Which of the following is the attribute of ideal column according to Euler?(a) material is non homogenous(b) material is isotropic(c) load does not act along centroidal axis(d) column ends are fixedThis question was posed to me in examination.The origin of the question is Elastic Buckling of Slender & Built-up Compression Members topic in portion Design of Compression Members of Design of Steel Structures

Answer»

The CORRECT option is (b) material is isotropic

To ELABORATE: According to Euler, the following are the attributes of ideal column: (i) Material isisotropic, homogenous and is assumed to be perfectly elastic, (ii) column is initially STRAIGHT and load acts along centroidal axis (no eccetricity of loads), (III) column has no imperfections, (IV) column ends are hinged.
