Example 2
The beam is subjected to bending and axial tension/compression. Draw the diagrams of normal forces and bending moments. In the most loaded section, draw the diagrams of normal stresses along the height of the section from: - tension/compression, - bending, - the sum of the two preceding ones. The geometric characteristics of the sections are given: IPE200 \begin{aligned} &I_{y 1}=29.3 \mathrm{~cm}^{4} \\ &A_{1}=13.5 \mathrm{~cm}^{2} \\ &b=10 \mathrm{~cm} \\ &h=20 \mathrm{~cm} \end{aligned} C100 \begin{aligned} &I_{y 2}=1940 \mathrm{~cm}^{4} \\ &A_{2}=28.5 \mathrm{~cm}^{2} \\ &e=1.55 \mathrm{~cm} \\ &b=10 \mathrm{~cm} \\ &h=5 \mathrm{~cm} \end{aligned}
