But what happens when one wheel is lifted off the ground? It will spin freely while the other wheel on the ground gets very little torque. This surely gets people stuck in snowy situations.
@@sqlexpThis is why limited-slip differentials exist. The one in the video is a simple open differential, or 100% differential, since it allows each wheel to spin independently at any speed.
Forget about the differential, this is a masterpiece of education. Such an elegant and simple way of explaining this so that literally anyone on the planet could understand it. If schools were as good at teaching as this video is, the world would be full of geniuses
Nowadays tertiary education is just some researcher forced to teach lessons. So they stand up and read some slides, the students go on and teach themselves. Educational material that are clear and concise like this are seen as spoon feeding.
@@jessebeegee If it were that simple, we wouldn't be having dozens of the best-funded public schools in the country failing to produce a single student who can pass their math exams.

Before, even encyclopedias was more comprehensive. I read three editions of Big Soviet Еncyclopedia, and in the edition of 1937, one could read how to make explosives, powder and guns.
The showing of progressively more & more spokes, morphing into sprockets, then gears, really hit the principle on the head of what's happening. This is an excellent verbal and visual explanation.
Well I'll be damned ... I've always known the function of the differential, but it took a General Motors 16 mm film clip from the 1930's to explain simply and clearly how the dang thing works. Keep in mind, folks, these film "shorts" were viewed in movie theaters before the main movie - there was no T.V. in the 30's.The reason for the motorcycle stunt team at the beginning was to add an element of entertainment to the film.
I let's not forget to support artist and such now a days everyone just want to use as little money as possible. now most art people have at home is copied in the thousands and bought at Walmart, instead of supporting a local artists.
And most of all... it doesn't insult our intelligence by demanding 'click to subscribe' before we've seen if the content is worth beans. I've arrived at the point where if that's how a video opens, I will definitely not subscribe even if I like the presentation.
no the engineers weren't ahead of their time. its everyone else that's behind. its really not hard to pick up a book and learn something or to experiment on your own. most people are just lazy and want to enjoy others hard work.
We just don't teach like this in class or college anymore. Only way you'll get such a full explanation and reasoning on something like this is to personally know someone who actually understands it and wants to help you or finding a good TH-cam video.
No CGI, no special effects, no BS. We should salute our early engineers and designers and those who followed them. Wherever they may be... thank you is not enough. 🖖❤
LOL omg asking the real questions! Never thought about saving it, and with politics nowdays its possible we need to carry these usefull informations to next humanity
Its amazing how these people back in the day where able to make high quality videos like these with animations, transitions, and overlays with little to no computer power. Its also pretty interesting how a video from the late 30's is still relevant today
MLG_420 QUICKSCOPE I just watched it again, after all this time, just for the fun if it. People like this guy are truly rare. People that can pass on their knowlage with ease. I had one or to professors like this guy (not in engineering but economics), they could make it so simple and engaging, then there was the 'other' type of professor (the like that never left an education Centre), who was no doubt extremely cleaver, but had zero personal skills, just expected everyone to understand what he was talking about from day one. That guy spent the whole lecture with his back to you writing numbers on a board, losing 9/10s of the class. I think it was Einstein that said somthing similar to "if you can't explain somthing simply, you are yet you master the subject" This guy has it nailed down (or did).
We tend to believe man was less creative in the past. But the way of thinking of a man from the pyramid building time and a man nowadays, is exactly the same. Same creativity, same inteligence. The only thing that improved was the previous knowledge. The problem when teaching things, is jumping basic concepts. The more the teacher jumps, the more difficult to truly understand, no matter if it happened 4.000 years ago or nowadays. That is why we always had and will have good, and not good teachers. The guys that wanted to teach how a transmission and a differential work in this video was a good teacher, with excellent didactic.
Didn't waste time on P C. Didn't have safe spaces. Didn't have 72 genders. Didn't waste time on snowflakes feewings. Didn't have to make sure they were inclusive.
I really appreciate that they started explaining it by introducing a really basic version of the differential. Having the absolute simplest concept of things as a ground to stand on for our comprehension really makes everything easier to understand by people of all levels of intellect. I thoroughly enjoyed this.
Yeah I agree. Seeing something in its full and finished version often overwhelms the mind. But if you see it step by step in a basic way, you can then move on from there with relative ease. This is by far the best video on how a differential works.
No wonder so many people liked tinkering with cars back then, these films really simplify the principles while also explaining its mechanics and composition profoundly well.
Also remember, that it was all so new and exciting then. So many new mechanical principles. Nowadays it's often about how many microchips and micro-transactions you can stick inside a product. xD Man I do miss the "robustness" of those good old days. I do surely hope that we will somehow reach a society again where such principles are viable again.
branot89 wikipedia is the suck at explaining...anything.....if you want to know how something works, grab an old encyclopedia or watch old videos Wikipedia "A differential is a particular type of simple planetary gear train that has the property that the angular velocity of its carrier is the average of the angular velocities of its sun and annular gears."---¬¬¬¬¬¬¬¬¬¬¬¬¬:> that's really helpful....NOT..it's not even correct English

