A rigid body, as already defined, is an assembly of particles whose relative positions remain unchanged. Actual bodies all deform to some degree when subjected to forces, but the rigid bodies we shall consider are such that changes of shape can be disregarded. The shape of a rigid body, ...

4 Statics Statics is the study of rigid bodies that are in equilibrium and concerned with the analysis of loads such as a force or moment/torque acting on a physical body or system, that is, it is in a state where the relative positions of sub-structures do not vary over time or ...

Elastic networks consist of rigid bodies interconnected with generalized springs. Allowing more general interactions leads to a theory of rigid body systems. Stiffness of an elastic system is defined and computed. Compactification of the space of such systems is conveniently interpreted in a grassmann...
