I wish this video was available in 1975, in my junior year of ChemE. I first saw this in Transport Phenomena I, in Bird Stewart and Lightfoot. Was totally dazed and confused. Barely got a C in that course. Finally, 45 years later, I understand. Too bad I've retired; though better late than never - at least I can die in peace. Thanks so much
Ha, ha. Yes, I am in the same position. I used to think I was not very smart as i could not understand many of my text books nor the professor trying to teach the material. I am having fun learning this material and finally understanding it. (Where was the internet when we went to college?)
@@MichelvanBiezen Thanks for your high-quality and succinct tutorial. I'm afraid that's usually the case for us to get to understand new things as you said. The solution lies often in time, repetition, and patience. When my professor taught me the Cauchy stress tensor for the first time, I was confused totally. At that time, I used my middle school knowledge to accept it this way, that the force can be splitted equivalently onto the 3 axes, and stress is just force per unit area.
@@allanwei9709Chemical Engineers don’t only learn about chemistry, they also have to learn about transport process in the chemical plants(reactors). There they will need to use and learn Fluid dynamics and stress tensors. This will more to the branch of process engineering I guess.
I think top-right component should be Tau_xz and not Tau_xy? Pointing it out in case of someone who's fresh to the topic would become confused. Anyway, best channel on UA-cam. Thank you as always sir.
Sir plz teach us QM too...i have lots of doubts and there is no such a channel as like your...plz could u make some videos on hydrogen atom and some examples on it...this will be very help ful for me...thnx for this video
Sir I pursuing mechanical engg and I came to know this concept in strength of material subject,. why does we considere the cube element for stress analysis and what does it mean that on x plane we have three stress i.e sigmax , touxy , touxz , and similarly on other plane also .please reply sir

You were taught tensor in chemical engineering? How?

Yes, it should be Tau_xz
Yes sir
Sir, you are the best physics teacher I have had. I will always be grateful for your lectures.
The best teacher I have ever seen! Thanks Sir! God bless.
Thanks a million of set of lectures on Tensors. Crystal clear again.
You're very welcome!
Cannot explain in words, how helpful your lecture is to me to understand the concept pf tensor. Thank you so much sir !!!🙌🙏
Glad it was helpful. 🙂
So now its clear what a tensor is :) Thank you for such an amazing explanation Mr. Biezen.
You are welcome. Glad you found our videos. 🙂
A real hero ❤
glad you like our videos.
Excellent video showing a practical example. Thank you.
Glad it was helpful!
You explain this topic so clearly! ❤
Glad you think so! 🙂
The stress and shear notations really help thank you
brilliantly explained tensors thanks a lot sir!
Glad it was helpful!

We are planning on tackling that topic next.

Wow, great video!
Thanks!
Hi Michel I think you have made a minor mistake in that the second component of your subscript for tau in position 1,3 should be "z" rather than "y".
Sir, will you cover the differentiation of tensors or not ?
Eventually. Working on the more basic concepts first.
Sir, I think , there is a mistake.
In the first row the third element should be xz. Both of them cannot be xy.
Yes, you are correct
@@MichelvanBiezen Sir do you have any lecture explaining the Metric Tensor?
Very intuitive, thanks a lot!
thank u sir you helped my discussion
Thank you very much
