Video is 86 years old, still better explained than most people would explain it today. Easily the best tutorial on the internet. Great job to the creator.
I cannot imagine who nowadays would put this much effort into a explanation video. At some point they showed us 5 dudes in 5 bikes just to tell us that something rotating farther away from the center of a circle moves faster than something closer to the center. Or they made like 10 specific metal parts only to show in the video for like 10 seconds. Anyone doing this video today would think that would be super counterproductive, I wonder if times like these would ever come back.
it's not outdated if it is relevant, i seriously doubt that gear and sprocket design is gonna change any time soon, given it is the same for at least 3000 years
I agree with that. I have returned to this video several times in the past few years. I like the production value, clear technique and clarity of explanation...if only I could remember.
They showed you how, they showed you why and they started off making it fun. They set our brain into ease first with some acrobatics in the beginning. This video was more entertaining to watch then any reality show out there.
It's funny isn't it? Most people wouldn't give two craps about a technical video like this one made today. There isn't any style or class anymore. a majority of people couldn't change their own oil if they had to, or even drive a manual transmission car. It's sad. Cars and their tech used to be common knowledge, and now even a basic carb'd engine is foreign to most people. It's sad really. It's actually refreshing to see this video have 6.9 million views. Faith in humanity is kinda restored. lol
Will Thornton Most things taught in school are forgotten due to improper learning techniques. It is in our best interest to make simplified learning videos on all subjects and how things work. Currently only a small percentage of the population is focused on improving, inventing or updating our technology in general. If the majority understood how all current technology work, then out of all that brain power you would have more people invent new things or update current technology. It will speed up our advancement in general.
All explanations of complex subjects should be like this tutorial: start with a simple concept and slowly add in details step by step until the whole thing is explained. This tutorial was beautifully done despite its age.
Truly is BEST tutorial. Instead of just giving you the way differential works, this video explains how and why the differentials are designed like this.
+VIIflegias This system has a flaw. However, I would agree that it is a wonderful job. We have limited slip differentials in cars now to correct the flaw.
I still didn't understand. Well it could be because of me having the attention span of a sloth But what I understood is that with this type of gear were now able to put speed on the wheels we need according to the way we turn our steering
Very clear easy to follow & understand. Videos like this should be brought back & shown in schools today. Never know who it may help to inspire the next..........
Engaging video that doesn't need humour or distractions to keep the audience interested, unlike today's videos that think we have a very short attention span.
+Chris P. ENGAGING VIDEO THAT DOESN'T NEED HUMOUR OR DISTRACTIONS TO KEEP THE AUDIENCE INTERESTED, UNLIKE TODAY'S VIDEOS THAT THINK WE HAVE A VERY SHORT ATTENTION SPAN.
I was actually joking, but since you would like to be a dick; let me point out that your sentence is incomplete. *This is an engaging video... Also, the way you have wrote this it looks like you are saying that the videos themselves think people have short attention spans. Shouting in broken English doesn't make it any more coherent... Finally, typing in all caps just makes you look stupid.
This goes to show that modern instructional videos suck. This video describes everything in a profesional way without having to loose the viewer. I give this video a good 100 spokes out of spokes on a gear
Good point, however I'm simply saying this out of annoyance when I try to find something to be explained to me. It just so happened to be this video, that I found it to be good. That's all :).
Jam Handy made a lot of films for GM and instructional films for the Army. Search "Jeff Quitney" and "wdtvlive42" on TH-cam, they have a lot of similar films.
Almost got it. actually , more students equates to more funding. Absolutely nothing to do with learning and even less to do with understanding anything.
ive learned more about cars and their components from watching these black and white films than almost anything "new" on youtube, including complicated things like torque converters. mostly due to the use of physical models that go from simplistic to show the basic principle and get more advanced to show exact operation and all features as opposed to cgi or just pointing out parts of a disassembled unit. makes me wish we could go back to that age where people actually learned things about what they owned and knew how they worked so that instead of replacing the whole engine when it breaks down they know just to replace a gasket or whatever.
