    The transmission in the modern motorcar -- the mechanism that makes it possible to have three forward speeds and a reverse -- is a series of levers, levers that spin.

I wonder if these guys knew in 1936 that over the next 100 years, no one would beat them in their explanation of how a manual transmission works.

BULLSHIT! They taught you how a manual transmission works except for the fact that they left out the clutch, the clutch plates, the clutch pedal, the differential, the reverse gear, the universal joint, the shift lever and the shift linking mechanisms. It seems easy to understand because it actually taught you almost nothing - esp about how a manual transmission works. You learned only this: 1. Gear turn. 2. Gear is like a round lever. That is it. Pretty impressive! /s

While I enjoyed the view of the corporate secret by a fellow commenter and absolutely agree, back then people didn't have the internet and such a programming would obtain good dollar for this video, so they explain meticulously and put effort in making sure we understand and leave nothing to assume they got it. Like now alot of people would assume you know certain things like what is a gear but back then people hearing what a gear was, well it must have been mind blowing.

I'm starting to realise that I think the reason these old videos are so effective is that they explain everything simply from the ground up for people that wouldn't have had any idea what they were talking about unless they did. The transition from levers > lots of levers > gears/cogs makes a lot of sense and wasn't really a connection I made before today - I just knew the principle behind changing the gear sizes to get more or less power.

@Commissary Good point. Fixed it! No. It is that the concept being taught is simple and can be demonstrated with a simplistic physical model. Models can only teach subjects that are ridiculously simple. Any subject with even a minimal level of complexity, which is about everything nowadays, can not be taught using physical models. The reason this video seems easy to understand is not that the creators of the vid possess underappreciated genius as enlightened renaissance men, it is because the subject matter is basic enough to be understood by relatively stupid people. Just like a baby with zero ability for abstract thought has no problem sticking the round peg into the circle hole. Every person who is on about 'how wonderful of a presentation that was!" is just outing themselves as too lazy to make the effort to understand anything more complex than a 1920s gear shift that has the clutch, clutch plates, clutch pedal, differential, reverse gear, universal joint, shift lever and it's linking mechanisms removed to dumb it down. It seems easy to understand because it actually taught you almost nothing about how a manual transmission works. You learned only this: Gear turn. Gear is like a round lever. that is it. You are so impressed with yourself for learning that, that there are thousands of you bragging about it in the comments. How are you not ashamed of yourself for taking until now to figure out "gears be like spinning levers"? Educational standards in this country have gone way downhill. We Americans truly are #1 at being fat, lazy and stupid.

@Jason Bender Proof read what you wrote. Your grammar is all over the shop. Take the first paragraph for instance. That being said I get the gist of what you are saying. You are definitely wrong. Transmissions are complex things, they’ve really just put a basic or stupid model (as you so eloquently put it) so you can grasp the idea. Same thing could be done with any technology we have now. Stop being petty.

I feel like I actually became smarter from this, and that's coming from someone who's easily confused by too much moving stuff at once. This is really clever, both how it all works, and the way it's all explained. I very much appreciate how clearly it's all broken down and explained, and I feel like this is probably the closest I'll understand how on Earth a transmission works. I also never really thought about gears being levers before. It's amazing how people come up with this stuff, how it came to be. People were geniuses in the day, man. I feel a little smarter from the video, but also dumber at the same time, wondering how the hell people invented transmissions.

It's odd because you would think the older film would appeal less to younger audiences, but the reverse is true. I think because in these older PSAs, there's some actual filmmaking expertise at work. The shot at 2:00 for example, you'd never see something like that in a modern PSA. These aren't just educational, they're shot and edited well and are just fun to watch.

I think what makes this video so easy to understand and pertinent even to today is the fact that concepts are explained. We all know of the sinple machines and the lever being one is employed in our daily life. As complicated as a modern transmission is, breaking it down to simple levers of varying sizes and fulcrum points is almost mind blowing

@EnjoyCocaColaLight That answers your question. To explain a bit more: A problem was that before synchromeshes were introduced, it was difficult to engage 2nd gear going downhill. The driver had to press the clutch to change to neutral, release the clutch, rev the engine to the speed it would be turning if the gearbox was in 2nd gear to speed up the input shaft to the gearbox to the required speed, then press the clutch again and change to 2nd gear. This process, known as double declutching, was difficult (you needed to listen to the actual engine speed, know the required speed, and adjust it to match) and was the sort of thing people talked about back in those days. A major problem was that most people couldn't do it. This film was basically saying "Look, we've added synchromeshes to the gears, so now there's no excuse for not using 2nd gear going downhill (even a blonde can do it), and therefore no excuse for crashing".

