2) The weldment shown in the figure is subjected to an alternating force F. The hot-rolled steel bar has a thickness h and is of AISI 1010 steel. The vertical

support is likewise AISI 1010 HR.steel. The electrode is given in the table below. Estimate the fatigue load F the bar will carry if three fillet welds are used. (10pts) Repeat this scenario 3 time with different grade electrode (E7XXX, E8XXX...etc) and different grade AISImaterial while all are held the same. By changing electrode, material property, load, application, how does that effect the design? (10pts).
