TLDR:
- Pulley edge speed: *281km/h = 175mi/h*
- Pulley edge acceleration: *507000m/s^2 = 51682g*
- Estimated centrifugal force on whole pulley: gravitational force of 30kg on earth
I assume this is LEGO part 4185. It has a diameter of 2.4cm and therefore a radius of 0.012m. The velocity at the edge of the wheel at 62109RPM = 1035 rev/s is v = π·2.4cm·1035 rev/s = 78m/s = *281km/h = 175mi/h*. This means the centrifugal acceleration at the edge is a = v^2/r = 507000m/s^2 = *51682g*. Which is an *INSANE 50000 times the acceleration on earth*.
Considering that the acceleration is lower closer to the axle and most of the wheel mass is close to the edge, I estimate about 30000g of effective centrifugal acceleration on the whole wheel. With a wheel mass of 0.97grams ≈ 1gram the centrifugal force corresponds to a gravitational force on a mass of about *30kg*.
Thank you very much for that 😀
The comment I was looking for👍🏻😂
Does this mean that this could potentially be a missed launcher
I respect your effort and mostly the fact that there are heroes like you.
Holy... Lost for words.
I assume the pulley is sliding back and forth like that because it's stretching under the centrifugal force and becoming a loose fit on the shaft. I'm amazed you didn't melt the final bearings.
Hey yes! I couldn’t believe this at first as these pieces are a seriously tight fit and have little give on them😀
@@GazRsExtremeBrickMachines I think you should ask Gav or Destin if you can borrow one of their ridiculously high-speed cameras...
If you are interested in the forces, check out the pinned comment. That person calculated it
I wonder how this would perform if you lubricated things..
@@BazilRat awesome idea, but I would assume Seal got it right. The forces can become quite high and the piece is likely to expand by tenths of millimeters at least
I really miss when CZcams was just full of random interesting videos like this. No production level bs or thumbnails stuffed with garbage to grab attention. Just something cool to watch
You don’t think “random interesting videos” aren’t made to grab your attention? Clickbaiting is inevitable on a site like CZcams (or on the internet in general), and why would there be something inherently bad with high production value videos?
@@Erik20766 they're made to showcase something cool, not to grab attention and produce revenue, like most of the content that is currently being made and pushed on CZcams. It's high production quality but low content quality
Cheers Michael that means a lot😀 I love watching CZcams videos(I’m that one at 1am… like many)
The thing that gets me is how many string there videos out to over the 8 minute mark so they can add the adverts in the middle! The silly thing is by doing this their viewer retention lowers and CZcams is less likely to recommend.
Man I seriously am feeling like one day you will make that a projectile launcher, and it scares me. But Great job!
Haha I do have plans for this! And thank you so much 😀
What a great idea
It's the same tech that goes into Nerf Flywheel blasters and Baseball Machines
I feel like a small mishap could have turned it into a projectile launcher
given enough leverage you can move the earth as someone smarter than me once said. I bet we are going to see amazing things given enoughs motor
Nobody:
Honda Civics at 3am:
😂
Check my next video! Vtec….lol
wow never heard that one before 😐
Why not just say “sounds like Honda Civics at 3am”? Why the stupid meme of “Nobody:”? It doesn’t even make any god damn sense, and suffers from not even an ounce of originality.
Just having a “what the hell has internet culture become” moment, everybody. You would too if you’ve been using it since the mid 90s.
@@GeddyRC yeah, zoomers have no originality, just using this stupid macros
In fact the speed at the rim is the parameter.
In 1988 I had (at TNO/ECN, Netherlands) a vacuum vessel with a techical composite flywheel in it. An early KERS system.
Mass was 4.4 kg, diameter 0,3 m
First test went directly to 600 Hz = 36000 rpm. Rimspeed was 565 m/s or 2035 km/h
Mach number cannot be calculated, we were working at a few milibars.
Fracture speed was estimated 1000 Hz, or 60000 rpm, I never tested that.
Expansion of that wheel was covered by a flexible hub-wheel connection.
It could accelerate a 1000 kg car to 180 km/h.
Nobody would believe this, but every word is true. Groeten from NL.
Thank you for that read very interesting! and I do agree about the rim speed!
Well that's terrifying imagine a real circular saw blade on that beast it'd probably spin the teeth right off the blade lol awesome man keep up the good work
Haha cheers Nathan I almost put the blade on but the batteries started running low! And it took awhile to charge 60 😀
@@GazRsExtremeBrickMachines How much do you estimate the torque is? Do you think it'll instantly stop when you touch it?
Hey! Torque was very low! Hard to say as I didn’t try but I imagine with gloves on you could stop it instantly with ease probably just by touching it let alone grabbing it
I can’t tell you how much fun these are to watch! I just love the crazy things people can do with just lego! Keep it up man!!!
