Mohr's Circle PRINCIPAL STRESSES in 2 Minutes!

[@LessBoringLectures]

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

[@emirhanartik5573]

First, thanks for the video. I could not understand how we found principal stress. Can you explain a little bit, please?

[@LessBoringLectures]

We find the center, and then we add and subtract the radius. The explanation of why we do that is here: kzbin.info/www/bejne/l6bQf2CMoZWCnrM

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?

[@kemperhp4732]

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

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

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?
