Solve the problem indicated below. NEATLY draw the cross section of each beam and all diagrams that are recommended to be employed in the solution process. That is: (1) draw the cross-sectional area of the beam with all pertinent dimensions, rebar, and distances; (2) draw the strain diagram with all details (strain names, triangles, and distances); (3) draw the stress diagrams; and (4) draw all resultant, tension, and compressive forces with their corresponding moment arm(s). Problem 2 (Singly reinforced beam with two layers of reinforcement): Consider a rectangular beam with b=11 in and h=16 in under positive bending. The compressive strength of the concrete is 3000 psi and the yielding stress of the steel is 60 ksi. The tension reinforcement consists of two layers of 4 #7 bars each. That is 8 #7 bars in total. The minimum concrete cover is 1.5 in and minimum bar separation is 1 in. Since we do not know the stirrups employed in this beam, use typical approximated distances for d and dt. For example, d = h - 3.5 = 16 - 3.5= 12.5 in. Calculate all necessary quantities and intermediate quantities to obtain ÞMn.