It was probably a series of simple steps when they understood the problem they had, the solution they needed, and what they had to work with. Think of this riddle: "Question: How do you eat an elephant? Solution: One bite at a time". Many seemingly impossibly complicated problems can be solved when you break them down to a series of small, simple problems.
The conventional automobile differential was invented in 1827 by a Frenchman, Onésiphore Pecqueur. It was used first on steam-driven vehicles and was a well-known device when internal-combustion engines appeared at the end of the 19th century

This video absolutely blows every other video explaining differential steering totally out of the water in terms of explaining it. Even the most current 3D modeling programs that you see used by modern creators trying to explain this concept don't come anywhere close to being as affective as this simple demonstration. I mean, I watched like three other videos on how differentials work, and they were all beautifully modeled in a computer program and looked great, but none of them really made it click with me like this video did. The beauty is in the simplicity, I guess. Either way, this video was able to really let me wrap my mind around how this all works, and it's pretty awesome that it was made so long ago.

This is great It doesn't just explain how it works, it also explains why a differential was necessary in the first place and does it with simplicity 👍😉
Except for one thing - a regular differential still only give you a one wheel drive car when it matters as the power will always go to the wheel with the least resistance. Now we need a video on the limited slip differential!
@@nickh5081 I believe open-type differential were either the only type, or the most common differential at the time this video was made. As you said, open-type differentials are fine for spinning on roads, but still a issue when driving on bumpy roads or off-road.
it's the style of learning and what people thought mattered back then and today. In my engineering courses the focus is always on the derivations of things, the grand concepts, but rarely are we simply taught how something works in practice. Worse we get basic info, variables, eqs and have to teach ourselves the complicated stuff. I wish we taught things more simply, less theoretical and more practical since that's what's needed today, there are phds and other people who can work on improving concepts and theories, but we need a hands on workforce who can the job, then we can focus on the inner details. teach the simple stuff first basically, not last.
People don't get more intelligent, we just get to know more things that we use for discovering new ones because intelligent people from the past had make out them.
My tutor showed it to my class in college when we were learning about differentials. When he was learning his tutor showed it to his class (I suspect that past tutor also learned about differentials from this video)
I was amazed how clear and informative this video was to explain plain of reference (there are few videos to watch) th-cam.com/video/bJMYoj4hHqU/w-d-xo.html
Its simple really. General public was not as technologically educated as we are today. Now these lazy bastards that educate just assume everyone knows everything, and would rather tell to look it up online than do the teaching themselves.
My Master (as in, the guy who trained me in my field. Not sure if that term is actually used in english?) used to say: Good, reliable technology is always simple. The more moving or electric parts (including sensors and all that) the more likely that something is gonna screw up. For a bit of context (and a little anecdote to prove him right): Our company was responsible for the street lights in my town, and we were in the process of excanging good old Vapor lamps with some more newfangled high-tech lamps (some streets even got LEDs). The Vapor lamps had a coil that acted as a limiter (similar to a resistor), and that's it. The newer lamps had some complicated electronics, including a ~30€ circuit board. (The Coil for those vapor lamps would cost 4€ I was told...) In the year that I did that particular job, I had to exchange countless amounts of those circuit boards. They broke left right and center, and you could always SMELL it as soon as you opened the case they were kept in... (I hate that smell.) Also keep in mind the company had just begun installing these maybe half a year before I joined them. The Vapor lamps? Maybe five coils the entire year. And we had 10 times more of them than the new ones at that point.
Sapphire EX LED lamps are pretty simple too. The problem: companies that produce them are programming them to stop working at certain time. In fact led lamps, on good quality can last more than 20 years.

