I understood the basic concept of a U-joint, but had no idea that the output speed wasn't constant. Very interesting. Thanks for the video!

Universal joint: I'm complicated Automatic transmission: Hold my planetary gearset

this video turned a simple concept into a total mind fuck........thanks :D

"Now you understand how an universal joint works. Thank you." No. Thank YOU!! :oD

Upping my Lego mindstorms game

One thing that should be noted in the last example (double U joint): The input and output shaft have to be parallel for the velocity to remain constant.

This has absolutely NOTHING to do with my education but I still watched the whole thing xP

Now I understand how offroad vehicles can flex so much, thank you!

Another superb explanation...You made Understanding Mechanical really easier.

The video is exactly what I needed. He didnt just explain the parts and purpose of the U join, like most other videos, but he also talked about the physics

This is simply brilliant. Really explains the non-constant velocity perfectly.

You missed one very important point! The angle of the outputting universal joint must match the angle of the inputting joint. This problem was the source of some vibration concerns with some RWD vehicles and I have seen quite a few "Raise Kits" put on the rear suspensions of cars and trucks that did not take this into consideration. Some of those vehicles shook so violently they would loosen the fillings in your teeth! The concept of the constant velocity joint was used in the 60's and well into the 80's with what was called the "Cardigan Joint' and it had a very short piece of shaft at the front of a lot of driveshafts on GM RWD cars. A bit more complicated than this video showed, it served pretty well to eliminate vibrations caused by angle variations as long as the final output angle to the differential was under 1 degree.

Thank you, I had no idea about the fluctuation in speed etc, especially the last minute was very helpful!

3:21 you may have outsmarted me but I outsmarted your outsmarted

You've just make my understanding of the world more complicated.

INCREDIBLY interesting and informative!

I needed this video in my life.

This video has made a huge difference to my understanding of this joint! Along with helping me complete my course work, many thanks.

This is great, thank you for teaching me for free, you deserve more subscribers

Thank you very much. Effort much appreciated.

Thanks for the interactive animation and explanation !

what an amazing explanation. hope we can learn more things from you guys.

Such an excellent video I have ever encountered with! It is explained with simple graphs and simple explanations, as well as supported with a simple video, I really enjoyed it, and I am so grateful :)

Excellent video. This is why when reassembling a tail shaft, it is very important that the marks on the slip joint line up, so the angles on each end also match

Wonderful animation! Made the concept clear as day!

Thanks so much for posting! This is a concept that I think very few professing professionals even have a clue!

Awesome work. Please continue the job.

I loved these videos. Thank you for this video uploader! 🤗

keep it amazing man, your voice makes me know I'm about to get better

Your explanation were so clear. Awesome dude!!!

Dunno why this was in my feed, but, I'm impressed by it.

Wonderful! Thank you from Texas!

Great video!!! Congratulations, It now I can understand how a universal joint works

Now I have understood U-joint in a better way. Thank you for making such a video.

Nice video, especially after smokin some good universal joints 🤙

Wow. Never thought that mathematical abstractions could solve mechanical challenges with such ease. Thanks for sharing.

Thanks, this is amazing....

I clearly understand about universal joint. Thank you

THANK YOU VERY MUCH! i feel much better having understood this

Awesome 👍👍 its so easy to understand. I'm glad i opened youtube to find out. And I'm logging without any other video 😁

Thanks that was well explained. Good work.

Thanks so much for such an interesting vid!

Very useful for my final exam, Thanks!

This video showed up randomly in my recommendations. No regrets at all :D

Great video. Learned something today. Thanks

Thanks for the video! Really helpful :)

It seems like everybody is here because they were curious. Not because they actually needed to know. And I think that is great.

Amazing animation with lovely explanation :)

Excellent video...thanks for sharing.

this is f-ing amazing. Thank you

Don't know why I needed to know this but I now feel empowered.

Thanks for amazing explanation

I have always wondered how that works... omg thank you

If you look at light-duty 4x4 trucks from decades ago (50s, 60s, and early 70s), the transfer case was tilted down toward the rear to reduce the angle of the U-joints in the rear drive shaft (the shaft with the greatest need for running efficiently), but this increased the angle of the U-joint on the front side of the transfer case. To accommodate that, they tilted the rear (input side) of the front axle downward. This rotation of the axle position away from the position that "looks right" increased the angle of the U-joint at that location so it was a close match to the steep angle of the U-joint at the front of the transfer case. It's a setup that looks very strange if you don't know the reason, and this video explains the reason.

outstandable!!!!!!!!Thanks Learn Engineering

Thanks for your support

Very informative and easy understanding

please keep thermal related videos....your animations are simply superb....

Great explanation!

Thank you. I am trying to build a Lego articulated suspension system with steering. You have helped me understand the universal joints.

awesomely explained

Really awesome! Congratulation!

It is clear that this video helped me alot

Thanks RU-vid for allowing me to nerd out when I least expect it.

I love that this is recommended to me

excellent explanation...thank you very much.......

I've been searching for this for over a year and now finally I know how a fwd is able to steer while powering the wheels

Excellent information.

Finally my curiosity has been answered, nice animation

I needed to figure out a way to transmit rotation to another axis without bevel gears and I had no idea how great universal joints were until this video. Thank you so much! You fucking rock!

Ooooooo my gosh ....... Never knew that the speed on the output shaft isn’t constant after changing the angle 🤷🏻‍♂️ Thanks a lot dear for uploading this informative video 😊

Very clear and interesting

very well explained

Loved this video. thanks

nice.. helpful for theory of machines

That was interesting, thank you

Your welcome, for teaching me stuff.

Why am i watching this at 2 am Either way, that was some good narration and good explanation, thank you

excellent explanation!!!

Ur explanation is suprb

Very clear explainantion!

Great job. I am a Uni joint manufacturer but never knew why do people use double joints.

In one word : Great!

Great lesson

My teacher always told us to use two for balance. I sorta imagined it was something like this but this is a nice video!

Thank you . I love mechanism

This was amazing

Still bends my mind

Thank you i understood a lot

thank u so much now I am understand how work universal joint✌✌✌✌

concise and clear!

this is very helpful

I was wondering this exact thing just yesterday

Great job.

Thanks for this video love from India

In your channel all videos are good Fentastic animation

Thank you very much good sir 👏👏

Excellent video..
