2. The 20 foot beam shown has a cross-section built up from a 1" x 10" plate welded onto the top of a W8x31 section. Given that the load applied to the beam is w = 1.2 klf, determine the following: e. Maximum bending stress f. Bending stress where the 1" x 10" plate joins the W8x31 9. h. Maximum shear stress Shear stress where the 1" x 10" plate joins the W8x31 20' I -I"x10" STEEL PLATE (CENTERED) W Bx 31 A 36 STEEL, F= 22 KS1 Fv= 14.5ksi Ay FBD Section By GIVEN: CENTROID IS LOCATED AT 6.35" lx = 207.5 in M V 6.35"
