Cross section of a short reinforced concrete column is shown below. Considering interaction between axial compression load and bending moment, determine the factored moment resistance \( \left(M_{r}\right) \) of the column associated with point (1) on the interaction diagram. Note: Point (1), corresponds to the pure bending condition \( \left(P_{r}=0\right) \). Given: - \( f_{c}^{\prime}=25 \mathrm{MPa} \) - \( f_{y}=400 \mathrm{MPa} \)
