(b) A two shear walls are subjected to homogenous plane stress state with 1) x=100 N/mm, y=20 N/mm and Txy=60 N/mm. 2) x=0 N/mm, y=0 N/mm and Txy=10 N/mm. Sketch Mohr's circle for the given stress state, determine the magnitude of the principal stresses and the direction of the major principal stress relative to x plane. Calculate shear stress at plane 45 clockwise from plane where is x plane acts.
