33 Lego Wheels/Tracks on Wood (worst to best)
ฝัง
- เผยแพร่เมื่อ 23 เม.ย. 2021
- 33 Lego wheels, tires or tracks tested on a wooded board to find the best traction. Presented in order from worst to best. Enjoy!
Test method:
adjust the slope angle until the driving car doesn't slide down or climb up but stays in place
measure the angle of inclination
calculate the coefficient of friction = tan(angle)
Potential sources of error:
traction varies along the wooden board (maybe +/- 1 degree of error in spots)
wheel rotation speed varies (faster rotation adds maybe even 2 degrees to the result with some tires, tried to minimize it by using L-motor with large tires)
vibration (happened noticeable only with 15038c03, those errors were omitted)
weight varies (shouldn't matter in theory)
uneven weight distribution on the 4 wheels
angle measurement inaccuracies
== the results are not very accurate, but I'm confident they are roughly correct
All wheels were wiped clean before testing.
The material of the wood board is pine, untreated

People think you access heaven via a stairway
In reality, you access it via a 49 degree wooden ramp
Let's hope our souls have the right friction coefficient to make it.
I hope not. 49° is steep!!!
in real reality, you access it via [Made in Heaven]
that's why "stairway to heaven" is actually a bad song

@Red Bird ‘educational videos’
Why are these videos so scientific, feels like I'm supposed to write an essay with this as one of the references
Pretty much, yep
Dude what are you talking about? Did you forget? It's due tomorrow!
@@aspicboat shoot
I loved watching the statistics afterwords, it was so interesting. Fyi I'm a massive nerd mby that's why i like this stuff lol
OK no kidding in Finland in the A-level tests or matriculation examination tests they sometimes use videos from which you have to base the answer on and I could definitely see this being in one of those tests. I mean if movies can be on them, why not this? Especially because this guy is Finnish.
Let’s appreciate how long it took to switch out 31 different sets of wheels and test them one degree at a time
... and recording it all, sorting through and editing down all the footage
Probably checking batteries between runs too.
didn't only switch wheels, also had to change the deisgn for almost every wheel/track due to shape and size differences
and putting all the data in an excel to get graphs....
Normal covid lockdown day? 🤷🏼♂️
0:36 Imagine being a massive caterpillar track capable of moving on any rough terrain, only to get beat by a wheel so small, it makes the car look like it came out of a 98 year old Alabamian that had a family tree more circular that the wheels itself.
to be fair, tracks arent meant for smooth surfaces.
Tracks are as much about spreading the weight across a greater area than pure traction on a flat surface. (They also have an advantage in not needing pneumatic pressure, so can drive over things that would puncture and deflate a normal tire. this does not matter as much in the Lego world.)
ever heard of pressure per square inch? thats whats happening here, the smaller the wheel the smaller the area of contact for roughly the same weight, so there is an increase of pressure on those 4 points of contact improving grip/friction
that is also why those small plastic wheels at 0:10 are the best ones on the plastic group
@@DrRedstone172
for solid, smooth terrain, small wheels with decent weight being supported make for a better source of friction
for solid, but somewhat rought terrain (such as Roads and non smooth concrete surfaces), a medium diameter wheel or large and wide wheel make better sources
for rough terrain, with variable softness, catterpillars work best
I was thinking the same thing lmao. Poor massive tracks getting clapped by those tiny ass wheels.
The last scene with the wheels shining in the sky and the piece of wood going out of the clouds, soooooooo funny!
That's where old tires go, tire heaven
With that bgm 😆😆
That clip hit me emotionally

I had no idea Lego has so many wheels and tires.
Lego is the biggest tire maker by unit number. Nobody produce more tires than Lego.
Lego tires are awesome
@@norad64 One surprisingly true fact.
The question is whether they are in stock.
From 0.5 CM to 30CM tire

I don't usually go out of my way to 👍🏻 videos, but this one I most certainly did.
Be sure to use one of them winner wheels so you make it
Was some god tier editing ;)
But was it tilted at 54°?
that editing at the end was glorious
I don't know why it's so funny

