Practice session

A singly reinforced rectangular reinforced concrete beam has width b = 250 mm, effective depth d = 550 mm, concrete cube strength f_cu = 30 N/mm², and steel yield strength f_y = 400 N/mm². Under the Egyptian Concrete Code (ECP 203-2020) Ultimate Limit State, if the design bending moment is M_u = 240 kN·m, what is the required longitudinal tensile steel area A_s? (Use material safety factors γ_c = 1.50, γ_s = 1.15; design curve factor J ≈ 0.774).
