On any such of diagram, each point represents a state of the material. Once the point has been located, all other thermodynamic properties can be read off. For a single phase, the required point can fall anywhere on the region of the plane representing this phase. Thus, two coordinates are needed to specify a point within that part of the plane.

shear and bending moment diagrams. The basic procedure for determining the shear and moment diagrams is to determine the values of V and M at various locations along the beam and plotting the results. In doing so, we will determine critical sections within the beam. A critical section is one where a critical or maximum stress occurs.
