Question

6. The nominal critical shear stress in a weld metal is calculated to fluctuate be tween -3 ksi and i (i.e. fully reversed stress). A stress concentration factor is consistent with the "End of parallel fillet weld". The weld electrode is E100. The weld surface is similar to a Hot Rolled surface. What is the factor of safety guarding against eventual fatigue failure for the weld metal? b) 1.92 a) 1.55 d) 2.94 c) 2.46 e) None of these
