A concrete beam is reinforced by three steel rods placed as shown. The modulus of elasticity is \( 3 \times 10^{6} \mathrm{psi} \) for the concrete and \( 29 \times 10^{6} \) psi for the steel. Using an allowable stress of \( 1342 \mathrm{psi} \) for the concrete and 20 ksi for the steel, determine the largest allowable positive bending moment in the beam. The largest allowable positive bending moment in the beam is kip.ft.
