1. Answer the following questions for each cross-section below using the Equivalent Rectangular Stress Block (Whitney Stress Block) for compressive stresses in the concrete. [72 total points] A. What is the nominal moment capacity of the beam (M.)? (6 points) B. What is the distance from the top of the beam to the neutral axis (e)? (2 points] C. Assuming the concrete reaches a strain of 0.003, what is the strain in the extreme tension layer of reinforcing steel? Draw the strain and stress diagrams, specifically labeling c, a, d, d, , , the compressive stress in the concrete, the tensile stress in the steel, the resultant compressive force, and the resultant tensile force. [8 points) D. Would failure of the beam be considered tension-controlled, compression-controlled, or in the transition region? What is the resistance factor (y? [2 points] 2.
