@@nicks4802 theres a reason they're expensive edit : or atleast the traditionally made ones
If this channel has taught me anything, it's that clockmakers use brass and steel instead of plastic for a good reason.
@@hisyam1664 A big reason they are expensive is that they only work as status symbols, if they are expensive. (And there's no incentive these days to make a cheap mechanical wrist watch. If you want a cheap and good watch, you go with quartz. Or just use the clock functionality that comes with your smartphone.)
Great content, but I preferred no voice over the robot one.
i strongly aggre
@@RandomArcherPlayer yeah it's a part of his channel now
I agree, but I feel like it makes sense in this video because it seemed like he had to explain more.
@@anunoriginaljoke5870 i think he could have done a better job with no voice over because it sounds fake and it is.
Its better this way for easier explanation
This is quite possibly the only channel where they introduced voiceover and everyone preferred no talking at all. Truly a special channel.
Acktuallthy whoisthisgit subscribers too prefer when there's no voice-over 🤓
Can you imagine the riot in the comments if Primitive Technology started doing a voiceover?
its because he used a shitty tts voice after pretty much establishing his channel as a silent channel

The 1:1 ratio experiment was super interesting. It shows the storage of energy in a mechanical form and the tolerance of the mechanism. You could equate it to reaching the top of a hill. You build a tension of energy climbing up a hill, and that energy is rapidly released by means of gravity going down the other side.
Aka potential energy
I’m wondering if there could ever be a practical application for it maybe some sort of “mechanical spring” powered cutting device?
@@lenardstarks5891 The French used this mechanic to kill over 10,000 people during the Revolution.
Oh! I didn’t really understand those experiments until I read this, now I see what’s happening there. Thanks!
@@lenardstarks5891 Kinda late now, but no, this does not make for any practical use. It is highly inconsistant, loses a tremendous portion of the power input to friction, does not deliver any usuable torque on the output and it instantly damages the device, with more rigid parts being destroyed more severely.
excellent video as always, I just personally prefer the videos without any voice over, same charisma as in the original lego games!
Personally I would only enjoy the voice over videos if they were an actual voice, rather than text-to-speech. If the only voice over option is text-to-speech, I'll take the no talking videos for sure.
@@Conorator yea i agree.
Wouldn't call this a voiceover it is text-to-speech afterall
I hate the new lego games because they added voice lines (mainly the marvel games) it really ruins the game hearing voice lines every few minutes the only line my friend and I agreed was funny was a random guy who said "if we cross the street and a main character didn't see us did we really cross the street?" which was an amusing take on the old adverb

I would be curious to see experiments on loss of torque transmitted through a universal joint (the LEGO piece and possibly some MOC U-Joints) at different angles.
;p
He could also do effects with lego driveline angles too, ujoints in and out of phase
In English?
U joints angles need to be set at certain angles otherwise they will cause a vibration. U joints have a quirk that they speed up and slow down twice in a revolution and the angles need to be in a way they cancel each other out
@@CoilB2 ah ok, thank you
The delay in the last experiment was fascinating! It's like a capacitor for torque!
I love seeing people compare this to a capacitor cause that was my first thought too
AKA a torsion spring
Interesting..
The Oscillating Tire is well known in the belt industry. Basically the raised center of the wheel makes more contact, so when the tire steers off to one side the friction pulls it back to center.
I had that idea for the 1:GOOGOL but then I remembered about the insane amounts of torque required to do that. General rule of thumb is that as the gear reduction increases, so too does the torque, this is why vehicles like farm tractors can inch forward at idle if you release the clutch at lower gears.
most vehicles can actually be clutched in without ever touching the gas pedal. below 4 cylinders, they tend to be choppy, but most cars tend to be able to support themselves in idle up to 2nd gear.
You'd never turn a 1:googol geartrain of any kind with all the torque on earth! Even if you magically could, at not very far into the geartrain you'd be trying to turn gears with a tooth speed over the speed of light. This will give you 'issues'. :)
You can park a manual car without touching the gas pedal.
@@liampope1 even if you managed to magically spin it, not only would the gears be ripped apart from the torque exceeding the material resistance, they would also melt just from the friction. so yeah, reaching near-lightspeed using gears isn't an option.
@@zibingotaeam3716 A long time ago when I was new to driving and experimenting with starting from standstill without gas in my Dad's car, I got it going in second with no gas without too much trouble, then into third and fourth all at only idle. Next experiment, start in fifth from standstill, required some gas, but I got it going, followed shortly by the distinct smell of burning clutch. :)
still waiting on the wall climber that uses a grappling hook, that would be awesome!