Hey cheers for that Easton, I was hoping to do a few more but I’ve had that man flu again lol. I need to get on with it 😀
Talk about speed! I never thought legos could go that fast! Keep up the awesome work!
Hey Jared cheers, it surprised me! I think this is near it’s limit now for me at least 😀
1 year later: flying to the space with 100% Lego Technic))
😂
I would go for 300000 revolutions per second and hopefully watch space and time collapse 😅
Mybye a helium full ballon in lego is possible
Designed in Kerbal Spce Progran, then built in Lego.
Amazing how that pulley was pulled loose from its shaft, I did not expect that! Then again at those RPMs the forces on that pulley are no joke...
30kg of force on that wheel, which is 30000 Gs
just think yall. 1000RPS the wheels is making 1000 revolutions in the time it takes a person to snap. The average blink is 300 milliseconds so .3 seconds. So in 1 blink the wheel rotates over 300 times. It sounds so mundane at a glance but in reality that's freaking insane. The only thing that can compare in craziness is how fast space craft move. (14,000 mph or 4 MILES a second).
Cheers for that! When you think about it like that it really is crazy to think!
How some race cars last for thousands of miles revving past 10k is mind blowing!
I really love those LEGO experiments
Hey thanks for that feedback there’s a few more to come 😀
@@GazRsExtremeBrickMachines I'm excited 👍
Thank you for accepting my suggestion and showing us how you build something. :D
Haha super quick build! And thank you 😀
Geez! I was just waiting for it to ‘explode’ any moment! Absolutely insane 🤯 what do you think the max rpm could be with the right gearing? Great video!👍👌🤘
Cheers Nick I was kind of hoping one would explode as it would make a good thumbnail pic lol.
For more rpm I think the frame needs to be more rigid, literally no give in it. Some more power would help too but I think it’s near the limit for me.😀
I was expecting to see MUCH MORE vibration. I am surprised to see how balanced all the parts are .
There was a little at low rpm but at peak it was smooth which surprised me too!
Congrats for making consistency of drill sound!
I'm not sure what the L motors are like, but I know that the XL have a big gear reduction built in, so spinning them faster is wasteful vs just using a M motor. Someone will probably tell me there's no gearing inside the L, in which case, just add more motors
Hi the XL and L spin at nearly the same speed! The L is 299 and XL is 305 in powered up! The power functions XL has really short gearing though😀
I'm back to YT after a long time and BOY has your channel grown. Its huge now! Your machines are progressively getting better (and scarier😅)
Hey hey sorry for the late replay! I can’t believe how it keeps growing! And thanks for all your comments cheers 😀
i love this videos ! nice work :)
Hey there I’m glad you like it! Cheers 😀
Lego... You are never to old for this ;)
Wow these are fun but can’t wait to get to see new cool vehicles
Hey there they’ll be coming I’ve just got a few things to get out the way first 😀
Holy smokes! You got it to spin to 62,000 rpms! That is incredible! You must have found a good lubricant. I'm curious to know what you used for lube?
Hi Josiah cheers! I used a few types. First wd40 but the last axles were still melting a bit! Also Olive oil again but it’s thick but it does a great job at protecting! Then I tried some silicone oil which seemed to work the best😀
@@GazRsExtremeBrickMachines Wicked cool! I had no idea that olive oil would work better than WD-40. Great to know the silicone oil worked the best. Keep up the great work!
Thanks again, the WD worked great on the other gears as it was thin but the last axle needed abit more protection 😀
@@JazzbLu WD-40 is not a lubricant
@@benespee5321 Ok and?
how don't the axles melt and start smoking? and how does it spin with so much friction? if you have the motors the other way the last gear will probably have no seen movement! super cool! keep it up! also when you get that fast you probably need to have a metal wheel as the plastic will blow up! :O
I used a lot of lubricating oil and I had to spray it every run this time!
I did keep out the firing line aswell lol 😀
@@GazRsExtremeBrickMachines I hope that was genuine Lego oil!
😂 I like it
The balanced forces on the stages also helps to keep the forces on the bearings manageable A very clever design for combining the torque of the many motors needed to overcome the friction. The same speed can be achieved in a single motor with precision metal gears so the effort required here is a sign of the size of the task undertaken.
@@GazRsExtremeBrickMachines try use silicone instead
It's people like this that will put legos on Mars before man gets there.
Bro you're crazy😂 I recommend mounting a v8 or v12 to that if it fits or a Lego engine at all and speed it up until the heads fly >:D hope you have a great weekend and stay safe and fit ✌🏻
Hey dude thank you so much and you too!
