PRINCIPAL STRESS Using the same method, derive principal stress formulas for the other two quadrants (second and fourth).
IN-PLANE SHEAR STRESS
Using the same method, derive in-plane shear stress formulas for the other two quadrants (second and fourth).
The result is supposed to be the same equations derived for the other quadrants (photos shared). The only possible difference is the change in sign.
