Modeling A
==============

Characteristics of modeling
------------------------

The model is composed of 10 Euler straight beam elements.


Characteristics of the mesh
----------------------------

It consists of 10 POU_D_E elements.


Tested sizes and results
------------------------------

System eigenvalue (:math:`K+\lambda {K}_{G}`) :math:`X\mathrm{=}0`:

.. csv-table::

    "", "**Reference**", "**Error**"
    ":math:`\lambda` ", "170.701", "0.01"



note
--------

Since :math:`{p}_{c}=\lambda \rho Sg`, (:math:`\rho Sg` represents linear pre-stress), we have as a critical load: :math:`{p}_{c}=\mathrm{1300,84}{\mathrm{N.m}}^{-1}`.
