고체역학 (Beer) — Principal Stresses Under a Given Loading: Problem 8.14

8.9 through 8.14 Each of the following problems refers to a rolled-steel shape selected in a problem of Chap. 5 to support a given loading at a minimal cost while satisfying the requirement \(\sigma_m \le \sigma_{\text{all}}\). For the selected design, determine (a) the actual value of \(\sigma_m\) in the beam, (b) the maximum value of the principal stress \(\sigma_{\text{max}}\) at the junction of a flange and the web. 8.14 Loading of Prob. 5.78 and selected S310 \(\times\) 47.3 shape.