Thanks for my spambots comment and WhatsApp scammer comments.
2:08 the problem seems to be that the two right ones aren't fully connected to each other.
Exactly. It broke. That’s how that happened.
I legit have thought about that first concept for over 15 years and have always wanted to try it but never had the resources. You have earned a very strong subscriber.
1:22 That's so cool! It's almost like a physical capacitor or something. Probably a bad comparison, but y'all can probably see my point.
You mean spring ?
Yep..and the fact that u can witness it storing energy is absolute madness
“Physical capacitor” You mean like a rubber band?
Unlike the spring or rubberband analogy, its a much better demonstration of potential. The output can't spin until a threshold tension/charge is reached and then the energy discharges all in one go.
@@yousorooo No, that wouldn't be a rubber band. Capacitors store charge until it reaches a threshold, and can output energy after charging for a short time, but their most used purpose is stabilizing voltage. Think of a faucet that keeps changing how much water is coming out of it, and in this example the capacitor would be a bucket with a hole in the bottom. The water would pour into the bucket at irregular rates, but leave the bucket at a consistent rate.
This is seriously one of the best KZhead channels out there.
Still waiting to see Legos mounted with stronger engines. Some experiments might need much more torque than any Lego-engine can deliver.
It is- but I would love more videos 😫🙏🏼

At 1:50 how awesome was that delay from backlash. Reminds me of a train engineer I met and he was telling me about mile long trains he’s pulled and how careful you had to be when speeding up and slowing down because of slack. You could potentially snap a coupler or worse

I’d really rather not have the text-to-speech in future videos. I hate it on tiktok and I really don’t like it here. Just my 2 cents. Great video!
It honestly sounds better here imo
I agree. I hate most TTS voices because of tiktok. There are some REALLY convincing ones but they're either expensive to get a hold of, or you have to design them yourself.
Yeah, literally the only TTS I can stand is talkoid and none of y'all wanna pay for that
@@handlesarecringe957 Neuro-sama's TTS is pretty good too. The VRChat AI called "Celeste" also has an uncannily convincing TTS voice.
Brian tts is definitely a good one
I love how open you are to requests, keep up the good work bud
I have seen snapped pins that seemed to shatter and I always thought, why didn't they make them out of a more ductile steel/temper. This video actually showed how any elastic slack in the drive/cogs actually destroys efficiency and why harder less elastic metal is better.
Mostly due to cost. Sure metal is stronger than plastic if two pieces were identical in shape and size, but it's also slightly more expensive to manufacture, ship, and store. And since it's more expensive to make, the product becomes even more expensive to sell.
@@jessegd6306 metal being more expensive to make and ship makes sense... but not store...
0:30 This is the "crowned pulley" effect. There are lego videos that explain it on KZhead. It works with the tyre because the centrifugal force expands it and it only touches the rim from one spot at a time.

