Consider a point in a structural member that is subjected to
plane stress. Normal and shear stress magnitudes acting on
horizontal and vertical planes at the point are Sx = 30 MPa, Sy =
56 MPa, and Sxy = 26 MPa. (a) Draw Mohr’s circle for this state of
stress. (b) Determine the principal stresses and the maximum
in-plane shear stress acting at the point. (c) Show these stresses
on an appropriate sketch (e.g., see Fig. 12.15 or Fig. 12.16). (d)
Determine the absolute maximum shear stress at the point.