It was invented by the Chinese for ceremonial reasons or to instill awe in the simple subjects . On a cart a statue would always point in same direction when the cart turned a corner .
His name was Onésiphore Pecqueur, he was french, and he invented it before cars existed (He died 30 years before the first car ever was built). It was originally used on mechanical watches to allow two gears on the same axis to rotate at different speeds. The creativity of old watchmakers is always mindblowing

You'll be surprised to hear why they sound similar. They're all imitating the "Transatlantic Accent". It was used as sort of a standard in the industry to maximise the efficiency and clarity of speech.
Kind of sad, but it was purposely done. By both the government and the auto industry during the 1960's. (and not really for any super conspiracy, shadow government weirdo, NWO shit either.) The industry nearly collapsed due to several factors at that time. Some of the biggest being, the predicted purchase turn around of consumers, and the open sourced 3rd party auto parts, tools and their availability. It was assumed in early forecasts in the auto industry that the average customer would replace their vehicles every 3-5 years. Thus the industry build itself around that model. However, because of growing public knowledge on repairs, Maintenance and availability of parts and tools. The 3 year prediction was off, waaaay off, and the average consumer owned their vehicle for 10+ years. Which led to MILLIONS & Millions of factory automobiles just sitting there, rotting, and often being scrapped (an interesting side effect being, some of the fist reclamation and recycling facilities began as a result of this) About half of the auto producers went under, others forced to consolidate. In response, the auto industry stopped this kind of stuff. Then made many materials, parts and advancements proprietary and trademarked, informed engineers to deliberately build designs that where complex and difficult to repair without formal training or special tools, and lobbied the government to mandate repairmen and auto shops to hold certifications and "mechanic" to be added as a degree program to trade schools and universities. Which they did, nearly collapsing that industry over night as a result, lol. History is so fucking cool. That's a lot of shit, to explain why a video from the 60 years ago is so informative...by comparison to today.
I think because it took time and effort to design and build the physical models (and it probably involved an actual engineer, mechanic, or expert) they also put some time and effort into thinking about how to best use the models for an effective demonstration (with useful simplified explanations). But these days it takes little time and no effort for somebody (utterly clueless about mechanics) to google up some 3D modelling stuff and get the software to put together a really slick-looking yet needlessly overcomplicated (confusing and distracting) photorealistic computer animation.
Absolutely love how their only two reasons they give as to why having a fast spinning driveshaft running through the cabin completely exposed is 'because it would be inconvenient for passengers' and 'would be awkward for carrying luggage'.
Is nobody going to comment that the centre hump that runs through a car now a days is a thing? Originally in the 50's to now was to accommodate the drive shaft of a rear wheel drive. Even front wheel drive cars still have that hump, for like, no reason.
Because driveshaft will be inside a hollow tube or be covered with something when it's inside the cabin. Engineers wouldn't let that huge of a safety hazard be exposed.
Single best description of differential ever. If it was this simple to explain all along, how did the ability to say it so simply through the years get lost? Silly.
I did a restoration on my bosses ‘65 tbird convertible. All mechanical, the concert those mechanisms perform every time you raise and lower the top is truly a thing of utter beauty.

