- Motorized Toy Car Challenge video devloped to illustrate concepts in the curriculum: gear speed and direction, circumference, diameter, radius, combining different size gears, driver gear vs driven gear, gear trains, gear ratio, gear friction, gear pairs (compound gears), lever arm, torque, rim force
This is the best video on gear ratios and compound gears, and it seems so ancient.
accurate never gets old
actually, because of the music, it was probably made in the 90's.
Explaining science to kids are the best videos from back in the day.
Fantastic couple of teaching videos. Thanks a lot for posting.
I just watched them with my eleven year old son, as he is off of school due to the Covid 19 virus. He enthusiastically took the whole lot in. Now he's really keen to make some models with his lego bits.
28 years old and just understanding this stuff now......
i really wish my school actually taught me stuff.
its official, youtube is great.... If only yt was around when I was a kid!
youtube has always been great
bet our ansestors will be jealous
@@zeroone171 The curriculum was actually made almost 30 years ago, in 1990. 10 years ago is just when they uploaded it to youtube. Of course this only supports your point further though, the other guy was just being a whiny bitch about the noise. I definitely never noticed anything even mildly distracting, much less "unlistenable." Probably just some kid who's only ever listened to audio recorded after 2010 with crystal clear audio recording equipment.
boowonder888 RUclips. Google. An internet with literally countless websites containing free guides and reference materials all made readily available to anyone 24/7/365?? I don’t think anything good would’ve came from it if I had that type of knowledge at my disposal when I was a kid to where all I had to do was literally reach into my pocket at any given time and pull out a phone to get any question I could ever possibly think of answered immediately. That would’ve most definitely been a recipe for disaster
@@richard102879 It is a disaster. Kids are going nuts and living and dying by their online status. :P
Best, simplest & most interesting information on gears ever seen ,read or heard. More videos please. Best appetizers for brain hunger!
Nice video , he should mention that when decrease the speed it increases the torque. That's how a car transmission works. When a car starts running it engages the driver gear to the largest driven gear and then starts shifting until get to the smallest one.
Ah yes. I'm finally ready for tomorrow's midterm. :)
*goes to bed*
*shows up to class bright and early*
*the midterm was 3 weeks ago*
Videos like this make me miss my high school science classes. Thanks for uploading.
Very good description of a spur gear.
Basics of transmission:
1:1, output will be the same as the input.
1:2, output will be twice the input. So one input rotation will be two rotations of the output. Effectively covering more distance in the same amount of time. Speed is distance x time and so you get a higher speed.
2:1, output will be half the input. How does this multiply torque? IDK, it just works.
honestly i was just interested on how gears work and this is a fantastic video!
this totally helps with my wood shop homework!
I recommend playing at 1.25x speed. Speeds stuff up a lot..
Good video though!
That was helpful thanks
@@omarmallah5686 lol
Shiv Ahuja no one asked you either.
It didnt speed it up, gear ratios were still the same!
Lol
Awesome. thank you and greetings from Brazil
I like how giant gears turn tiny gears fast and when you connect another giant gear to the tiny gear, that giant gear spins as fast as the tiny gear.
Continue this process a hundred times and you get an extremely fast spinner.
One day you could just turn a handle slowly for a minute and get a fast spinning fan for a minute
I just love gears
And that's how grinding stone wheels are made for sharpening tools.
And then connect the contraption with a flywheel to create a longer-lasting fan
You'll need a lot torque on that handle tho.
@Shiv Ahuja force, just search for any insane gear reduction video where they try to rotate the output and it's impossible
I can watch this type of videos for fun!
Stunning to use in class!
Finally I can go back and watch transmission videos for I have understood gear ratios :D Thanks!
thanks i learned a lot my science teacher sucks
Edit: p.s i hate school
This video is just excellent.
Very informative! Thank you very much!
great video and very clear . l Like this video very much.
Thanks for the video. great help
Excellent!
So useful I love it keep it up 😊 😃
Resourceful....it helped me a quite a bit👍
Good video. I love gears.
A really good video. Gives you a good idea about simple machines. People who cannot applaud the beauty of physics and the brilliance of the human mind shouldn't bother watching it.
can you get more cheesy than that...

what a wasteman
I don't know how gears work so I looked this up its really cool
Excellent. Very informative.
Great vid
Thank you for the video!
Great video 👍
Heck yeah, tnx to this I finally learned how wind turbines turn low rpm to high rpm for the generator. Tnx youtube.
