Benchmark solution
=====================

Calculation method used for the reference solution
--------------------------------------------------------

The solution is obtained by elementary statics.

.. csv-table::

    "In cable :math:`1-3` "," :math:`\begin{array}{cc}N& =1000\sqrt{2}N\\ & \simeq 1414.2N\end{array}`"
    "In the :math:`3-4` "bar," :math:`\begin{array}{cc}N& =-1000N\end{array}`"


:math:`N=0` everywhere else (and especially in cable 2-4).


Uncertainty about the solution
---------------------------

The reference solution is accurate.
