Formula 3

\begin{array}{l} I_{y} = 13, 304 {cm}^{2} \\ z_{m} = 8.786 cm \\ b (z) = 1 cm \\ h = 40 cm \\ d = 45 cm \\ S_{y 1} = b (z) \cdot (h - z_{m} - z) \cdot (\frac{h - z_{m} - z}{2} z) \\ S_{y 2} = b (z) \cdot d \cdot - (z_{m} - b (z)) \\ A_{sz} = \frac{I_{y}^{2}}{\int_{- 30.124}^{8.786} \frac{S_{y 1} (z)^{2}}{b (z)} dz \int_{9.286}^{8.786} \frac{S_{y 2} (z)^{2}}{b (z)} dz} = 30.17 {cm}^{2} \end{array}
