Two uniformly distributed loads of w=3300 lb/ft act on the simply supported beam shown in Figure A. The beam spans are a = 7.2 ft and L = 15.9 ft. The beam cross section shown in Figure B has dimensions of b₁ = 18.00 in., d₁ = 5.25 in., b₂ = 10.75 in., and d₂ = 11.25 in. Calculate the maximum tensile and compressive bending stresses produced in segment BC of the beam. W a FIGURE A FIGURE B d₁ d₂ B W D L a b₁ b₂ Otensile= psi compressive psi x
