Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 2 ksi in size. (a) Determine the stresses Ox. Oy, and the magnitude of Txy and show them on a stress element. (b) Determine the principal stresses and the magnitude of the maximum in-plane shear stress acting at the point and show these stresses on an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16).
