Maximum shear stress in Mohr's circle

[fonseh]

By any chance, are you familiar with dyadic tensor notation?

i haven't learn this before

I'm trying to think of another way, but have not been successful yet? Are you saying that you could not multiply a 2x2 matrix by a 2X1 column vector? By any chance, are you familiar with dyadic tensor notation?

Not having the most appropriate mathematical tools to analyze this stuff makes it much more difficult to learn. It's like trying to do mechanics without knowing calculus.

perhaps you can try yo help me on this thread first , https://www.physicsforums.com/threads/angle-of-principal-stress-vs-maximum-shear-stress.897353/

I think this is more easy compared to the question in this thread...
