N.B. It is unlikely that the Tresca theory will give such a high value in practice since the axial working stress (ignored in this calculation) may well become the major principal stress o\ in the working condition and increase the magnitude of the denominator to reduce the resulting value of n.

Problems

3.1 (A/B). Determine the shape factors for the beam cross-sections shown in Fig. 3.45, in the case of section (c) treating the section both with and without the dotted area. [1.23, 1.81, 1.92, 1.82.]
