For this assigment we decided to use dynamic structures doe the adaptability and flexibility they bring. It consists of two rigid elements hinged together, that leave us we diferent posibilities for the design; this means that the system can be stabilized by placing a rigid element.  Our resarch was bases in exploring two sistems regular and excentric the idea was to change the place of the hinged from the middle to 1/3 of the length and by it, explore thechanges in the structure. From joining the components together we develop a structure that was based on an arc form.   This system is capable of keeping a constant tension if we add stretch wired as guides during the travel of the structure this will allow a proper path for the structure.