@@spi-bro630 oh
2:00 insane how like zero movement but torque is able to produce so much energy!
It’s the elastic energy stored in the slowest gears
That's a lot of experiments in a short time and no BS, subbed!
This is just seeing how durable legos are through weird experiments and I love it
I don't like the Text to Speech, but it fits this video fine. I like the no talking style of video more
What’s with the robot voice? Your natural voice (think from hydraulic press channel spoof) is fine!
Love your channel my man. Keep up the good work
The fact that he makes these amazing creations (that I do not understand one bit) out of literal Legos is mind bending
0:22 is one of the coolest sounds I’ve ever heard!
It’s a scream bro
@@Eroxallywhale.
Thank you for the answers. That last one was interrsting with the delayed actions.
I love watching these they get my mind back on Legos
I loved that you created this by responding to your fans🤗
Kinda liked the Quiet format better. text Better than text to speech
Loving the experiments as always but I am not sure I am a fan of the text-to-speech voice... The subtitles have always been fine and, to be honest, added to the special nature of the channel. This voice feels like it cheapens it a little.
I know this gets said a lot but I do think this is the best channel on YT. At least for people who like math. You took engineering, and made it understandable through Lego. 10/10 would break in solid metal with plastic again.
The tension building up and releasing is kinda awesome.
I agree with others that text-to-speech is not the best touch. It makes the video feel tacky. Usually I associate text to speech with lower quality channels. This is a high quality channel!!!! And it should feel that way :)
I love listening to the raw audio of the mechanics working or breaking. The text to speech just completely ruins the ASMR effect of his videos.
Your videos are like a Christmas present, I’m always looking forward to them.
Fascinating stuff. There are so many engineering experiments which can be done with Lego, once you establish baseline standards for resiliance.
Nice! Idea: See how gears interact with liquids and some gasses like water, liquid nitrogen, etc. Then compare them to gears in air.
i prefer no voice over
The last experiment is exactly something I was thinking of, but couldn't find anyone doing it. For me it's incredible that both first and last gear are spinning so fast, while the ones in the middle, transferring all that torque, do not seem to be visibly moving!
this is a bot.
They twist the axles to store energy in a miniature version of a torsion bar. When the torsion on one half exceeds the static friction on the other, it starts to move and moves until it dissipates enough energy to match the kinetic friction, at which point it stops again and the process repeats.
Those last one to ones, I love that they technicay are one to one, just not instantly. It just needs to take some time for you to notice its one-to-oneness.

I’ve been waiting for this I love your channel :)
@Cekia Selmi ♋️ no thanks
To be honest it was cooler and more peaceful when there was no voice-over
That last one would be a good demonstration of how stress builds up before and is released by earthquakes.
This is such a cool idea, great vid!!
I prefer the silent videos (no TTS), but this was still a fun watch :) Upvote.
Hearing someone talk, even if it’s just a robot voice, is SO JARRING, I don’t understand why
Yeah I can't stand it, I usually listen to the mechanics work (an ASMR thing) and the Text to speech just kills it. People in the comments say to just mute the video, but if we did that we couldn't hear the mechanics work or break. We can easily read the comments put in the video if we want to without the help of text to speech.
love the new voiceover. Listening to something talk is just such an improvemnt over nothing at all!
love the channel not long discovered it, just subscribed as id love to see more of these tests, I dont know if has been requested before but have you ever tried pulling a car with lego motors and gearing it to make it easy for the motors to pull the weight of a small car along flat ground?
I also discovered a long time ago that the holes in a pillow block assembly don't always line up perfectly. A little trial and error would result in a much smoother and free spinning geartrain.
You have a natural monotone voice, you ever thought of doing recordings for those text to voice thingies? :)
its so monotone that he sounds like a TTS
The last one got me thinking. If the time between the build-up and release is consistent and you know what it is, it could be used as a mechanical clock circuit for other experiments! Perhaps to operate a lever in something?
That last experiment was satisfying as i always wondered, and as odd of a result it was i thought that there would be a similar result, but i didn't think of it as tension and thought of it as charging the gear.
Great experiments! Would love to see more ideas from the audience!!
man i absolutely hate that computerized vocals that have completely inundated the internet recently
this pills gave me much more insights onto mechanics and scaling of forces than any theoric study ever could
first time watching this channel and i’m pretty confused but what he’s doing looks cool
Great video as always! A little bit of criticism though. I'm not sure if the text to speech thing really works. It just repeats text on the screen for the most part. Reminds me of that tic tok text to speech voice that is overused.
Please no text to speech :( Loved your channel since day one but this.... :/ please don't!
Lego has come along way since I was a kid.
This is exactly what I need to be watching the night b4 I have work...

