Solve the following problem:
Calculate the maximum distributed load intensity "w" that a simply supported beam of length L = 5 m is able to carry. The geometric and material data of the cross section are: concrete, f’c = 27.57 MPa, width b = 300 mm, height h = 500 mm, depth of the tension reinforcement d = 460 mm; steel reinforcement, As = 602 mm2, fy = 413 MP a; FRP, f’fu = 2800 MP a, f’fu = 0.017, Ef = 164000 MP a, bf = 200 mm, tf = 1.0 mm, n = 1.