I only have one vintage Lego engine but that’s a great idea lol. It was from the original red Technic car! I will try that out but worried about it seizing up 😂
Man you are AWESOME keep up the good work
Cheers Cody, I really appreciate that! I have a new rpm test video out tomorrow too :)
My ears would yeet themselves backwards when you cranked it up and the high pitched whine kicked in. Scary awesome.
Sounds like a subway train starting up. Mildly terrifying. 😄
Try adding some lubricant on the axles, and even more stability! Great vid as ever.
Hey I used lots of lubricating oil! Half a can! I had to keep applying it each run I should of showed this. I think part of the problem was the model being on wood and vibrating, it needed rubber legs. And thank you very much 😀
@@GazRsExtremeBrickMachines I wonder how graphite would compare.
@@GazRsExtremeBrickMachines I think Silicon grease would work better tho
i once had a lego windmill (which ran 24/7!) and its axle got some serious wear! there was lego powder around it till i put some oil on it maybe you should oil this (it may reach 200,000 rpm)!
Hey that’s a good idea I wish there was a Lego way of converting the power into a hub!
I did use lots 😀
Some might say this is a revolutionary test
😂 I like it!
Don't know why but i totally love this stuff 😂
I want to see this machine used to pop some CDs and DVDs. A few Blu-ray discs would be nice to see as well.
Can't wait for saw 4
Imagine the police turning up because of a neighbours noise complaint, and you had to explain that you were just playing with your Lego,... 🤣🤣🤣🤙🏻
😂😂😀
This is crazy idea,,, with this I think one can attain the rocket speeds
now imagine that thing launching HotWheels!
R.I.P. Wheel
1,000 full rotations every second. Incredible
So satisfying.
Hey thank you for the comment 😀
22 motors wow. Also pog video
And thank you as always 😀
You make lego sound like the angriest wasp in the world
That is absolutely insane... I'm having a hard time believing the numbers because it just seems to ridiculous. I love it!
Hey thanks for the comment! When I think about it myself it does seem hard to believe as 1000 spins a second is hard to comprehend😀
Wow is so fast, big gg! 😉
Hey cheers Ombre 😀
If that thing breaks and goes flying at 60000rpm, you'd have a new window
1:40 my laptop when I play minecraft
So... your three reason extra motors are always out of stock?!
Great vid bro, very impressive stuff!
Lol How that made me laugh! And thank you very much appreciate it😀
That’s a lot of money just in those motors!
Nice video!
Hey Demetri thankyou! Yes those L motors are not cheap but I do buy the big sets second hand(42100) and it doesn’t work out too bad if you sell parts back 😀
under $36 each.
That moment when the pulley stop vibrating, because it know it is getting dangerous and need to hold tight
I feel the need..... The need for speed! Very well done.
Thank you very much 😀 Top Gun? I love that film!
Soon this guy will construct a lego 280kph high speed rail train with this
Next video: making centrifugal refinery for uranium ore.
If I ever see a headline "Man Killed by Lego Projectile", I will know why.
😂
Thats aggressive😯👍
If you want even more rpm, try brushless motors with lipos, you wont be disappointed 😉 540 size brushless motors would fit lego and can run on about 3s lipo
That would be mad! For now I will stick to the challenge of Lego but I will definitely try other things in the future! And thank you too 😀
Next: from last episode the motors give all it got so this time with 100 motors and see if it can reach 1 million rpm
Haha can you imagine charging all those batteries! I used 10 hubs on this one(60 batteries)
@@GazRsExtremeBrickMachines ebay: I got u bro
😂 I’m on it too much
My brain refuses to understand that this gear in the middle spun FUCKING MORE THAT A THOUSAND TIMES IN A SECOND
I kept thinking the same! Hard to comprehend.
That's nuts, I can't believe that plastic doesn't start to weld itself together
Nice challenge!!
Hey there thanks you 😀
That's pretty darn fast for Legos, but if you really want to see (sort of) something that _really_ spins, just shoot an AR 15. The rifling spins the bullet up to around 350,000 RPM, now _that's_ fast lol.
Dam that’s crazy! I never knew that cheers!
The key is Balance the wheel and shaft and good bearings in the high rpm areas :) in the video hear buzzing and whinning on 30%-40% load it causes the shaft isnt center ,the wheel isnt balanced properly and the hole is much bigger than shaft.
THAT
IS
AMAZING!!!
Thank you!!!!!!! 😀😀
Someone is gonna make an all lego life-size lego car that can go 200+mph I just know it.
3:20 old 1990 chevy manual pickup truck trying to start up for the first time in winter:
Завораживает, мне понравилось смотреть! Спасибо! :)
How this is possible without bearings escapes me
60k rpm is insanly faster than it looks or sounds, i am truly amazed by how the legos pieces didnt break with the force, and by the last gear not melting
Cheers Miguel! I did use a lot of lubricating oil near the end! Hard to comprehend just how fast 1000 times a second is, even more amazing to think that car turbos spin a lot faster!