What I love about these videos is that it's so simple and yet so entertaining at the same time. Keep it up!
I appreciate the extra effort put into the graphs and showing how different each of the wheels were and how that related to the data.
"Yes, Mr. White! Yes, science!"
Never thought three lego wheels with cloudy background could be so epic.
I was wheely excited when this video popped up. I hope this gets traction with a wider audience.
😂😂....(keeping your day job, I hope?)
Ha! "...wheely excited..." is so funny!
i really like all the graphs at the end they add so much perspective and insight
"Thank you for calling The LEGO® Store how may I help you today?"
"Yea I'm looking for the 32020c01 in a 235/50r-18W size"
I am so glad this channel exists, keep it up.
I wonder if Lego changed their rubber compound at some point, or if the older wheels harden over time
they do harden over time, but the old ones were still much harder when they were new.
The older tires are still produced new today just in less quantity right? so wouldn’t they use the same rubber as the new ones, I highly doubt they would change the rubber for the older wheels

This is the best outro I've seen in a *loong* time
In a few years he's gonna bring the transformers to real life
In 2030: Make giant wheels out of Lego treads.
In 2032: Make an RC vehicle that can scale geological features.
In 2040: Make an RC vehicle that can travel between dimensions with special dimension transformers as wheels.

very good!
I liked the animation at the end!
😊 rsrs
👏👏👏👏
That outro was epic
Love your videos man. Always gets me excited when you upload
God i love this channel. No intro, no bullshit, just straight to the facts in an easily digestible, yet engaging format, and an outro to add some comedy and personality. The perfect mix.
This is one of those rare channels where you stop what you're doing to watch their latest video.
The editing at the end tho _chef's kiss_
legit the most entertaining 3mins and 1 second of my day
The animated bit at the end really got me, with the wheels riding the board in the sky :')
10/10 on the end result screen
That final animation of them rolling into space was over the top, and I'm happy you went with it.
did not expect this to be this epic and dramatic
Was there any correlation between the order of the tests and the results? Could be that wheelsdeposit smal traces of rubber on the wood, making it grippier over time.
I love this channel.
Serious yet hilarious, pointless yet informative. A beautiful paradox. Please never stop!
Wow, the graphs and their analysis was really incredible, love to see it. Great content!
I'd be curious to see how a clone turbo tank's wheels would go
Amazing...!
No introduction, just content. RESPECT
I enjoyed this way more than I thought I would. Even the ramp to the heavens! Wonderful!
Quality content like this is the reason I am on TH-cam
2:59: morning wood be like
Lmfao
Thank you Brick Experiment Channel, I really needed this.
This is really great, thanks for taking the time and effort, and then managing to condense it into a three-minute video!
Not sure how long building these takes etc but honestly I’d 100% watch a live stream of you building new designs and testing them
@Brick Experiment Channel, Tom is on to something here. Recently, I guy on Twitch (which livestreams nearly everything) made of $20k (some amount like that) of streaming his sleep for a few nights and having people try to wake him up (via the Twitch channel, I guess). You should really look into this.
Wow, thank you very much! This is really useful!
I'm surprised tracks perform that poorly - I guess they really are more of a solution to vehicles being heavy and needing to distribute their weight across more axles, or something?
It's heartening to see that traction has been getting better over the years.
Tracks are mostly intended for soft terrain.
Especially these rigid tracks offer next to no grip on hard surfaces since there is very little surface area actually in contact with the ground.
Its why the rubber grousers on the tracks improved the grip so much, might look like a smaller contact patch, but all of that contact-patch is actually gripping the ground, rather than only part of the track surface gripping.
Bro, you are amazing! I love your videos, not only for your use of legos and mind blowing creations but just how you can make a technical study over the performance of lego mechanisms super interesting. I have never seen you use terrible music or have annoying long rambling explanations or weird paid promotions in your videos at all. You are just straight to the point on experimenting keeping a very professional manner and focus on your topic. I love this channel and all your videos are truly phenomenal. I look forward to the future of this channel whatever formula you have for making these videos do not change it. Also I do appreciate your small implements of humor in the videos especially when u made the wheels at the end fly up into the sky on the board. I just can’t enough of your content please keep it up.
I never knew how much I needed this video
does weight play a role too?
edit
and does the diameter of the wheel affects its torque?
