P8.13 Two uniformly distributed loads of w=3,600 lb/ft act on the simply supported beam shown in Figure P8.13a. The beam spans are a 8 ft and L-16 ft. The beam cross section shown in Figure P8.13b has dimensions of by 16 in., di 6 in., bz 10 in., and dz 10 in. Calculate the maximum tensile and compressive bending stresses produced in segment BC of the beam. FIGURE P8.13a a D FIGURE P8.13b P8.17 A W410 × 60 standard steel shape is used to support the loads shown on the beam in Figure P8.17. Assume P-125 kN, w 30 kN/m, a 3 m, and b-2 m. Determine the magnitude and location of the maximum bending stress in the beam. FIGURE P8.17 D
