Extracted text: 2. Assume the plane stress state: 01 = 50, 02 = -250, 112 = 150 (all stresses in MPa). 2.1. Sketch Mohr's circle for this stress state. 2.2. Using Mohr's circle as a geometric guide, determine the principal stresses and the direction 0p1 (+CCW from i, axis). 2.3. Again, using the circle as a geometric guide, find the maximum shear stress (+Tmax) and the orientation of the axes (from axis i¡) on which it acts. 2.4. Find o,* and 112* for an axis system with i," aligned 45° (+CCW) from ī.
