Spinning a Lego wheel Over 100,000 RPM! 4K

  • Published on Feb 20, 2022 veröffentlicht
  • Unthinkable speeds using 100% Lego Technic! Mesmerising Sounds!
    In this Lego Technic RPM Test I’m using 27 Powered Up L Motors powered by 10 control+ Smart Hubs.
    I believe this is the fastest spinning Lego wheel, axle there’s been on Clip-Share!
    100,000 RPM equals around 1,666 Revolutions a second which is hard to comprehend.
    There’s all a vintage wheel rim which cannot handle the centrifugal force and explodes!
    Thank you for Watching, Subscribing and Liking! You people are great :)

    This really is testament to how amazingly designed Lego is. I wonder but I can't help but think that you were likely getting quite close to the physical limits of the material in those last few tests

      @Sina Ozbudun kids playing with, stepping on, etc, puts more stress on these parts than spinning them fast. The design requirement isn’t centripetal/centrifugal force. It’s compression and shear. Given that kids still break them, it’s certainly not overbuilt.

    Assuming you have a disk with a diameter of 10 cm, you would have to reach about 65000 RPM to break the speed of sound, that would be incredibly awesome....
    Amazing video by the way, as always.

      @ProLansPl The problem is, spinning black holes are essentially pulling space itself at relativistic speeds, so it's more comparable to two people driving away from each other at half the speed of light. If one of them were to turn around, it would look like the other one is traveling away at light speed, but realistically only that person's frame of reference is traveling away at light speed. Since black holes are dragging space itself and therefore the frame of reference, the objects inside an ecretion disc aren't actually traveling near light speed, they just appear as though they are to an outside observer. That's how a lot of people conceptualize FTL travel, warping space itself instead of traveling through it.
      The issue with moving things at the speed of light *through* space isn't a size problem, it's an energy problem. If we built a 300,000km pole on a planet that rotates one time every second, the pole would rip itself apart because the energy needed to keep the pole together if part of it was traveling at light speed would be infinite.

    • ProLansPl

      @Dr Gamma D that's all cool, but the prospect of seeing relativistic effects in the macroscopic world and in real time is more than tempting. I mean, the guy used relatively simple materials and tech. assuming it's taken onto the next level (it would be "only" beefing it up couple thousand times), the particle on the edge of a disk would hit (okay, okay: be near to) speed of light. these are effects experienced by particles encircling the black holes - spinning so fast they can "see the back of their own heads". correct?

  • gibbled0
    gibbled0 Year ago +676

    At these speeds, balance is quite important. I would recommend using a silver/black sharpie instead of reflective tape to get rpm measurements. Also, that tachometer you are using will give inaccurate results if it's not held steady. Try attaching it to a stable platform instead of holding it in your hand.

  • WarChallenger

    Well the next logical step is to rig a system to release a propeller at max speed. Imagine the height it could achieve.

      @Tim Sawatzky Makes sense. I'm more familiar with cars than aircraft. Thank you for letting me know my weird idea ain't all that weird after all!

    • Tim Sawatzky
      Tim Sawatzky 16 days ago +1

      @WarChallenger you've actually described a real world constant speed propeller. This is what you'll find on all turbine powered prop aircraft, like a Dash 8 or King Air. The blades increase their angle with increased torque through engine power to bite more air. The rpm or the prop remains more or less the same, but the angle of the prop blades change depending on the torque output of the engine.

    • AadU
      AadU Year ago +2

      There is a reason the Thunderscreech took lots of time to design. Propellors don't work at high speeds, even with the variable pitch.
      Such a propellor is only possible in the Fast and Furious world, where nearly every law in physics is broken.

    • Priyabrata Sadhukhan
      Priyabrata Sadhukhan Year ago +1

      His motor is too weak to drive a propeller even at 1/10th of the speed you are recommending. For your reference, most hobby drone props rotate at 20k to 30k rpm at full throttle and consume a few hundred watts. Now think how much it will take to rotate at 100K. Its not proportional by the way, It would take a few thousand Watts. physics becomes weird at that speed.

    The fact that it can go this fast, with what appears to be only official Lego pieces(unless you are using BuzzWiz motors) is incredible. If you want to go even further, you could mirror this and connect it to the other side. However, if you want to achieve speeds higher than this, you might need heat treated axles or metal axles.

