An AISI 1050 HR solid tube of 20mm diameter is acted by force F1 = IkN, and force F2 of
2kN. The tube is welded to a larger round base by 3mm fillet weldment, the base is connected to
the ground base (shown in gray color) by means of four bolts M8x1.25mm (property class of
4.8)). The bolts are evenly distributed at 20mm away from the center of the tube.