Very true, but the thing is, this is a consumerism culture, they want to keep it that way, it creates a bigger paycheck for them, and they themselves are caught up in the consumerism society, it's a self corrupting system, the longer it moves, the more corrupt it gets, until it collapses under itself.
I don't usually comment but that was easily the best explanation of a differential I've seen. Love how they go from original problem, to solution, to refinement and so on. That procedural explanation was fantastic, feels very practical an unencumbered. And the effort needed to make all those models and the dramatic way they run on the sides of the wheels at the end there all to illustrate a point... beautiful.
I was born in the 70's but goddamn I love the pre-50's! Especially the advertising tactics. Don't get me wrong, the US had plenty of propaganda, but the advertising of consumer products was done using education and demonstrating benefit, not this preying on the emotions and insecurities shit you see in today's marketing.
Nintendo101maniac 100% true. Almosr every month we have a fucking holiday that is rooted in consumerism. Valentine's Day = flowers and candy. Thanksgiving = turkey meat and turkey fryers. Independence Day = fireworks. St. Patrick's Day = corned beef and anything green. Halloween = costumes and candy. You get the point. And if the corporations don't make a million dollars over last year, the shareholders throw a hissy fit, threaten to vote out the chairman, and it makes the 10'o'clock news that Halloween sucked this year for those industries because they didn't make an extra million or two over last year.
Best explanation I've seen in 69 years!! I always knew what a diff DID but never quite fully understood the :how" bit, Now, thanks to a 1930s film, I do!
This makes so much sense now. i was like how the F does a differential work and then i found this video. i can't find a video better than this one. amazing for its time.
See THIS is what I was looking for. Why are all of the modern videos so hard to understand? This is simple and I love how there is a SIMPLE demonstration.
No wonder people seemed so smart back in the day, with the simplicity of explaining complex phenomenon everyone was guaranteed to learn! These these its all about how many words you can fit in one minute that qualifies as a good explanation.
Brilliant!!! Never explained better. This explanation was spot on, it used a totally unrelated event that is linked to the differentials in principle. That is of the riders, it got you understanding the concept in small increments as it went along and that is one of the best ways to learn anything. Get people seeing relationships with things seemingly unrelated that they are more likely to get and incrementally increase the complexity while still using examples we can relate to and clear concise language. Nowadays everybody wants to show how smart they are by using all sorts of technical jargon only insiders know. Exceptional piece if you ask me. Funny how dumb we get the more we know and the more advanced we get.
I've been working on my own cars-and with my pops on all my family's cars-since I was very little (something I'm doing with my son, too!). I've seen many diffs taken apart, and I understand well what they do and their purposes, but I never completely understood HOW they work until now. Thank you 1930s General Motors, and thanks to the people who still appreciate these great old engineering videos enough to post them so other people (with good taste) can enjoy them, too. They really are super cool, and it's sad you don't see vids like this anymore from car companies explaining their new tech... Thanks again!
This explanation is clearer & more logical than many modern videos. I came here because Steve Mould's explanation of spintronic junctions wasn't good. He said they're like differential gears but should've described it like this old clip did.
OMGOMGOMG, exactly what I've been looking for all the time! Geez, I swear, a 1930s B&W video does a much better job of explaining things compared to videos nowadays. Thank you, uploader!
This video really helps you grasps the concept on how a differential works. By explaining in simple terms in sporks, to eventually transforming it to a more complicated looking gear differential. Yet essentially the principle is the same.