Forget about the differential, this is a masterpiece of education. Such an elegant and simple way of explaining this so that literally anyone on the planet could understand it. If schools were as good at teaching as this video is, the world would be full of geniuses
Nowadays tertiary education is just some researcher forced to teach lessons. So they stand up and read some slides, the students go on and teach themselves. Educational material that are clear and concise like this are seen as spoon feeding.
That's why it is called as school
that’s what happens when education and cinema/arts get public funding. give people money, it’s really that easy!!
@@jessebeegee If it were that simple, we wouldn't be having dozens of the best-funded public schools in the country failing to produce a single student who can pass their math exams. Public funding might be PART of the answer, but it is not the WHOLE of the answer. If it was, the U.S. public education system would not be such an abysmal failure that we'd actually be doing the kids a favor by shutting it down.
Before, even encyclopedias was more comprehensive. I read three editions of Big Soviet Еncyclopedia, and in the edition of 1937, one could read how to make explosives, powder and guns.
The showing of progressively more & more spokes, morphing into sprockets, then gears, really hit the principle on the head of what's happening. This is an excellent verbal and visual explanation.
Well I'll be damned ... I've always known the function of the differential, but it took a General Motors 16 mm film clip from the 1930's to explain simply and clearly how the dang thing works. Keep in mind, folks, these film "shorts" were viewed in movie theaters before the main movie - there was no T.V. in the 30's.The reason for the motorcycle stunt team at the beginning was to add an element of entertainment to the film.
Not merely to add entertainment, but to grab everyone's attention so they'd watch the rest of the film strip.
I don't see that on Americas Got Talent, amazing how bold men were back in the day. My testosterone rose 10 points just watching that.
this video itself was entertainment!
I let's not forget to support artist and such now a days everyone just want to use as little money as possible. now most art people have at home is copied in the thousands and bought at Walmart, instead of supporting a local artists.
It’s the 30’s, why wouldn’t there be an absurd stunt bit?
this is how you do a proper tutorial video. No loud music, no jump cuts, no flashy distracting animation.
And motorcycles. Lots of motorcycles.
The music is kind of loud in the start of the video but that doesnt matter because it aint some fucking free DIY video music that rapes you ears
Just S P O K E S
Really long intro though
And most of all... it doesn't insult our intelligence by demanding 'click to subscribe' before we've seen if the content is worth beans. I've arrived at the point where if that's how a video opens, I will definitely not subscribe even if I like the presentation.

That guy spent the whole lecture with his back to you writing numbers on a board, losing 9/10s of the class.

But the way of thinking of a man from the pyramid building time and a man nowadays, is exactly the same.

The problem when teaching things, is jumping basic concepts.
The more the teacher jumps, the more difficult to truly understand, no matter if it happened 4.000 years ago or nowadays. That is why we always had and will have good, and not good teachers.

I really appreciate that they started explaining it by introducing a really basic version of the differential. Having the absolute simplest concept of things as a ground to stand on for our comprehension really makes everything easier to understand by people of all levels of intellect. I thoroughly enjoyed this.
Yeah I agree.
Seeing something in its full and finished version often overwhelms the mind. But if you see it step by step in a basic way, you can then move on from there with relative ease.
This is by far the best video on how a differential works.
yeah, i feel like that's the most effective way to teach/explain something
And they show iteration by iteration how it evolves to close those gaps to the more "complex" system.
Thats what happens when someone who truly understands how something works and is able to not only build it themselves but explain it to others.
I really wish this could applied in general teaching.. i wonder how the programming analogue for this would be. hello world?
No wonder so many people liked tinkering with cars back then, these films really simplify the principles while also explaining its mechanics and composition profoundly well.
Also remember, that it was all so new and exciting then. So many new mechanical principles. Nowadays it's often about how many microchips and micro-transactions you can stick inside a product. xD
Man I do miss the "robustness" of those good old days. I do surely hope that we will somehow reach a society again where such principles are viable again.

Think of this riddle: "Question: How do you eat an elephant?

Many seemingly impossibly complicated problems can be solved when you break them down to a series of small, simple problems.
No one actually invented it instantly, it's just a process of developing

This video absolutely blows every other video explaining differential steering totally out of the water in terms of explaining it. Even the most current 3D modeling programs that you see used by modern creators trying to explain this concept don't come anywhere close to being as affective as this simple demonstration. I mean, I watched like three other videos on how differentials work, and they were all beautifully modeled in a computer program and looked great, but none of them really made it click with me like this video did. The beauty is in the simplicity, I guess. Either way, this video was able to really let me wrap my mind around how this all works, and it's pretty awesome that it was made so long ago.

This video taught me basic physics and semi-complicated engineering better than my class can
it's the style of learning and what people thought mattered back then and today. In my engineering courses the focus is always on the derivations of things, the grand concepts, but rarely are we simply taught how something works in practice. Worse we get basic info, variables, eqs and have to teach ourselves the complicated stuff. I wish we taught things more simply, less theoretical and more practical since that's what's needed today, there are phds and other people who can work on improving concepts and theories, but we need a hands on workforce who can the job, then we can focus on the inner details. teach the simple stuff first basically, not last.

