... With a cutting plane "A" which has an outward unit normal n on freebody 2, make two freebody diagrams. At the cut section we must place internal reactions (forces) as shown. In general, these forces will be forces distributed over the entire area of the cut section. For freebody 2, consider the forc ...

After the remark quoted above, he added “It illustrates the difficulty of describing particular orbits in an ergodic system.” At the time I didn’t see what he meant and the conversation meandered off to other subjects.

Dynamical system
In mathematics, a dynamical system is a set of relationships among two or more measurable quantities, in which a fixed rule describes how the quantities evolve over time in response to their own values. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each springtime in a lake.At any given time a dynamical system has a state given by a set of real numbers (a vector) that can be represented by a point in an appropriate state space (a geometrical manifold). The evolution rule of the dynamical system is a function that describes what future states follow from the current state. Often the function is deterministic; in other words, for a given time interval only one future state follows from the current state; however, some systems are stochastic, in that random events also affect the evolution of the state variables.