Absolutely the best demonstration of how/why a limited-slip differential DOESN'T work when you need it. Remember all of those times when ONE wheel would spin (the one on ice, in mud or loose sand, or left hanging high over a pothole) while the one with traction does nothing? Yeah, this is why.
you mean why a limited slip diff works? because it would prevent this by limiting the difference between the two wheels, making sure one cant be full speed while the other is stopped
In my aim to learn useful information on a variety of topics (history, tools, technology, techniques, etc.), I come across many videos on TH-cam from pros, hobbyists, enthusiasts, DIY'ers, etc. covering a wide range of categories across the spectrum of our collective knowledge. I will scan through comments if I find added value, but very rarely comment (usually find a bunch of trolls). After watching this old school video I felt compelled to comment on its exceptional effectiveness in the explanation. My feedback relates to both the instruction provided by the narrator as well as the visual walk through of the problem followed by the progression of improvements to the final solution. We rebuilt an off-road buggy style go-kart with a live axle setup (axle rotates both rear wheels at the same speed). The problem at the core of this video is very apparent with the small scale setup of this kind of go-kart - you can easily push it on the pavement in a straight line, but cut the steering wheel and one rear wheel starts dragging, virtually stopping the go-kart. I understood what the differential does, but now I have a solid understanding of how and why. This video was outstanding, but I will add, take note of the video description, as the first minute or two is a bit slow. Just hang in there or skip ahead. Anyone wishing to learn the fundamentals of how this works won't be disappointed. Thanks for uploading this video. I very much enjoyed it.
I love old videos like that. All this CGI crap has no human touch. I was actually half expecting that couple at the end to be running on the drums while lighting a Lucky Strike and sipping a scotch and soda.
Haha! Boozing up in the breakroom during lunch before jumping back on the lathe or in the paint booth with no mask with lead paint, slapping the secretaries ass. What an awesome time that must have been.
Well, how about that. I have worked on cars all my life, and even when explained to me I never quite caught on to what exactly went on inside that chunk. When it's laid out in an A- B-C method it's not complicated at all. Thanks for that.
I never even how one worked. So, I paused at 3:46 to try and figure out my own design, and I imagined a free wheel sprocket like on a bicycle. They broke it down to individual points of contact, and then to two gears that can freely rotate past a fixed gear axle, and that rotation of those two gap gears moves the other axle forward. Plus, they emphasized on gaps in spokes and smoothness. Its an amazing explanation.
Amazing how the principle and concept are explained in a gradual fashion, from a very simple design to a real and complicated one. When it comes to teaching, knowing is the first step. However, how to teach is a whole new field of expertise. And this short video excels in that.
I have watched both modern computer simulations and this video from 1936. Believe it or not....I learned and understood more from this video than the high tech one. Awesome video, Sometime, simpler is better. Awesome.
WOW WOW WOW!!! I have been looking at diffs numerous times to understand how they work, but each time I reach a point I get confused.... This tutorial is horribly old, but is awesomely great! In just a few minutes I get to understand a diff finally completely!! :-D thanks thanks thanks
late response, but anyway: with an open differential, if one wheel loses traction completely, all power goes to that wheel, spinning it in place while the tire that has grip will not move.
Cause Chevy didn't make a 327 in '55, the 327 didn't come out till '62. And it wasn't offered in the Bel Air with a four-barrel carb till '64. However, in 1964, the correct ignition timing would be four degrees before top-dead-center.
