Can you please help me with 2.4. Thank you

Transcribed Image 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.