Amazing video.........thanks a lot...
Wonderful and so educative video. Gracias. The Planetary Society, Patagonia, Argentina.
Thnx for video... It's really helpful
wow amazing and more efficient than todays videos
Is there anyway to reduce speed without using gear, belt, chain
great video!
Very helpful, I've been working on something using LEGO and I needed to research how to slow down gear rotation.
Excellent video Sir :)
well done!!
A really good video
So...a high gear ratio means, essentially, that it takes more time for your out gear to complete a rotation than your in gear.
great vid
Thank you for this very informative animation.
I live in France and I try to teach the operation of the gears to children of ten years.
My animation : Engrenages - 1ère leçon (cours élémentaires)
good job !
Thank you. But do you think you can add other gears than just circular gears? What about corkscrew gears and such.
4:16 wouldn't puting another red gear in the middle keep the ratio and reversing the left red gear? Its like, the same thing he did in the video but with a 24 larger gear...
This video is very educational.
Old is gold
brilliant,thankyou
good !
Is pulley system and gear system same?
soo gooood
wow awesome
Educative👍
One of the best of videos I have seen in you tube .Great explanation 🙌
Pamudu123 Ranasinghe 🔥
Whoever invented the wheel is a genius
thanks for this now i can do the vacuum cleaner using 5v dc motor
it goes staight in my mind
it was so so so so so helpful
This video brought back my memories of courage-the cowardly dog
8-5 has now entered the chat. GIRTH
Very nice teaching 👍
good one.,
Adding extra gears also adds extra stress to the motor right?
Hope so?
Maybe?
I want to increase the RPM so it was possible to rivers this process ?
This video helped me through my physics homework on angular speed
nobody cares nub
Densetsu No, specifically you don’t care, I personally care for this guy, and the 3 other people including me liked his comment.
madame mauve 🔥
Wheels. Give em wheels.
wow my high school physics teacher sucked
Indeed.
Great Video clip! Forgive me for butting in, I would appreciate your initial thoughts. Have you tried - Rozardner Lucky Interview Reality (just google it)? It is a good one of a kind product for firefighter interview tips minus the hard work. Ive heard some great things about it and my cooworker at last got great results with it.
Enter.a.name.here 😬
There's a 1920, 1930 one, even easier to understand.
Thanks a Million
I want the book that goes with this video. Anyone know about it; Name, publisher, year of publish? What schools used it perhaps?
Found it, I think if anyone wants it

Thanks
Thanks You're the hero we need
@@ForeverLaughing221 Thanks.
What is the name for the theorem explained at 1:40
Just leaving a comment to let you know you are not the first one to get this video recommended in 2021😉
Fun fact: in Norwegian, we call a gear literally for a 'toothed wheel' = tannhjul
@Pridify Gaming
Sant sant
in portuguese too
Dzięki za info
thank you
useful video
that helped alot
I always wonder how speed reducer works in motor, I mean how do they Reduce the speed. I didn't know that different size of gears will have different rpm. it's awesome. im not in mechanical engineering btw.
thankyou very much.
but a good sound track
Which app use?
Thanks!
very helpful
Sometimes the simplest videos are the best to learn the fundamentals before diving into the depth of machine design
It started off like "ok i got dis" and quickly devolved into "da fuq is dis? da fuq is dat? wat is going on?"
+Bells Jingle i know right
i understand this and im a kid
Thomas Green
no one cares, thomas
got it
me too
everybody knows that first wheel was invented in Mesopotamia.
Nice video , my teacher is used this video to teaches students . I seen it already.
I am here for school but I am smart I like this
This is real science.
GEARS ARE WHEELS
cool 7/10
imagine coming here to learn how to do the create mod
So this is basically how bikes and cars work!
When i was a kid i thought that cars just work with magic, i tried to think how tf could they work? So i just assumed no one knew but now as a teen I know it, its so mind blowing its science not magic
N I love it
I wasn't a live when this video was made
Get off youtube then.
what do you want a medal for that?
Then why the hell do you have a youtube account.
This video was made in 1990. I get the feeling most of the trolls giving you crap weren't born when it was made either.
Thank u ❤
Very informative though.
Great
The first wheel was invented in the age of the Flintstones... well it was more like a rounded up square, but they had it :)
At least Hannah-Barbera taught me that when i was young ^_^
