During Service stage what is the stress at the bottom of the section of a 12m simply-supported rectangular beam (H= 1000mm B=400mm) loaded with 5kN/m uniform live load, given that the initial prestress is 1800MPa, while the total prestressed loss is 5% of the initial? note that the unit weight of concrete is 23.56kN/m^3. the total area of the cable used is 300sqmm located at 50mm from the bottom of the section. use Mt=Mdl+Mll. answer should be in MPa
