There is no doubt that the importance of decreasing maintenance and having the same ability to achieve the same target with low weight and no friction in nowadays artificial applications, is daily increasing. Using flexural(also flexure) hinges in a system, at least, leads to all of that advantages. We are going to take a planar mechanical system consisted of four bar mechanism and six bar mechanism, with revolute, after that we replace each revolute joint with super elastic hinge. Doing so we have a gate to build a system, strongly recommended, to achieve the same goal using minimum energy. The main purpose of this research is to elaborate a mathematical apparatus able to estimate the deviation of the considered system before and after replacing revolute hinges taking into account the real performance of the novel system through large bending displacements in the flexure(flexural) hinges.