from gpt4: The tutorial you're watching, if it's the famous video that's often shared online, was likely made by General Motors Corporation (GM) for the New York World's Fair, which took place in 1939 and 1940. The purpose of the video is to explain the mechanics of the differential gear in automobiles in a simple and understandable way. Differential gears are a critical component of all modern cars. They allow the wheels of a car to spin at different speeds, which is necessary when the car turns. During a turn, the wheel on the outside of the turn needs to spin faster than the wheel on the inside, because it has a greater distance to travel in the same amount of time. The differential is the device that splits the engine torque two ways, allowing each output to spin at a different speed. The video was a part of GM's effort to educate the public about how cars work. The more a person understands about their vehicle, the more likely they are to maintain it properly, appreciate its value, and potentially invest in higher quality vehicles. It's a form of content marketing that many companies still use today. The film you're referring to, known as "Around the Corner," was produced by the Jam Handy Organization, a pioneer in industrial films and visual education. This group was led by Henry Jamison "Jam" Handy, an Olympic athlete and successful entrepreneur who used his company to create thousands of educational and promotional films over several decades, many of which were for General Motors. "Jam Handy" wasn't a division of General Motors but was a separate entity that worked closely with GM (and other companies) to produce these kinds of films. The "Around the Corner" film, specifically explaining the differential gear, was created in 1937. General Motors and Jam Handy had a long relationship. Handy's company produced training films for GM's employees, promotional films for potential customers, and instructional films for the general public. These films covered a range of topics, from the mechanics of different car parts (like the differential gear) to the virtues of capitalism and the free market. These films were part of a broader movement in the early 20th century to use film as a means of education and propaganda. With the growth of car ownership during this period, there was a need to educate the public about how cars worked, both to help them maintain their vehicles and to make them feel more comfortable with this new technology. "Around the Corner" and films like it played a key role in this educational effort.
This is an excellent example of how a training film should progress. The major manufacturers of the era were investing in the youth by educational design projects like this. These kids went on to develope many things still in use today.
Excellent video. Clearest explanation of a diff. I've ever seen. I love the "stiff" quality of the commentary. Of course he annunciates really clearly to compensate for the lower sound recording quality available at the time.
No wonder America is so great today. Look at how well educational videos were back then lol. We need to get back to taking education seriously. Today's videos like this will put you to sleep.
Watching these videos makes me appreciate engineers. Small but genius inventions like these are the stuff that literally turns the gears of our society.
At last I understood, how differential manage the two wheels runs on different speed. Even one wheel stops and other wheel moves with help of differential. This is the best tutorial. I suggest it to those who want to understand how differential works as well as I also recommend it to even such people who know differential working. They would also appreciate it
At 7:57 : " A shaft in the middle of an automobile would be inconvenient for passengers and awkward for luggage". Not to mention a high speed rotating shaft next to your feet would be a bit unsafe? Lol
+Максим Больбасов Btw...I think these Jam Handy films are awesome and very educational. Even in this day and age! We all know it's Chevrolet advertising ofcourse but they made no secret of that.
yknow, im glad i gave this video a chance. my first thought was its old so maybe its outdated, but i stuck with it. one of the best explanation videos ive ever seen.
+Hurdalık Cini In besiege I was able to make one but it took me about 5 hours before I fixed the problem try moving the entire thing upside down and then move the bottom (now top) to the left a bit
+Terra Gamer64 wow you made it? so youre good at building games i recommend you the game gearblocks if you still havent played. its better than besiege in mechanical respect but needs more interactive environment. there is a built in differential gear block in the game btw:D
Video is 86 years old, still better explained than most people would explain it today. Easily the best tutorial on the internet. Great job to the creator.
97 years old now😅
@@csaszargyula19491936 plus 97 equals…. holy shit I’m late for work!
Prime example of how old doesn't mean outdated. This is by far the best explanation video here on YT explaining how an open-diff works.
the diff was the original kind. most cars use slip diff sometimes.
I cannot imagine who nowadays would put this much effort into a explanation video. At some point they showed us 5 dudes in 5 bikes just to tell us that something rotating farther away from the center of a circle moves faster than something closer to the center. Or they made like 10 specific metal parts only to show in the video for like 10 seconds. Anyone doing this video today would think that would be super counterproductive, I wonder if times like these would ever come back.
it's not outdated if it is relevant, i seriously doubt that gear and sprocket design is gonna change any time soon, given it is the same for at least 3000 years
made in the 30's still better than modern videos
I agree with that. I have returned to this video several times in the past few years. I like the production value, clear technique and clarity of explanation...if only I could remember.
it gets to point, not talking about this and that trying to keep your attention
Old mechanical videos do seem to be the best for understanding devices.
straight to the point, and the long ass intro on people standing on bikes....
cok Bagus they are not laser pointers. but they bring it to the point
They showed you how, they showed you why and they started off making it fun. They set our brain into ease first with some acrobatics in the beginning. This video was more entertaining to watch then any reality show out there.