Its simple really. General public was not as technologically educated as we are today. Now these lazy bastards that educate just assume everyone knows everything, and would rather tell to look it up online than do the teaching themselves.
Because nowadays, it’s about the shock factor.
That is bloody impressive. Something that hasn't really changed much in decades is extremely simple
No need to reinvent the wheel.
It has changed alot on the cars that can send torque differently to each wheel. Look up torque vectoring differential or watch?v=rQowh2Kr38s.
That still isn't a complete rework of the differential. It's just an upgraded version.
My Master (as in, the guy who trained me in my field. Not sure if that term is actually used in english?) used to say: Good, reliable technology is always simple. The more moving or electric parts (including sensors and all that) the more likely that something is gonna screw up.
For a bit of context (and a little anecdote to prove him right): Our company was responsible for the street lights in my town, and we were in the process of excanging good old Vapor lamps with some more newfangled high-tech lamps (some streets even got LEDs).
The Vapor lamps had a coil that acted as a limiter (similar to a resistor), and that's it.
The newer lamps had some complicated electronics, including a ~30€ circuit board. (The Coil for those vapor lamps would cost 4€ I was told...)
In the year that I did that particular job, I had to exchange countless amounts of those circuit boards. They broke left right and center, and you could always SMELL it as soon as you opened the case they were kept in... (I hate that smell.) Also keep in mind the company had just begun installing these maybe half a year before I joined them.
The Vapor lamps? Maybe five coils the entire year. And we had 10 times more of them than the new ones at that point.
Sapphire EX LED lamps are pretty simple too. The problem: companies that produce them are programming them to stop working at certain time. In fact led lamps, on good quality can last more than 20 years.

Kind of sad, but it was purposely done. By both the government and the auto industry during the 1960's. (and not really for any super conspiracy, shadow government weirdo, NWO shit either.) The industry nearly collapsed due to several factors at that time. Some of the biggest being, the predicted purchase turn around of consumers, and the open sourced 3rd party auto parts, tools and their availability. It was assumed in early forecasts in the auto industry that the average customer would replace their vehicles every 3-5 years. Thus the industry build itself around that model. However, because of growing public knowledge on repairs, Maintenance and availability of parts and tools. The 3 year prediction was off, waaaay off, and the average consumer owned their vehicle for 10+ years. Which led to MILLIONS & Millions of factory automobiles just sitting there, rotting, and often being scrapped (an interesting side effect being, some of the fist reclamation and recycling facilities began as a result of this) About half of the auto producers went under, others forced to consolidate. In response, the auto industry stopped this kind of stuff. Then made many materials, parts and advancements proprietary and trademarked, informed engineers to deliberately build designs that where complex and difficult to repair without formal training or special tools, and lobbied the government to mandate repairmen and auto shops to hold certifications and "mechanic" to be added as a degree program to trade schools and universities. Which they did, nearly collapsing that industry over night as a result, lol. History is so fucking cool. That's a lot of shit, to explain why a video from the 60 years ago is so informative...by comparison to today.
I think because it took time and effort to design and build the physical models (and it probably involved an actual engineer, mechanic, or expert) they also put some time and effort into thinking about how to best use the models for an effective demonstration (with useful simplified explanations).
But these days it takes little time and no effort for somebody (utterly clueless about mechanics) to google up some 3D modelling stuff and get the software to put together a really slick-looking yet needlessly overcomplicated (confusing and distracting) photorealistic computer animation.

