고체역학 (Gere) — Applications of Plane Stress: Problem 8.5-2

8.5-2 An IPN 320 steel beam is subjected to a point load \(P = 45 \text{ kN}\) and a transverse load \(V = 20 \text{ kN}\) at \(B\). The beam has length \(L = 2 \text{ m}\). (a) Calculate the principal normal stresses and the maximum shear stress on element \(D\) located on the web right below the top flange and near the fixed support. Neglect the weight of the beam. (b) Repeat Part a at centroid \(C\) (see figure). See Table F-2, Appendix F, for beam properties.