It's funny isn't it? Most people wouldn't give two craps about a technical video like this one made today. There isn't any style or class anymore. a majority of people couldn't change their own oil if they had to, or even drive a manual transmission car. It's sad. Cars and their tech used to be common knowledge, and now even a basic carb'd engine is foreign to most people. It's sad really. It's actually refreshing to see this video have 6.9 million views. Faith in humanity is kinda restored. lol

documentaries... they just don't make them like they used to lol now they're sp boring.
I skipped the acrobatics stuff at the beginning. Saw it, rolled my eyes, and skipped until I heard some explanations.
*Narrator:* In order to reduce the jerky action caused by wide spaces between the spokes, we will put in _more spokes_
*Me, taking notes:* Genius.
I also screamed : Genius ! at that part.
It truly is.
🤣🤣🤣 I thought the same!!! Gosh these explanations are how it should be!!!
there are no videos of modern day that make such great quality learning anymore...

I really just learned basic differential in a 9 1/2 min. video... Amazing.
Good for you 😃💥
I went to a tech school in 2011 to learn automotive repair. This was the video they used. 90 years old and still my go to for explaining it to others.
This goes to show that modern instructional videos suck. This video describes everything in a profesional way without having to loose the viewer. I give this video a good 100 spokes out of spokes on a gear
replace those spokes for teeth and you've won.
Except this video is explaining something super simple, can the same style be applied to more complex ideas and not lose the viewer?
Good point, however I'm simply saying this out of annoyance when I try to find something to be explained to me. It just so happened to be this video, that I found it to be good. That's all :).

i just love these old films because they were better at ilustrating how stuff works wile still making it interesting to listen to :)
do you have other examples of old films teaching stuff? I'm really interested in that. :)
im sorry but i do not know of any other old material like this :)

awsome thanke you :)
the mechanisms themselves were simpler too the engines of today are much more intrikate than this but i do agree that this explanation is flawless
This is brilliant. This is how you explain something. If you want more people in STEM, you need teachers like this.
i have to say it is the best tutorial about how the diferntial works, even better than any 3d example

I have watched a dozen super modern fancy animations and still didn't understand it. But now I do. Simplicity is key.
i still dont understand it
can u help me
I love how they actually mocked up the axle running through the passenger compartment.
ive learned more about cars and their components from watching these black and white films than almost anything "new" on youtube, including complicated things like torque converters. mostly due to the use of physical models that go from simplistic to show the basic principle and get more advanced to show exact operation and all features as opposed to cgi or just pointing out parts of a disassembled unit.

because you are fucking idiot that's why you don't understand
Due to the spring up of consumerism and pop-culture. The whole system is based on getting people to buy just about anything & everything.

I understood what the differential does, but now I have a solid understanding of how and why.
This video was outstanding, but I will add, take note of the video description, as the first minute or two is a bit slow. Just hang in there or skip ahead. Anyone wishing to learn the fundamentals of how this works won't be disappointed.
Thanks for uploading this video. I very much enjoyed it.
I love old videos like that. All this CGI crap has no human touch. I was actually half expecting that couple at the end to be running on the drums while lighting a Lucky Strike and sipping a scotch and soda.
Haha! Boozing up in the breakroom during lunch before jumping back on the lathe or in the paint booth with no mask with lead paint, slapping the secretaries ass. What an awesome time that must have been.
i just came here after watching this topic on learn engineering. and this is way better. i mean way better.
Yeah those 1930 guys are something.
im always in awe at these old videos because of the jigs and modles they make for the demonstrations.
I understood this video's explanation of a differential more than those animated versions lol
Well, how about that. I have worked on cars all my life, and even when explained to me I never quite caught on to what exactly went on inside that chunk. When it's laid out in an A- B-C method it's not complicated at all. Thanks for that.
