A typical cross-section of a reinforced concrete beam is shown in the figure below. Consider an effective depth of $$830\mathrm{mm}$$. The concrete and steel material properties are given below. a) Calculate the factored moment resistance for the beam section. b) Check whether the amount of tension reinforcement meets the CSA A23.3 requirements. Given: $$\begin{array}{rl}{f}_{c^{?}}^{?}& =30\mathrm{MPa}\\ f_y& =400\mathrm{MPa}\\ {?}_{c^{?}}& =0.65\\ {?}_s& =0.85\end{array}$$
