The critical buckling load of a cast iron hollow cylindrical column 3 m in length when hinged at both the ends is equal to P kN. When the column is fixed at both the ends, its critical load increases to (P + 300) kN. If the ratio of external to internal diameter is 1.25 and E = 100 GPa, determine the external diameter (in mm) of the column.
