowdown is slower.

[@wills.5762]

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%

[@johnstrawb3521]

@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.

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.

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 👍
