Classification of Mechanisms Using graph representation, mechanism structures can be conveniently represented by graphs. The classification problem can be transformed into an enumeration of nonisomorphic graphs for a prescribed number of degrees of freedom, number of loops, number of vertices, and number of edges. The degrees of freedom of a mechanism are governed by Equation (4.3). The number of loops, number of links, and number of joints in a mechanism are related by Euler’s equation, Equation (4.5). The loop mobility criterion is given by Equation (4.7). Since we are primarily interested in nonfractionated closed-loop mechanisms, the vertex degree in the corresponding...
