Sigma x and Sigma y are the given stresses, not the principal stresses. Different combinations of given positive and negative stresses--together with the shearing stress--can result in a) two positive principal stresses, b) two negative principal stresses, and c) one positive and one negative principal stress:

I love your videos. Thank you! Been out of the University for a couple of years and these videos helped me a lot to get up to date

[@user-sn8fu7vu6f]

Love your courses! Thank you for bringing these much easier lessons to learn mechanical engineering design!

[@vilivont4436]

Best explanations, i wish you much more followers

[@lamtran2993]

More less boring lectures of mechanical design, please 💙❤

[@LessBoringLectures]

I'll be adding some to the current 39 main ones in a about a month.

[@prakritreeeeeee]

Thank you so much, love your videos. 🙏
