02: Two plates, 20 mm thick, are welded together by means of transverse-fillet welds. The ultimate tensile strength of a weld metal is 415 MPa. The surface finish factor of the weld surface is 0.5, and the size factor is 0.85. The reliability is 90%. Determine the length of the weld if the factor of safety is 2.5. The transverse force on the welds is 80 kN, which is completely reversed under fatigue loading. Take: A=13mm. 25 A, Toe Good luck
Using SMAW process, E70 electrodes and an A572 steel. Determine the length of the side fillet welds for the full capacity the 125x100x10mm angle tension member as shown below. Assume that the member is subjected to repeated stress variations making any connection eccentricity undesirable. Check the block shear strength of the member. Assume that the WT chord has sufficient strength to develop the weld strengths and the thickness of its web is 12mm. Use U = 0.87 for class use and LRFD Method only
