- I am struggling to understand the concept of Principle Stress plane.
All the materials that I have been reading, it says that when the element is rotated to a θ, this will be called the principle stress plane with no shear force acting on it. but visually when you rotate the element, there will be a shear force acting parallel to the plane. I am very confused, can someone help me, please? Do we have to assume that at some θ, there will be no shear force acting?
