Two steel plates, each ¼ inch thick, are to be joined by two fillet welds. If the joint is to withstand a load of 50,000 lb and an E7014 electrode (allowable tensile strength – 21,000 psi) is used, determine the length of weld at each edge. If the plate width is 10 inches, how would you distribute the weld? Draw a sketch.

Two steel plates, each 5/16 inch thick, are to be fillet-welded to a third one that is sandwiched between them. The width of each of the first two plates is 4 inches, whereas the width of the third one is 6 inches. The two plates overlap the third one by 6 inches, and an E7014 electrode (allowable tensile strength = 21,000 psi) is to be used. If the joint is to withstand a load of 190,000 pounds, use a sketch...
