A concrete beam is reinforced by three steel rods placed as shown. The modulus of elasticity is 3 × 106 psi for the concrete and 29 × 106 psi for the steel. Using an allowable stress of 1342 psi for the concrete and 20 ksi for the steel, determine the largest allowable positive bending moment in the beam. 16 in. -in. diameter 8 in. 2 in. The largest allowable positive bending moment in the beam is kip-ft.
