The answer is in the definition: **polygon of forces**
(*plural* **polygons of forces**) # (mechanics) A polygonal
figure the sides of which are vectors representing several forces
acting simultaneously upon one point, so that the vector necessary
to make the figure closed is the resultant of those forces.

such that at every moment in time the state of the system is close
to an equilibrium state. During a quasistatic process, the system
reaches equilibrium much faster, almost instantaneously, than its

### What are diffused disorganized energy?

Generally considered equilibrium, chaotic, random or entropy,
the sum of forces (mechanical energy) or potentials
(electromagnetic energy) is probably close to zero at whatever

felt (or a potential difference is measured), that would be
considered a type of organization of energy, loss of randomness,
loss of equilibrium. Perhaps a rephrasing of the question or
particular application would help clarify?

### Can you use the change in temperature to predict how long it will take for thermal equilibrium to be reached?

Using partial differential equations, you can estimate how long
it will take to get within some difference between equilibrium and

infinite time to reach complete equilibrium, but for us humans we
can settle for some difference that is so close as to make no
difference to us.