Hace 6 días
JB +1
JB

@EnjoyCocaColaLight On long steep hills, the brakes (drum brakes on all four wheels) weren't good enough by themselves. They would overheat then become ineffective (fade) i.e. they wouldn't stop the vehicle however hard the driver pressed the brake pedal. Crashes therefore resulted. Changing to a low gear (e.g. 2nd at up to 40 mph and 3rd between 40 mph and 70 mph) on hills solved this problem. The torque required to turn the engine (say 50 Nm) was multipled by the gearbox ratio (say 2.5:1 for 2nd gear) and the differential ratio (say 3:1) giving a lot of wheel braking (375 Nm in this case - or around 1250 N = 125 kgf). This braking is known as engine braking. The brakes only had to provide the remaining braking torque required and therefore didn't overheat and therefore didn't fade. And therefore didn't result in a crash. All this assumes a manual (non-automatic) gearbox, like the one in the film.

Actually, I think that was the WHOLE POINT of the film!! On the surface it teaches how a gearbox works but is actually I reckon a cover for saying, "even a young blonde can avoid crashing into others by managing to get her car into second gear when going down a steep hill - SO YOU CAN TOO". The generation before me was from the era, and I remember a lot of talk - even at parties - about gear changing, stripped gears, and how to get into low gears so you don't cause crashes, with the poor (artificial) blonde being the "lever" used to try to get everyone to up their gear changing game!

Great stuff!!!! We still use the same method today but the complexity has increased a hundred fold. In the 1960s an Apprentice became a motor mechanic after 4 years and he knew how to fix EVERYTHING on your car. But with today's automobiles you need a specialist mechanic for the motor, the gears, the exhaust, the electrics and electronics, etc., etc. No single mechanic can fix everything on a modern car.

I love the explanation. It is sad to see that a lot of explanation videos are made to highlight the teacher rather than the content. The teacher, in order to come across as intelligent, uses a lot of jargon. It also works because a lot of comments under those videos praise how cool or smart the teacher is. The real teacher who cares about the learner gets out of the way of the explanation as much as possible and lets the content to shine.

What a pleasant learning video. Well produced, to the point and memorable. This simplicity really needs to be brought back. Lucky for us, they didn't have any available computers, or we wouldnt see the simple mechanisms purpose built for demonstrations. They also didnt have casting issues, where someone was complaining about not being fairly represented; it focused on the workings of the transmission first and foremost. I cant tell you who was in it, or how many people they showed, but I can now explain how a transmission works!

@Engineer I know thats basically a joke about my user/channel name, but I will explain anyway: I just like them, and they are getting rarer and rarer since almost everyone is moving to electric. There are only a few manufactures left out of the dozens there once where. "Large" scale I can only think of OS and Saito being left, both of them continually reducing their "nitro" portfolio and moving to petrol engines. Enya and Laser are still doing limited production runs for enthusiasts. Also there is Yamada with the high performance four-strokes. The whole complex of Magnum, ASP, SC and all the manufactures "house brands", which were all made by Sanye in China, is gone. But it's nowhere near the volume they once where, and I like them. So I grab them as long as I still can. The old ones from the 70s-90s tend to be of better manufacturing quality, too.

They were probably either rotoscoped in or double-exposed with frame-by-frame animation. In both case this is very labor-intensive, as it required manually altering and splicing as many film frames as there are seconds elapsed times 24.

yup. a (larger) wheel/gear driven by a smaller one is a (continuous) rotary Lever !!! the larger the radius of the driven wheel THE BETTER. because the result is MA that is Inherent, in a 'larger-radius' wheel. MA is mechanical advantage; lever arm. (these are some of the reasons why the radii of wind turbine rotors Never get smaller.) it can be SEEN that it is Simple/easy to convert reduction-MA to Inherent MA. this is the WELL-understood principle of converting 'high rotation rate to torque'. thanks to some ancient dude, humans have developed a GIANT blindspot, regarding the existence of a transient/intermediate, potential energy GAIN in the transform. if interested, see my research. cheers googletranslate

I've watched this video about 4 times now, and I can't seem to wrap my head around that speed cork-in-bottle clutch thing. I wish they dived a bit deeper in how it worked. Besides that, I love this explanation so much.

