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 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.
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.
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.
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
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.
Almost got it. actually , more students equates to more funding. Absolutely nothing to do with learning and even less to do with understanding anything.
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 RU-vid, they have a lot of similar films.
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.
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 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.
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.
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!
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.
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'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!
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.
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!
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.
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.
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.
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..........
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.
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.
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.
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.
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.
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.
