Figure 2 shows a construction with two rods where these are assembled with an articulated connection in A. The rods are supported by fixed articulated bearings in points B and C, respectively. In point A, a point load F1 acts. The rods are hollow profiles of steel. Appendix 1 shows cross-sectional parameters for hollow profiles. The size of the load, the direction of the load, the lengths of the two rods and the type of hollow profile depend on the last digit of their candidate number and are given in Table 2.
