I know that this is the final result, I would just like to be able to prove it. I drew τ2 and τ4 in the wrong directions intentionally because it is not obvious to me why the complementary stress relationship is valid in cases where normal stress is present. I suppose what I am looking for is a...
Homework Statement
My textbook says that the state of plane stress at a point is uniquely represented by two normal stress components and one shear stress component acting on an element that has a specific orientation at the point. Also, the complementary property of shear says that all four...

Hello,
I’m a freshman engineering student at CU Boulder and I'm currently majoring in mechanical engineering, but I am seriously considering making the switch to aerospace engineering. I had a 4.0 GPA for the fall semester, but obviously that is not with very difficult classes (calculus...
