The subject online axial Euler buckling solver can determine the Euler buckling load for an axial member with up to
5 segments each with its own elastic modulus and area moment of inertia.  Boundary conditions of free, simple
support, fixed slope and or elastic spring can be applied at the start and end of each segment.  The output
includes the buckling load, maximum compression stress using the smallest input area and a slenderness ratio
using the full length and smallest EA value.  The later two output parameters can be used to determine if Euler
buckling is an adequate representation of the simulation.  Compression stress values approaching the material
yield and low slenderness ratios suggest nonlinear buckling maybe more appropriate.
