You are looking for the orientation where the stresses are in their principle state (no shear). If all three of the axis (signma_xx, sigma_yy, sigma_zz) have a stress there will be shear present and are not in principle state. The left and right axis indicate tension (right) /compression (left). If the circle is solely to the right of the axis it is Case 1 which is Tension-Tension
This is one of the vest lectures I have seen on this topic. It's quite fast. He also gives a recommendation to watch the previous one - are you sure it isn't your fault for not understanding?
CORRECTION: I wrote down the principal stresses where the maximum overall shearing stress goes and vice versa. Spoken information is correct, though.
Whew~ glad I read this comment. Thanks for clarification
First, thanks for the video. I could not understand how we found principal stress. Can you explain a little bit, please?
We find the center, and then we add and subtract the radius. The explanation of why we do that is here: ruclips.net/video/aumN-Vl0OhQ/видео.html
wow, rally amazing
Why do we just have sigma z to be 0? Do you do that for all problems or only where the circle is to the right of the shear stress axis?

great video
Thanks!
randi video
Very very very third class lecture. Try to make understand your students first. It’s not story to read aloud only. Just hilarious lecture 😡
Yes, like a high speed train, how can others understand