Wow! Its so interesting to guess and then see if you thought what happened correctly 😃. Great experiments! 😉
I have no clue what any of this is and I already watched like 80% of the video... You goddamn entertainment man
i kinda want to see the reverse of the final experiment, going faster and then slower, not slower and then faster. though i expect you'd still have the same torque issues as in the 1:GOOGOL test
Great video as always, but you should skip the computer generated voice in the future :)
This is great, I hope this gets people interested in engineering
'Bent and broken' Thanks for the shoutout, BEC!
Would love to see more videos of lifting weights with lego engines and gears.
The text-to-speech voice is a bit hard to listen to imho. Let me know if you'd like a more relaxing-sounding voiceover :)
Hi. I'm interested. Your voice sounds good. :) Please send me an email (found on About page) or a message on facebook.
@@BrickExperimentChannel Sounds great! Will send an email shortly.
That "back to 1:1 ratio" mechanism essentially became a spring energy storage. It couldn't start moving for a while, then released the energy into the final gear.
I loved the end with "bent, and broken" immediately into "thank you." Like a very sarcastic "thanks for breaking my pieces"
1:19 That is totally different from what I expect the inside of the clutch gear to look like.
Would be cool to see a combination of the pulley/gear systems and the press to make a crazy powerful press
cool name bro
@@olololo9206 its a bot
Thank you for doing this, most KZheadrs call the comment suggestions stupid and never try it, we know that some suggestion in the comment section is dumb, but we just want to have some sort of interaction and connection with our favorite KZheadrs.
I would love to see someone make high performance metal Lego parts, that you could swap in for experiments like the up and down gear ratio one, so you could replace the parts that are definitely going to experience plastic deformation under that amount of stress and see if you can get the whole mechanism to actually overcome the built up resistance.
The last one seems like a fantastic idea for what is essentially a mechanical capacitor. A wind up spring is more like a battery, but this could be used to mimic that electric delay from a capacitor charging and discharging. We may be getting closer to fully mechanical computers every day. A steampunk fan’s dream!
This is satisfying to watch
It's awesome you listen to your fans!
I may not understand a second of this video but I still love it
I've seen some comments saying they liked it without the voice, but I really enjoyed it! Maybe upload two versions of each video unless that's too much of a burden. Either way, keep up the good work!
Very neat. Wonderful idea. And you take requests. Respect.
I really love this channel, also, can you make a very fast gears mechanism with high torque?
Is this a voice reveal? :)
No. It's an AI text to speech program.
@@jadenfernandez9448 Not even necessarily AI

Based on my reply, I think they're right.
1:02 legit asmr
Alright, time for a googelplex now!
Love this. If I was to replicate some of the stuff that you do here. What Lego set would be able to get me started?
you should make metal gears to make it durable and beautiful 😄
If a functional 1:GOOGLE was even possible. I'd be curious to see how far back on the gear train it would go before the gears shatter from centripetal force
Yes, id like to see it used with one of those enormous solid steel flywheels.
A hundred cogs each 10:1 would give you a googol ratio. Obviously you would build such a thing out of actual engineering steel rather than a childs toy set, but it certainly is possible.
That last experiment was amazing
you know what while watching this video i just felt joy thx
This is really cool and I like how people pointed out that it's storing energy and the slow-moving gears! This made me wonder; when the gears start spinning 2 minutes in, if you stop the motor will the gears spin for 2 minutes? Further, once tension builds couldn't you lock the gears and release the tension later? Super fun channel, thank you; take care and God bless!
We know we can store energy in a deformed LEGO gear train. We can experiment to learn how much, and for how long. There will be virtually endless ways to improve the energy density. Sounds like fun.
Your describing the principle behind wind-up springs. The time that the gears keep spinning has more to do with how the tension is released; in the real-time part of the clip, the output spins much faster than the input, even though the mechanical advantage is the same. The total energy that comes out will be less, however, so it won't spin for very long. All of this can be observed in a wind-up music box: It plays music for much longer than you spend winding it, and your sure that there's still some energy left inside when it stops.
I love questions like this. They lead to innovations like wind-up springs.
1:30 is this what real life lag looks like?
