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.

made in the 30's still better than modern videos

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.

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.

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.

For the year this was made, it really is an excellent piece of film-making. A lot of work and expertise went in to this.

This is so simple and fucking GENIUS.

it's seems to me that the old instructional and howto videos do a better job at explaining things then the videos today

Now I understand how differential works, thanks to this old beautiful video...

This is brilliant. This is how you explain something. If you want more people in STEM, you need teachers like this.

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 wish they would make more videos like this today. Brilliantly concise and so informative.

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.

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 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 just came here after watching this topic on learn engineering. and this is way better. i mean way better.

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..........

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 is actually the BEST TUTORIAL on differential.. great work :)

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!

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.

This is absolutely amazing.

Now we have positive traction w/ clutches, but that's another story 😂

In my aim to learn useful information on a variety of topics (history, tools, technology, techniques, etc.), I come across many videos on KZread 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 understood this video's explanation of a differential more than those animated versions lol

OMG :O Cant believe this video was made in 30s :O . The best clear explanation of differential gear out there (y)

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

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.

I find this absolutely fascinating!

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.

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.
