An 8 1/2 in. thick one-way slab interior spans 10 ft. It was designed with the reinforcement of #6 size bars at 6.5 in. on center, to be placed with a cover of 0.75 in. However, the same steel was misplaced at a clear distance of 2 in. from the bottom. How much is the reduction in the capacity of the slab reduced to carry the superimposed service live load in addition to its own weight? fc = 4,000 psi, fy = 60,000 psi
