Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 11 MPa in size. (a) Determine the stresses o, Oy, and the magnitude of Txyand 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).

Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 11 MPa in size.
(a) Determine the stresses Ox, Oy, and the magnitude of T,xyand 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).
