The work presents shape optimization of the telescopic beam segments cross-section. The starting point for optimization were stress analysis of beams, carried out by various shapes of cross-sections. Based on the findings, a parametrized optimization cross-section was prepared. The shape of this cross-section was optimized using method of statistical design of experiments. Based on the results of the experiment, we prepared mathematical models that connect the cross-section parameters with its area and the stresses on the telescopic beam. These models were used to define the optimal shape of the optimization cross-section.
