WebJun 28, 2024 · The result is equation 3 below, which is the same as equation 2. If you want to find the stress tensor after rotating your coordinate system counter-clockwise by 30 degrees, you can simply use equation 3, which should give you the result below. Finding the principal stresses will require us to find the angle at which the shear stress is zero.
