A two$-$span $6-$inch one$-$way slab is supported on $12-$in$.-$wide beam with center$-$to$-$center spacing of $16ft.$ The slab carries a superimposed dead load of $10psf$ and a live load of $60psf.$ Using $f_{c^{\text{'}}}=4000$psi and $fy=60$ksi, design flexural reinforcement for the slab. Draw a longitudinal section showing the top and bottom reinforcement. The beam is continuous, but the supports are simple, so there is only negative moment over the center support. Check for shear and deflection.
