Question
Mohr’s circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 360 psi in size.
(a) Determine the stresses σx, σy, and the magnitude of τxy 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).
