Required information Skip to question The beam AB supports a uniformly distributed load of 480 lb/ft and two concentrated loads P and Q. The normal stress due to bending on the bottom edge of the lower flange is +14.88 ksi at D and +10.65 ksi at E. (For W8 × 31, S = 27.5 in3.) Draw the shear and bending-moment diagrams for the beam. Hint: What is the relation between load shear and bending moment mathematically? Hint: What is the equation for normal stress in terms of bending moment and section modulus?
