Extracted text: Figure 4 shows a rectangular hollow steel bar welded to a vertical member. The bar has to support a IkN load at its free end. Fillet welds extend all around the outer periphery of the bar. Assuming that the Distortion Energy Theory is applicable, i.e., Say = 0.58 x S, determine the required weld size using a welding rod with S, = 330 MPa and a safety factor of 3 based on yielding. Neglect the weight of the rectangular bar. 1 kN 60 2 25 15 Figure 4 with all dimensions given in millimetres
