Khan Mubina Journal on Mechanical Engineering 2249 - 0744 2 1 7 15 Kinematic Chains, Distinct Mechanisms, Isomorphism Isomorphism is an imperative topic in the field of mechanism. Isomorphism identification is a difficult problem in kinematic chains. There are number of method given by many researchers. This paper presents the application of the [JJ] matrix proposed by Hasan A [1] for the identification of the distinct mechanisms (DM) from a given kinematic chain (KC). The method is based on the Joint -Joint matrix. The process is fully computational and easy to apply for the purpose. With the help of this method, the study determine easily their distinct mechanism and identify the isomorphism of kinematic chains.
