Question

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 = 17 ksi, Sy = 11 ksi, and Sxy = 17 ksi. (a) Draw Mohr’s circle for this state of stress. (b) Determine the principal stresses (σp1>σp2) and the maximum in-plane shear stress τmax acting at the point. (c) Find the smallest rotation angle θp (counterclockwise is positive, clockwise is negative) that will rotate to principal directions. Then show these stresses in an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16)