Yes diameter effects torque since torque is related to force by F = T / (r x sin(a)) where r is the radius of the wheel or length of the lever, F is the force applied and a is the angle between the force and the lever. If we draw a line from the axel to the ground through the wheel we can see the force is applied at 90 degrees to the lever arm and sin(90) is 1 so we're left with F = T/r. This means increasing the wheel radius for the same torque will reduce the force that the wheel applies to the wood.
Watch this while high, it's a whole different experience
Soo true. The ending blew my mind
Love this channel, thank you for doing more rc related content. XD
Bravo 👏 Act 3 brought a tear to my eye... As the wheel rolled away 😢... Beautiful
SUOMI!
And they're climbing a plankway to Heaven 🎶
Easily the best video I saw this week. Loved the ending.
when these 0:55 tiny ass wheels do better than monster truck ones
This was a rather interesting one. Great video as always!
Dude the video quality in this vid was top notch! Nice work!
I thought the music was uncharacteristically dramatic... and boy was I right. I just (re-)discovered this channel and I'm quickly growing to love it.
These videos are so intriguing to see watch! Looks like something we should be taking notes on!
The "Data is beautiful" music just fits haha
I love this channel. Never change!
The production value of this content, it's off the charts !
I never thought I'd experience this in my life, but here I am. And I'm grateful.
Loved the ending with the wheels ascending the slanted board up to heaven!
This entire channel is just perfect. It was a really good video but the graphs at the end made it great
Now I know which wheels I should start selecting for a drag project, I'll go with the ones that have more rotational mass distribution toward the rims
it's always a highlight of my day when BEC uploads.
Watching those gears and threads spin is satisfying
I didn't know why I needed this but, thank you.
I’m proud of this channel man I was watching this channel since 400k subs and now it’s 1mil subs congrats man.👍
From an engineering perspective this is very helpful to know. Thanks for performing this experiment!
Now this is the part of Statics/Dynamics I'm actually interested in!!
The video nobody asked for but everyone wanted, what a legend🤝🎩
Well presented content with details and information in the description. Good work 👏
Your editing skill is improving every time! Love your vid
Holy the work you put in these vids is great!
This is a question i never had, but desperately needed the answer to. Thanks for all the statistics and Testung
Love your data-presentation this time
Would be a pleasure to see that in every video
This is not only a good test for wheel friction, but also for teams to have a full list of bricklink links to buy the wheels from! I have always been wanting to get some of the wheels for wro and fll, and now I can finally find it 😅 Thank you!
Super cool that you included the coefficient of friction
Ah, another important piece of information to fill my brain-case.
@Latest Obsession I mean, the brain _is_ inside it, so...
The unbelieveble amition, devotion, stamina and interest to do such a video 😊
Plastic on wood: Doesn't raise up, just a little bit only, weak traction.
Rubber on wood: Does do raise up nicely, big wheels are better, and also the last one (rubber on wood) is also the wheel to improve tire grip.
This video has surpasssed any other content ever created. it is simply the superior form of entertainment, it is beyond entertainment, it is life.
Was waiting fr this
i love how the first frame of the video is just jumping straight into the topic
I'd'nt've thought coefficients of friction higher than 1.00 to be possible, but you learn something new every day.
you don't have an idea how much knowledge you have shared from this!
This is gonna be super helpful for your future experiments I bet.
As an Engineer, I have to point out something about the Coefficient of Friction number, it’s only valid for the lego wheel being tested and the piece of wood. The coefficient of friction changes between different surfaces. Imagine how this experiment might be different if there was ice or sandpaper on the ramp
Dude...u have the coolest channel! I can't wait for more!!! Plus I don't have any Legos to play with so I'll just watch you play with yours!!!
I love this channel. It's just straight, no bullshit, lego science
This guy right here is a Lego Analyst. Full of scientific calculation and testing. Love it ❤️ Keep up the good work
I would love to see a video comparing the efficiency of different gear combinations. Are certain types of gears (spur vs. bevel vs. turntable) more efficient? How about parallel vs. perpendicular connections? What are the most efficient ways to achieve desired gear ratios? etc.
I like your sense of humor.👍
I'm so happy that the yellow ones are on top and those were my favourite wheels for a long time
I love your effort into this
from the depths of my heart i want to congratulate 32077c01 32020c01 and of course the spunky coming from behind cinderella story 6595c01
so proud of you three!
This video made me very happy.