@@GazRsExtremeBrickMachines true, but turbos arent made of legos, plastic gears and small electric motors...to my eyes, what you did there is more impressive than a car turbo 😂
How’s the ware on axles because this machine has so much power!
Hey Chris I used a lot of lubricating oil each run but the 60k runs destroyed them two 5 axles very quickly! I should have showed this!
I’m attempting this wheel spinning off now! Cheers 😀
@@GazRsExtremeBrickMachines Awsome
Love it throws the tire off.
I can't believe how balanced those gears are made wow I'm getting a set for my girls
At 1000 revolutions per second, I heard 1000 Hz.
I was waiting for the extreme centrifugal force to explode the wheel at that hi of rpm 👍🏿
Very nice! yesterday, i missed at 13.000 rpm
Hey thank you very much 😀
could you maybe stack another one of these setups on the current one to double the amount of engines with a minimal amount of volume increase?
My two L motors are crying
Nice!
"and next week, watch as I create a fully-functioning nuclear reactor out of lego."
You have a third dimension. Use it. MORE MOTORS!
Nice job man i watched another guy do a similar experiment but he only got to 7,000 rpm and the axles started melting into the frame did you use any lubricant or just lego itself??
Hey there I used a lot of lubricant, also it helped powering both sides as it was more stable! And thank you 😀
you should create a car using these mechanics
Dude I can smell the plastic burning through the phone.🤣
Lol Joshua😂
Cool vid
Thank you 😀
This is why some tires say "not for higway use" .. If wheel goes to fast you gon break the internet.
Rimspeed is the parameter for energy storage. The stress/mass ratio is governing paramter. So composites come in sight, instead of lead.
I demonstrated high enegery values per kg with a composite flywheel, (36000 rpm at 0,3 m diameter) but the bearings at very high revolutions in near vacuum(!) , the motor/generator and the safety casing were a limiting factor.
Beside that gyroscopic effects are a point in vehicles.
It becomes too complex, so modern batteries have won the race.
Hi there thanks for that! Btw I’m not sure if you’ve seen my tracks spinning fast video?
Would you know how much weight I could lift by using the centrifugal spinning force or what calculation I would need?
Any help is much appreciated 😀
1:10 the sound it gave off turbo honda vibes
I imagine you're now running into an issue where the motors might be holding ya back. Given that there are multiple if any one of them is out of sync its going to work against the rest. Might be interesting to grab a single motor equivalent and hook it up
Hey there. The problem with a single motor or input would be the axles can’t take the torque and just twist and snap. So with Lego you need several input axles to spread the load unfortunately.
I will try one more time to see if we can best 100,000😀
@@GazRsExtremeBrickMachines Three solutions that come to mind just off the top of my head. I know nothing about Lego so feel free to ignore me. You've probably already thought of these but on the off chance I can inspire a solution: First is possibly finding a way to reinforce the initial intake axle. Not familiar with using Lego at all but maybe use multiple of the gears to bind a whole bunch of axles (rod pieces?) together, the gears acting like the actual axle and the axles like rebar. Another is distributing that force out in an inverse gearing until the material can appropriately compensate for the forces generated. Basically you'd create another transmission before even getting to this thing you created here. Third is running those motors where they aren't competing with each other, thinking something akin to belt drives but I understand that might create too much slip and might not even be possible in this medium.
Look forward to the next attempt, truly a fascinating thing and amazing how far you can push these little plastic bricks! I'm not sure how much luck you'll have with so many motors working against each other but fingers crossed!
No, they’re all forced to be “in sync” by the gearing and it’s okay if they don’t all produce the same torque; it’s additive.
It would be interesting if you would try to put some oil ore something like that on there to reduce friction even more
Hi I did I should have put it on the video! I did add it in the description😀 I used lots
Richtig interessantes Projekt 👍
Wow!
Wow! I didn't know this man was running a whole factory!
Haha hey Nick!
Make a lathe.
My brain trying to comprehend something spinning 1,000 times a second when I can barely spin around a baseball bat 10 times in 30 seconds🤔🤣
😂 I will look into doing a lathe thank you.
Please, please, please, be careful with your finger on that
I was this time 😀
If it disappears it means it has time traveled
Would love to see a thermal cam view.
Hmm great idea, stay tuned thanks 😀
You should do a Lego miter box
MORE MOTORS!!!!! 🥵🥵🥵🥵
And Nuclear Fusion was achieved…
DREMEL TOOL as motor 😁
Please make a wheel launcher. Imagine launching that gear at 60000 RPM
Great idea I’m playing about with this idea now 😀
Now make it into an op table saw by changing the wheel with a lightweight blade with the right fitting
I have done already but I will be making one with a metal blade soon 😀