When an old ad is more educational than the education system
This was an ad?
@@smmb4818 No, it's an old educational short.
@@googleuser3163 well it’s also an advertisement by Chevrolet
I can’t stop watching
I am blown away with how simple and effective this video is, I didn't even know the rear wheels even moved at different speeds!
Yo tampoco
The front ones as well of course
@@andreasa.2226 I knew the front did, didn't know how though!
@@KHAinnovations menos yo
@@Tencryn the same procedure for the front tyres too but if the vehicle is 2 wheel drive the wheels will be attached separately
Кто ясно мыслит, тот ясно выражается! Никогда не знал как, это работает, за пять минут стало ясно с первого раза.
Не смотря на не слишком высокий уровень английского у меня, все абсолютно понятно, мне кажется даже без слов было бы понятно
This is the best description of how a differential works I've ever seen.
I really like how this is explained, it feels so much easier to understand than any modern lecture, text, or lesson.
.....
@@yararahman7055 its the truth!
Wow! This is the best explanation of HOW a differential actually works I've ever seen! Every other only really explains WHAT it does, not HOW.
Educational videos like this are timeless! You can show a person who ask how a differential gear works in another 100years and it'll still be just as entertaining and educational.
When you demonstrate it like this it aint boring its *ENTERTAINING*
Yeah if teachers would explain things like this I would love school
This is like... really well explained.
This is the best tutorial I have ever seen... Great job.
I second this opinion
I've seen many, i mean many old videos, they're so informative, i could watch these for hours, they're so good
Pretty sure the guy you're complimenting is dead
It's a difficult explanation to give someone without a mechanical clue... this great film solves the problem. I love "More Spokes"!
That was one long ad. And I'm not even mad!
Gh0sT It was a lesson xD
I like your poetry
how is it an ad? i dont think it said to buy anythen
@@rawtrout007 Not all ads "advertise" in the old methods in this day and age, sometimes they only want you to _think_ about the product the company sells; that's the case of their "free" games!
I need a low center drive now
Notice the classiness here: this was advertising for Chevrolet to be shown in cinemas yet they took more time to thank the group of riders than to harp on about this video being brought to by Chev. They just showed the subtle Chev badge on a wheel cap at the end. The times have changed
я в шоке. сто лет назад сделали такое полноценное видео объясняющее ход мысли инженеров. браво
На ютубе много видео было разработок немецких инженеров тех же годов - но по понятным причинам это всё было удалено. Хотя с точки зрения инженерии очень крутые разработки - эх жаль, если бы не политическая подоплёка можно было бы пересмотреть.
You should check out professor Julius Sumner Miller.... He has a certain way of explaining...
мнe eщё совeтскиe учeбныe фильмы в подобной стилистикe нравится смотрeть
Круто!!!
я только сейчас понял, как работает дифференциал. не то чтобы я тупой, просто раньше не задумывался об этом)))
Bro, why are all the old videos more educational than new ones. All the other explanations i found were too complicated, but this was so easy to understand
For some reason, these old videos are often the absolute best at explaining these concepts. It's the same with science. If I need to fill in some hole in my understanding of high school physics, there's usually one of these old videos explaining the concept much better than anyone else. Like, what happened to education between then and now?!
Now educational videos try to look entertaining and engaging rather than getting straight to the point
Now, they actually don't want you getting smart. A dumb society is much easier to manipulate. Especially now we have smartphones.
Simply amazing. They showed what can be achieved superbly with limited resources in terms of graphic and multimedia. First they explained the problem with motorbike riders and in the end they explained the results with juggling artists.
When life gets hard...... add more spokes.
What a nice thought!! :)
What can be equivalent of more spokes in real-life
Excelent
Spohwkes*.
When life gives you spokes, you make spokenade!
Educational videos back then really hit different, and super effective too.
MORE SPOKES!
I know right he said that like a gumby from monty Python! More spokes!
lmaoooooo my favorite part of the video
MaoTseFunkadelic i thought the same xD
#MoreSpokes
Heard that in Cave Johnsons voice. Brilliant xD
It's really geared toward people who learn at different speeds.
FindaTopDoc Media Well made pun. Like inbound.
I see what you did there. Well done.
As in different learning curves..
nice
Two puns in one. You win the internet twice.
if only the modern School system was this easy and useful.
All it is now is copy this and that into your notebook and take this quiz
Yeah can we just restart back humanity
Not a hint of socialist theory in this video. Therefore, it's immensely better than today's schools.
@@lesterhartness4077 where in school do they teach you “socialist theory?”
@@Leonardo-G For those of us paying attention, it's slipped in there throughout the time a public school student is in school. Only a leftist would deny that the school system has been taken over by leftists, from kindergarten to graduate school. Question,...why don't leftists admit that they're leftists?
Ive seen this video a dozen times and can watch it dozens more. As a mechanically inclined person who does commercial electrical i can really appreciate videos like this. And for thise that dont know electricians, especially us commercial guys, are considered electrical mechanics because we have to build, fabricate, and install mechanical equipment, sometimes complex equipment
