Determine the moment capacity of the uncracked section of a cantilever beam shown in the figure, for a concrete compressive strength \(f'_c = 35\ \text{MPa}\), \(f_y = 420\ \text{MPa}\) and modulus of rupture \(f_r = 0.7\sqrt{f'_c}\). Beam: 300 mm × 500 mm, effective depth 450 mm, reinforced with 3 – 20 mm φ bars.
