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

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

Analytical solution: the displacement for an element is given by: :math:`\mathit{Ux}\mathrm{=}F\mathrm{/}\mathit{Kx}`

So for :math:`n` springs: :math:`\mathit{Ux}\mathrm{=}nF\mathrm{/}\mathit{Kx}`


Benchmark results
----------------------

Values of the displacement for :math:`x\mathrm{=}L\mathrm{/}2` and :math:`X\mathrm{=}L`, as well as of the effort in the elements (constant):

:math:`U(L\mathrm{/}2)\mathrm{=}0.05m`, :math:`U(L)\mathrm{=}0.1m`, :math:`N\mathrm{=}\mathrm{10N}`


Uncertainty about the solution