Clutches are considered disposable and a part expected to wear out because they operate using friction. The other comment is a good explanation of how it works but I thought it prudent to add this to it. A clutch is basically a part designed to wear out over time sitting between two parts you should never have to replace. When people speak of "burning up" a clutch they're talking about it wearing prematurely. Usually as the result of an operator that rests his foot on the clutch pedal at all times. Thus causing the clutch to be partially engaged at all times. Since constant friction is a great source of generating heat it isn't long before all you're left with is a funny smell and no more clutch material. Cork is a good example material. Rubber or any other soft material would also be a good example of explaining how the clutch works. Think about it like this. Imagine you have a gear made of something soft like cork. It connects two other gears made of a harder material like metal. It is partially engaging both metal gears and sacrificing itself anytime the two metal gears are not in sync. When engaged it's always between the two metal gears and when disengaged it's tucked somewhere out of the way and not involved in delivering power at all. Hence the video's "cork in a bottle neck" example. Our cork gear can freely slide between and out of the way of our 2 metal gears whenever we want. We can control how much or little it's engaging with the metal gears. Let's suppose your two metal gears are not in sync. Gear #1 is spinning at 8,000rpm while Gear #2 is spinning at 2,000rpm. You want to match the speed between both metal gears before attempting to fully engage them. We can not force them together because they're too far out of sync. If there was no clutch you'd be forced to slow Gear #1 down to 2,000rpm before engaging with Gear #2. With the clutch we get another option: We can slowly bring the speed of Gear #2 up to 8,000rpm through partial engagement via the cork's friction. A little bit of cork will be sacrificed and lost to friction every time we do it. Once Gear #1 and Gear #2 are both spinning at 8,000rpm our cork gear is disengaged. It gets out of the way of the two metal gears allowing them to fully mesh up and spin at the same rpm. Our soft cork gear is tucked somewhere out of the way until it's needed again. Giving it a chance to cool down and saving the precious soft material for the next time our metal gears are out of sync with each other. Or if we feel the need to do other fun things like engine braking or upsetting the balance so we can deliver tofu faster. Also I should point out that those rpm numbers are just examples. IRL what would happen is Gear #1 would drop from 8,000rpm to about 6,000rpm while Gear #2 was coming up to speed. When both gears were at about 6,000rpm they would engage with each other because they were now in sync. Gear #1 is being robbed of power by the clutch's friction and bring Gear #2 up to speed. Gear #2 would be spinning freely in this example and not generating any power on it's own. At any rate both gears would meet somewhere in the middle, sync/engage then the clutch would get out of the way. "Floating" gears is simply matching engine speed to wheel speed (Gear #1 to Gear #2) and engaging the gears together without use of a clutch. In a lot of professional driving jobs (racing and trucking) the clutch is only really used for starting from a stand still. It's easier and faster to match engine and wheel speed manually. The smoothest possible/optimal shift point is always when both of these things are in sync. There are other benefits as well. Left foot braking for example. Just think of the clutch as an oddly shaped gear made out of softer material than all the others. I feel like I've rambled on too much. If you still don't understand it and I suggest learning how motorcycle/ATV/small engine transmissions work. They are easier to wrap your mind around than automotive transmissions.

It's the increasing friction due to the cone shape of the cork. When you just barely put the cork into the bottle, it very easily spins because there is little friction between it and the neck of the bottle. When you start putting the cork deeper inside, you're going down that cone shape and increasing the diameter of the cork that touches the neck of the bottle. In essence, you're reducing the air gap between the surface of the cork and the neck of the bottle and by doing so, you're increasing the friction. You do this until the friction is so high that you can't freely move the cork. The same thing happens with the synchromesh mechanism. You can see the synchronizer at 7:40 also has a cone shape, the circumference of the left side is bigger than the circumference of the right side. Initially the 2 gears/shafts are spinning at different rates but when you move the synchronizer from one gear into the other gear, you are gradually pushing that cone into a tighter gap and increasing the friction between them, until the friction is high enough that they are basically "locked" together and spinning at the same rate. This gradual increase in friction is what lets you change the gears more smoothly.

@W33d Senpai went on a road trip with family through the Canadian Rockies in a minivan loaded with stuff recently. Driving up a hill is like "power please... Really could use some power... I'm twenty under the limit now please downshift! Seriously van? Where the fu- WOAH okay that's a double downshift, maybe don't spin the engine at 5k rpm you can cool it. Are you gonna use fifth or is it no power in sixth or mom getting pissed off for revving out her van in 4th?" It's exhausting. I hated driving that thing.
