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 5. - 20.4 ksi, 5 – 10.7 ksi, and Sxy 24.0ksi. (a) Determine the principal stresses and the maximum in-plane shear stress acting at the point. (b) On a piece of paper, show these stresses on an appropriate sketch (e.g. see Figure 12.15 or Figure 12.16). For the sketch, calculate the angle between the x axis and the principal stress orientation. Also, calculate ow, the normal stress on planes of maximum in plane shear stress. (c) Compute the absolute maximum shear stress at the point.
(a) a Opl = ksi 0p2 = i ksi Tmax = i ksi (b) 0 = i o avg i ksi (c) Tabs max i ksi
