Governing Equations of Motion
In the previous chapter, we considered certain geometric concepts associated with the motion of a continuous medium. We now wish to consider the set of mechanical laws that are customarily assumed to govern the actual continuum motion. These laws express the well-known mechanical principles of conservation of mass, balance of linear momentum, and balance of angular momentum.
