@@tto4646 So the "cork" makes contact, and frictional forces carry over the rotational movement, which allows the two components to reach the same speed before physically engaging/mating them.

[@ToxicallyMasculinelol]

@@ZandrichMynhardt the reason it's confusing is because they only showed the actual synchronizer in a gearbox rather than showing a visible demonstration of the actual mechanism. so he can understand how the cork works but can't see how the synchronizer is analogous because it's not even visible in their demonstration. the properties and shape of the synchronizer are unclear in the video so you can't really see how it would operate similarly to a cork. the rest of the video is great but they really just glossed over this detail imo

I like that they had to physically make all those models to demonstrate their principles. So much more engaging than a 3D animation for some reason.

[@VintageTechFan]

There is only one thing better than this .. being able to play with such models yourself. I'm an electronics engineer and even today, over 10 years after getting my first degree in it, I always understand new concepts best if I try them out. Especially if I apply them to a real-world problem, even if I had to make one up by myself. But I have to physically do it. I still know a lab engineer from my former university, and he always sees students struggling with things like heterodyne mixing .. until he shows it to them at the lab equipment or his ham radio stuff. Then it clicks into gear ;)

[@FawfulDied]

Depends though. When the mechanisms get complex an animation gets much better since you can make parts partially transparent, to focus on an important part without losing the big picture.

@@SLUGTHUG 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.

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

This is so critical, but today people will just say "transmissions work because of gear ratios." Ok, but what are gear ratios? Why is it easier for a smaller gear to spin a larger gear with more force (but slower) and harder for a larger gear to spin a smaller gear (but faster)? Because of leverage. Of course, nobody actually knows what leverage really is, but this is much closer to an actual explanation of how gears work than today's.

Between 1936 and 1990, the method of editing films changed very little. Then in the early 90s a video copy could be used to edit, but the negative still needed to be cut by hand. It is only in the last decade that digital cinema projection has been introduced and the whole editing process is carried out on video.

Can we take a moment to appreciate the filmmaking here. This film from long before computers and digital photography… has fade and wipe transitions, animation overlays, pop up text, and perfectly synchronized voiceover. Now any kid with a computer or smartphone can do this stuff without even thinking and shoot, edit and distribute videos in minutes. But in the 30s you needed education in filmmaking, training on various kinds of equipment and workshops, and a whole lot of time to make edits physically on film frame by frame.

[@thomaswarren2699]

Wow. I had never thought of gears as a collection of levers and fulcrums. That's blown my tiny mind.

Because its simple, now they come up with all that vocabulary BS, basically, you have to find how you like to learn things, me personally, I prefer the dummy way, then bring vocab after I get how it works, for example, this thingy works with this thing to make this other one spin, not some stupid shit like this first gear is giving an input of 3:1 gear ratio to this other gear, so this other gear outputs a greater total speed, but that's just me some people like to read a book on how it works, others like to see an example and see it work, so just figure out how you like to learn and either look for videos like that or some how translate it to your "language"

[@deluxeassortment]

Well, to be honest, modern transmissions are far more complicated and it's difficult to follow the flow of power. I actually always find it easier to start with the earliest prototypes of machinery and follow the progression of improvement over time. We're in a good position to understand CVTs right now because they are still relatively simple. We have only gone from opposing cones to the current squeezing pulleys, so there's not much to them just yet. They will get more and more complicated over time, and those of us keeping up with the current design changes will be able to understand them much more thoroughly.

[@johna9994]

[@Dhalin]

Well to be fair, today's shifters, clutches, and gearsets are WAY more complex than the ones shown in this video. And this video does not mention how a modern clutch works. When you push the clutch pedal in, you are entirely disconnecting the engine from the transmission, re-aligning the gears (shifting) and then re-connecting the engine with the transmission. This isn't how shifting works in the transmissions featured in this video, because the engines at the time didn't run at 3, 4, 5k+ RPM like today's engines do.