Same, never really understood the workings of a diff, but this made it so easy to understand using the spokes.
I never even how one worked. So, I paused at 3:46 to try and figure out my own design, and I imagined a free wheel sprocket like on a bicycle. They broke it down to individual points of contact, and then to two gears that can freely rotate past a fixed gear axle, and that rotation of those two gap gears moves the other axle forward. Plus, they emphasized on gaps in spokes and smoothness. Its an amazing explanation.
Amazing how the principle and concept are explained in a gradual fashion, from a very simple design to a real and complicated one. When it comes to teaching, knowing is the first step. However, how to teach is a whole new field of expertise. And this short video excels in that.
OMG :O Cant believe this video was made in 30s :O . The best clear explanation of differential gear out there (y)
I have watched both modern computer simulations and this video from 1936. Believe it or not....I learned and understood more from this video than the high tech one. Awesome video, Sometime, simpler is better. Awesome.
WOW WOW WOW!!! I have been looking at diffs numerous times to understand how they work, but each time I reach a point I get confused.... This tutorial is horribly old, but is awesomely great! In just a few minutes I get to understand a diff finally completely!! :-D thanks thanks thanks
Excellent explanation must say this was d best explanation ever regarding a differential. HATSOFF
This is quite simply a beautiful masterpiece; I think I'm in love with differentials now :)
+The Pain Continues Diffs make it so that you can get stuck in two inches of dust. Open diffs are the devil
Oh, how come?
late response, but anyway: with an open differential, if one wheel loses traction completely, all power goes to that wheel, spinning it in place while the tire that has grip will not move.
70 years on and still the best differential steering explanation video created....
wow may be so called outdated but works way better than any modern video lol
Cause Chevy didn't make a 327 in '55, the 327 didn't come out till '62. And it wasn't offered in the Bel Air with a four-barrel carb till '64. However, in 1964, the correct ignition timing would be four degrees before top-dead-center.
hahahhaha. two yoods
what's a yout?
from gpt4: The tutorial you're watching, if it's the famous video that's often shared online, was likely made by General Motors Corporation (GM) for the New York World's Fair, which took place in 1939 and 1940.
The purpose of the video is to explain the mechanics of the differential gear in automobiles in a simple and understandable way. Differential gears are a critical component of all modern cars. They allow the wheels of a car to spin at different speeds, which is necessary when the car turns.
During a turn, the wheel on the outside of the turn needs to spin faster than the wheel on the inside, because it has a greater distance to travel in the same amount of time. The differential is the device that splits the engine torque two ways, allowing each output to spin at a different speed.
The video was a part of GM's effort to educate the public about how cars work. The more a person understands about their vehicle, the more likely they are to maintain it properly, appreciate its value, and potentially invest in higher quality vehicles. It's a form of content marketing that many companies still use today.
The film you're referring to, known as "Around the Corner," was produced by the Jam Handy Organization, a pioneer in industrial films and visual education. This group was led by Henry Jamison "Jam" Handy, an Olympic athlete and successful entrepreneur who used his company to create thousands of educational and promotional films over several decades, many of which were for General Motors.
"Jam Handy" wasn't a division of General Motors but was a separate entity that worked closely with GM (and other companies) to produce these kinds of films. The "Around the Corner" film, specifically explaining the differential gear, was created in 1937.
General Motors and Jam Handy had a long relationship. Handy's company produced training films for GM's employees, promotional films for potential customers, and instructional films for the general public. These films covered a range of topics, from the mechanics of different car parts (like the differential gear) to the virtues of capitalism and the free market.
These films were part of a broader movement in the early 20th century to use film as a means of education and propaganda. With the growth of car ownership during this period, there was a need to educate the public about how cars worked, both to help them maintain their vehicles and to make them feel more comfortable with this new technology. "Around the Corner" and films like it played a key role in this educational effort.
feel free to look up the turbo encabulator to understand more about the mechanical workings of your vehicle :)
This video is far, far better than the rubbish that is put out today. How good was that clip? Amazing! Thanks for sharing!
