After all this time, I just got it. The problem with not getting it is how it is explained. A vector is not explained like it has anything related to the surface of something. It is typically explained as direction with respect to two direction in the sense of motion as in something moving, i.e. velocity. Tensor should not get mixed up with vector at all. Why? Because when most people hear vector, in their mind they think about something moving. Tensor is stress on a surface. Force directed to the surface, or directed with respect to its two other components. width, length so to speak.
A tensor is a linear application, we can represent a tensor as a scalar, a vector and a matrix, but a vector is not a tensor, it could be the representation of a tensor but never a vector. However a tensor of first order id bijective to a vector. Anyway, a good video though.
In this video, I have assumed the vector in the upward z-direction to be positive. Because whenever we consider a 3D space in Cartesian coordinate system, the z is positive in the upward direction. So I took upward z-direction to be positive.
Thank you Anirban. I will try to make a video on elastic constants but it may take some time as I am currently working on a video about a concept from thermodynamics, i.e. 'Entropy'. You can subscribe my channel and press the bell icon to get an update when I upload a video about elastic constants.
Really a informative video.....best explanation.....I suggest promote your few videos so that you will get worldwide subscribers.... Becoz your videos are of international form.....fantastic keep it up
Excellent vedioo
Thanks for the appreciation

Short and sweet and great explaination
I am glad you liked the explanation😀
Thanks so much. it was clear!!
Glad you liked the video
Nice video 👍
Perfect explanation
Glad you liked it. Do watch my other videos if they are relevant to you and share with your friends.
@@ENGINEERINGSTREAMLINED sure👍
Nice
Thank you very much. Do watch and comment on my other videos
Very good video
Thanks

@@keydi98 Thanks
Super nice explanation I understood here greater than in class
Thank you very much for the appreciation. Do watch the other videos if they are relevant to you.
Nice explanation
Thanks and welcome
Very nice explanation
Thanks
This is an excellent video. Well done. It definitely helped me understand the concept :D
Thank you for the appreciation. I am glad it was helpful for you.
What means of sympol hat indicates to
The symbol hat is used to represent unit vectors. Means their magnitude is one.
@@ENGINEERINGSTREAMLINED aha u could replace it by iust i,j,k .true??
@@hawraaraheem2449 Yes, you can write them as i, j and k
@@ENGINEERINGSTREAMLINED thank you alot
N.B.!!, here: Y x X = +Z , and X x Y = -Z
Tensor is a matrix of vectors
Yes you can say that. Basically a way of representation of vectors.
In what program you made this video?
I made all the animations in Microsoft Powerpoint and edited the video in Olive Software (Free software)
You don't explain what's the meaning of why we have 2 unit vectors ??what's the reason for that and how it's come 2 ?
Which time frame in the video are you referring to?
sehr gut
Danke🙂
sir can you pls explain how can be positive direction of z is upwards it should be downwards na????
In this video, I have assumed the vector in the upward z-direction to be positive. Because whenever we consider a 3D space in Cartesian coordinate system, the z is positive in the upward direction. So I took upward z-direction to be positive.
Plz, make a video on physical importance of Stiffness matrix in simultaneous differential equations of solid mechanics. 🙏
I will try to make the video.
very nice and simple explanation. very good sir. can u make a video on "elastic constants ( C11, C12 etc.)"?

Thank you Irfan for your kind words. Comments like this inspires and motivates me to make more videos.
thank yoy very much

What is sanctions meeting
.
I didn't understand your question? Is this related to this video?
Vector is a mania of HAMILTON and the Tenor is the MELANCHOLIA of ALBERT EINSTEIN. Tensor √√√, tenor ×××
Too quiet
nice explanation
