The AB beam has a total length of 8m. AC, CD, CE, EF and EB bars only work in tension and compression. In the middle of the CE bar, a device allows a shortening between two points C and E, which is translated by an elongation of the left and right parts of the CE bar by :math:`\mathrm{\delta }` = 6.52mm. The support in A is fixed while the support in B is mobile.


Liaisons
--------


* Supports A (DX=DY=DZ=0, KRX = = KRY = KRZ =0.0001 N.m/rad)


* Supports B (KY = 1 x 109 N/m)