    • OsmeOxys
      OsmeOxys Year ago +7

      @joachim the boss The poor motors are seriously struggling for enough torque according to GazR, and the theoretical versus real RPM backs that up. Meanwhile everything else is struggling with too much torque lol. Damn cool just how ridiculously over the top the guy has gotten these things to perform.

    • joachim the boss
      joachim the boss Year ago +1

      mirroring would result in 2x the torque not 2x the speed. unless the motor torque is insufficient for achieving the required torque that the system needs to achieve the speed limit in which case mirroring would result in sufficient torque for every motor to spin at their maximum speed

    I absolutely LOVE gear ratio and high rpm videos, especially with lego, just seeing how far the limits can be pushed. I wish there was a world record leaderboard for this kind of thing, "fastest rpm with lego" to promote competition and push the limit as high as possible.

    That sounded like a dentist's drill towards the end. Not surprising, given those tend to spin at ludicrous speeds as well (seeming speeds in the 180K RPM range). While each mechanism does have a distinct sound due to its own setup, it does seem like speed overrides that past a point. Interesting.

    I feel like having it built as a tower, all the wheels are pressing with their entire weight on the parts bellow them, resulting in high friction.
    Can you turn it horizontal?
    And use a high speed grease.

    • GazR's Extreme Brick Machines!
      GazR's Extreme Brick Machines!  Year ago +48

      Hi, Everything free spun so smoothly and when you spun it fast the device actually lifts up due to the forces at play which takes any load off those bottom cogs.
      I totally understand where you’re coming from though but in person you would see :) you actually have to pin it down like I did with those two outer beams to stop it floating up! It’s weird lol
      I’ve done other tests with these devices sideways and the big problems is there’s more load on the axles going downwards into the beens which then creates serious friction welding! Check my other rpm test to see.
      I used silicone lub, also WD40 and 5w 30 engine oil which gave the best protection 😀

  •  Ferroequinologist of Colorado

    One thought I had about this system was to possibly doa test to calculate how much torque is produced at the output. The only problem o can see is either overloading the motors or irreversibly damaging the gearing mechanism.

    All you would need is to add something with a radius of 4cm and the tips would be above Mach 1. For comparison the fan of a turbofan jet engine spins around 2000-3000rpm, even the turbopumps on the RL-10 rocket engine only spin at 40000rpm (it is expander cycle though so low mass flow means low speed pumps). Nonetheless. This is fast

  • Brenden Roughley

    Sulfur hexafluoride at room temp has a very low speed of sound, is somewhat obtainable and safe-ish, plus because it is heavy you could fill a tub and do final high speed test to get an insane mach number out of lego. It is a very potent GHG though, like super mega Godzilla CO2 so use sparingly after maxing in air ❤ chilling below room temp also reduces speed you need/will give even higher mach number. Room temp to -40c with air you only need 88% speed for mach1, Ideally you would run a vacuum to remove ""all"" the air and then just squirt in a tiny amount of SF6 in an industrial cool room to have min drag of gas and be able to get the highest mach number to make the ultimate lego mach record. HYPERSONIC LEGO MACHINE!

      an amusing technicality to be sure, but i think it can be assumed that by "breaking the speed of sound" they mean the speed of sound _through air under standard atmospheric conditions_.

      Yeah build something and then dismantle on film and everyone thinks You're even more of a genius builder! I need a beer, have been hooning and it's errrr, hard work!
      I saw a rev machine that Colin Furze did, that launches a tyre. I bet if you did they with Lego it would fire it miles 👍🍺🇬🇧

      I never thought of that Carl, I rebuilt it again lol.
      And cheers appreciate it! My only wish was the sound of the big white rim would have come across in the video! It was deafening! But it came across as the quietest!😀🍺

    I've heard that there are small-size stars spinning about 1000 RPM, That's a miracle!

    I'm confused. In the first layer, all the gears seem to be enmeshed with all their neighbors. Wouldn't this lock the system up and preclude any movement? What have I missed?

