The compression bar made of the same material, the greater its flexibility, the easier to instability
The critical pressure of the compression bar is directly proportional to the elastic modulus of the material
Two compression bars with the same material, length, cross-sectional area and constraints must have the same critical force
For axial compression members, because the normal stress on the cross section is evenly distributed, it is not necessary to consider the reasonable shape of the cross section
