Consider two axially loaded columns, namely, 1 and 2, made of a linear elastic material with Young’s modulus  MPa, square cross-section with side 10 mm, and length 1 m. For Column 1, one end is fixed and the other end is free. For Column 2, one end is fixed and theother end is pinned. Based on the Euler’s theory, the ratio (up to one decimal place) of thebuckling load of Column 2 to the buckling load of Column 1 is ________