    The fastest RPM is 600 million and that is just mind blowing. 2013, scientists at the University of St. Andrews made headlines by propelling a tiny sphere to a record-breaking 600 million rpm (revolutions per minute). This new object out-spins that by a factor of 100.Sep 10, 2018

    Hard to think how much speed can you achieve only with LEGO

  • Man Overboard
    Man Overboard Year ago +1

    It seems fast but it is going to be incredibly hard to break the sound barrier as the fastest object in that 100,000 rpm scenario is only moving 25 m/s. You'll need to increase the radius significantly, which requires much more power

      Hey I really appreciate it! I may have to get creative but like you say that does seem possible if it’s light :)

    • GazR's Extreme Brick Machines!
      GazR's Extreme Brick Machines!  Year ago +1

      Hey nice thinking! I’m intrigued to see how that would work! I could add tiny tiny little weights on which could keep it stable.
      I was thinking of cutting the inside of a paper disk out so you mostly just have a rim other than 4 connection points. But it may create more drag that way.

    • Man Overboard
      Man Overboard Year ago +2

      @GazR's Extreme Brick Machines! Another idea is to use a fishing line to reduce inertia but it may bend too much because of air resistance to get consistent speed measurements (unless there is a way to put it inside a vacuum chamber)

    • Man Overboard
      Man Overboard Year ago +2

      @GazR's Extreme Brick Machines! Well, a 17cm paper disc with 40 000 rpm sounds doable I guess (which is slightly above the speed of sound), anyhow, good luck with that project :)

    • GazR's Extreme Brick Machines!
      GazR's Extreme Brick Machines!  Year ago +1

      Hi it will be very tough! The paper spun at 110 m/s btw and the saw blade 98 m/s or 220 mph.
      I have got a few ideas though! :)

  • Филипп Лыков

    1:09 The nearest and the farthest gears do nothing as they are not connected "upstream".
    6:19 Reaching the speed of sound at 102,465 rpm = 1700 rps it will take a disk with circumference of about 20 cm i.e. diameter of 6 cm. You might have already achieved that.

    • Филипп Лыков

      @Gnash R You are right. I just watched slow motion of the assembly process and noticed there were two axis stubs visible atop of the traverse bar.

    • Gnash R

      At 1:09, dont the nearest and furthest gears help to distribute the torque as they are connected to the system with tiny gears?

    The Ultimate Beyblade launcher! LOL 😁😂 All jokes aside, I am _seriously_ impressed with these Lego gears! The fact they didn't just immediately strip each other of their teeth, or just fracture right off the axles is astonishing!! Way to go Lego quality control 👍

    Absolutely amazing, especially for a plastic Lego set.

  • Νίκος Ιστοσελίδα

    This is crazy! And incredible. Wouldn't you be able to reach even higher RpM if you didn't have the "showcase gear" due to lower energy losses?

    • The_Great_Magicman
      The_Great_Magicman Year ago

      the showcase gear is 1:1, it uses less than one 625th of the systems torque, youd get something like 100 extra rpm by removing it
      the reason the top cog made such a difference is due to the 1:625 gearing

    Would be cool to see a soft object (maybe like some play dough) get spun super fast just to witness the sheer destruction. Also what would happen if you spun some random objects that fast (like a lego wheel or maybe the saw that you used)
    Also for the breaking the sound barrier thing maybe you should try a stick instead of a disk that way you might actually make a sonic boom (maybe, don't rlly know if it would work but it's worth a shot). A stick is lighter, and if it's the same lenght as the disk is wide they would both reach the same speed. Though maybe the stick might create extra drag, which might negate the whole it being lighter thing. Also also, whatever you spin is gonna be pulling a lot of G's. It's gonna have to have a VERY high tensile strength and I don't think plastic would be able to handle it

      @Egerit cheers I’ll give it ago. One issue could be the axle just twists as the speed increases. Will be interesting :)

    • Egerit
      Egerit Year ago +1

      @GazR's Extreme Brick Machines! If the line's kinda long, you wouldn't have to spin it that fast. Now whether you end up doing it or not, that's up to you but with your skills (and your vast supply of lego motors it seems) you totally could I think

    • GazR's Extreme Brick Machines!
      GazR's Extreme Brick Machines!  Year ago

      Hey there cheers for that! I wish I had a better camera to film stuff like that! So far I can’t find one within budget!
      I have tried something like a stick and even though it was 1-2mm wide the drag was overwhelming!
      Im wondering if something like a tin foil disk would work!
      I do have this tiny nylon line which is just about invisible to the eye I could also add a little glue to the end to give a little weight!
      Will be interesting, personally I don’t think I’ll do it.
