1 A 250 mm x 125 mm I-beam having I, 3717-8 W V, y 30° U, x cm² and Iy = 193-4 cm4 is used as a purlin on a roof truss. The angle of inclina- tion of the beam rafter of the roof is 30° to the hori- zontal and the rafters are placed 4 m apart. If the vertical load on the purlin is 10 kN uniformly dis- tributed, determine the maximum stress and the maximum vertical deflec- tion of the purlin. Take the purlins to be simply sup- ported at the ends and E = 200 GPa. mpm 30° Fig. 9.16
