3. Calculate φMn. fy = 60000 psi and f’ c = 3500 psi in a 30" x 14" rectangular beam with 4 #11 (6.25 in^2) bars in the bottom, 3" clearance between the bottom and the first row of rebar at the bottom, and 2.5" between the top wall of the beam and top row of rebar 2 #9 (2 inch^2) at the top. The space between the bars at the top and top bottom ones is 21.5 inches.
