Determine the maximum uniform distributed load w0 that can be supported by the reinforced concrete beam if the allowable tensile stress for the steel is (σ_st)_allow= 28 ksi and the allowable compressive stress for the concrete is (σ_conc)_allow= 3 ksi. Assume the concrete cannot support a tensile stress. Take E_st= 29(103) ksi, E_conc= 3.6(103) ksi.
