In summary, Figure 3.1 shows a ship in static equilibrium because the two necessary and sufficient conditions for static equilibrium have been met; the vector sum of the forces are zero and the vector sum of the moments are zero.
Phase diagram is a graphical representation of all the equilibrium phases as a function of temperature, pressure, and composition. For one component systems, the equilibrium state of the system is defined by two independent parameters (P and T), (T and V), or (P and V). Pressure-temperature phase diagram for H2O:
phase diagrams is a type of graph used to show the equilibrium conditions between the thermodynamically-distinct phases; or to show what phases are present in the material system at various T, p, and compositions. “equilibrium” is important: phase diagrams are determined by using slow cooling conditions ⇒ no information about kinetics.
2018. The course is intended to develop the student’s knowledge of ship structures. The focus is on various types of intact structural behavior, building upon concepts from mechanics of materials and statics.

These forces pass through the 2 centroids of the center of gravity (G) and center of buoyancy (B) respectively. Provided ΔS and FB are equal in magnitude and the centroids G and B are vertically in line, the vessel is said to be in a state of static equilibrium. Figure 6.1 shows this situation.
diagrams provide information about systems at equilibrium, they can also assist in predicting phase relations, compositional changes and structures in systems not at equilibrium.
