View Policies Current Attempt in Progress 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 polnt are S-39 MPa, 5,- 17 MPa, and Sy-31 MPa. (a) Determine the principal stresses (opl > o2) and the maximum in-plane shear stress rmax acting at the point. (b) Find the smallest rotation angle 0, (counterdockwise is positive, dockwise is negative) that will rotate to prindpal directions. Then show these stresses in an appropriate sketch (e.g see Figure 12.15 or Figure 1216) Answers: MPa. MPa. MPa Tmax = 0, = Attempts: 0 of1 used Submit Answer Save for LatAr
