A rectangular beam with a width of (9536/1150)-in,and effective depth of (9536/900)in is Reinforced with a single high strength steel bar that has a cross- sectional area of 0.42 in2.The bar has a normal tensile strength of 145 ksi, linear stress-strain curve to failure, and a strain at failure of 1.8 percent. The concrete strength fc= 6000 psi. Calculate the nominal flexural strength of the section.
