Articulated Assemblages of Rigid Members,.). The joints allow the rigid bodies to rotate but not translate relative to their neighbors. These bodies are called .; in fact, they are typically, though not necessarily, straight bars. The joints connect members to one another in the same way that the hinge and ball-and-socket supports studied

Deformation and Strain,nges in shape and/or size of the body. All real materials undergo some deformation under the influence of forces. To quantify the deformation of a solid body relative to some reference configuration, it is important to introduce the notions of stretch and strain.
