A concrete slab is reinforced by \( \frac{5}{8} \)-in.-diameter steel rods placed on \( 5.5 \)-in. centers as shown. The modulus of elasticity is \( 3 \times 10^{6} \) psi for the concrete and \( 29 \times 10^{6} \) psi for the steel. Using an allowable stress of \( 1400 \mathrm{psi} \) for the concrete and \( 19.7 \mathrm{ksi} \) for the steel, determine the largest bending moment in a portion of slab \( 1 \mathrm{ft} \) wide. The largest bending moment is x kip.ft.
