Question

A concrete slab is reinforced by 5/8–in.-diameter steel rods placed on 5.5-in. centers as shown.The modulus of elasticity is 3 x 10-psi for the concrete and 29 x 10-psi for the steel. Using an allowable stress of 1400 psi for the concrete and 20 ksi for the steel, determine the largest bending moment in a portion of slab 1 ft wide.
