Infinitesimal and Finite Mechanisms, requirement. However, there are cases where just the opposite is required. In order to answer the question of rigidity we have to know the static-kinematic properties of the structure. In the forthcoming, these properties will be investigated for bar-and-joint assemblies, that is, for structures co

Kinematic Bifurcation,egree of freedom (in our terms: the infinitesimal degree of freedom of a finite mechanism is greater than its finite degree of freedom). The sign of this is that the Jacobian matrix of the constraint functions has a rank deficiency. For a four-bar linkage with equal opposite bars, Litvin (1980) call
