Consider two types of a column cross-section: a hollow square and a hollow circular section. In both cases the wall thickness is 10 mm and the area occupied by the load-bearing material is 869 mm². Find which of these two column types produces a better buckling performance with relevant calculations supporting your answer. Answer • The outer size of the hollow square section can be calcaulated as mm • The outer diameter of the hollow circular section can be calcualted as mm • The second moment of area for the hollow square section can be calculated as mm4 poction can be calculated as
