Reference problem
=====================


Geometry
---------


.. image:: images/10000201000003170000024311AD39A25549A5A5.png
    :width: 6.889in
    :height: 5.0425in


.. _RefImage_10000201000003170000024311AD39A25549A5A5.png:

The beam has the following dimensions:


* length :math:`l=12\mathit{inches}`


* width :math:`w=\mathrm{1,1}\mathit{inches}`


* :math:`t=\mathrm{0,05}\mathit{inches}` thickness

There is a 90° twist between the start of the beam (embedded) and the free end.


Material properties
----------------------

The elastic properties of the material in question (steel) are as follows:


* Young's module: :math:`E=29\times {10}^{6}\mathit{psi}`


* Poisson's ratio: :math:`\nu =0.22`


Boundary conditions and loads
-------------------------------------

Small face (:math:`w\times t`) embedded (:math:`u=v=w=0`)

Loads: Two load cases on the node in the middle of the other small face


.. csv-table::

    "1. Loading according to width", ":math:`{F}_{z}=–\mathrm{0,5}\mathit{lbf}`"
    "1. Loading according to thickness", ":math:`{F}_{x}=+\mathrm{0,5}\mathit{lbf}`"