This is an excellent example of how a training film should progress. The major manufacturers of the era were investing in the youth by educational design projects like this. These kids went on to develope many things still in use today.
Machines rule the world, we rule the machines. Proud to be a student of Mechanical engineering :)
I'm looking to study mechanical/aerospace engineering too :D
Why can't everything be explained like this.
oh shiz Sakamoto needed an explanation?!
Excellent video. Clearest explanation of a diff. I've ever seen. I love the "stiff" quality of the commentary. Of course he annunciates really clearly to compensate for the lower sound recording quality available at the time.
i feel like i learn more on youtube than i do at school wtf
better than modern 3d videos
This is the best and easiest way to learn the car mechanism system.Thanks for uploading this best video on TH-cam!
Back when America was great!
1930s dude. great depression (sorry idk if this is a joke)
The depression was before 1930.
it was just starting in 1930 and it didn't end till about the 40's
It'll be made great again with Trump
kwas101 Trupm's grandfather time?
"In order to reduce the jerky action cause by wide spaces between the spokes, we will add........MORE SPOKES!"
I had NO IDEA why this was in my queue, but I'm glad I watched it anyway. Fascinating. Engineering is awesome when it's explained well.
this is beautiful
No wonder America is so great today. Look at how well educational videos were back then lol. We need to get back to taking education seriously. Today's videos like this will put you to sleep.
Watching these videos makes me appreciate engineers. Small but genius inventions like these are the stuff that literally turns the gears of our society.
once upon a time we had some damn good ideas here in america.
Probably the best idea was to claim all the even better ideas as your own.
seems to have worked out pretty well back then, we only really stopped being good at what we did when we started listening to those bloody europeans.
waldosan i think the original inventor was british
The Chinese used this 1000 years BC
nonamejustx The first use in a car was in 1897 in an australian steam driven car.
Respect your gears.
At last I understood, how differential manage the two wheels runs on different speed. Even one wheel stops and other wheel moves with help of differential. This is the best tutorial. I suggest it to those who want to understand how differential works as well as I also recommend it to even such people who know differential working. They would also appreciate it
i like the way he says spokes
that was amazing explanation.
I’ve watched a lot of differential videos on TH-cam and this is the best explanation I’ve ever seen/heard. All the others don’t even come close
And if you get this we will move on to positraction for super burnouts!
The days when people were so much more proud of their country, as well as themselves .
Absolutely the best tutorial for how differential works
i think my thumb up was not enough i think if collages and schools made learning interesting like this we will in Mars in the next 5 years
At 7:57 : " A shaft in the middle of an automobile would be inconvenient for passengers and awkward for luggage". Not to mention a high speed rotating shaft next to your feet would be a bit unsafe? Lol
It could be covered in a tube, eh...
+Максим Больбасов Btw...I think these Jam Handy films are awesome and very educational. Even in this day and age! We all know it's Chevrolet advertising ofcourse but they made no secret of that.
aahahah still when the propeller shaft snaps that tube aint saving shit haha
yknow, im glad i gave this video a chance. my first thought was its old so maybe its outdated, but i stuck with it. one of the best explanation videos ive ever seen.
MORE. SPOKES.
3:40 is actually where start :D
the most brilliant way of explanation:
show something awesome and then explain how it happens through small steps and imagery
tried to make this in besiege, it explodes everytiem.
Lol just when I considered trying to
make them
+Hurdalık Cini I like how I am in school but there are game comments on a educational video
+Hurdalık Cini In besiege I was able to make one but it took me about 5 hours before I fixed the problem try moving the entire thing upside down and then move the bottom (now top) to the left a bit
+Terra Gamer64 wow you made it? so youre good at building games i recommend you the game gearblocks if you still havent played. its better than besiege in mechanical respect but needs more interactive environment. there is a built in differential gear block in the game btw:D
ok
