What Makes a Ship Move?
One of the problems that often confronts engineers is the description of large, interconnected systems. Engineers tend to specialize, so that one is very knowledgeable on gears, another knows bearings, a third knows pumps, but none of them are comfortable with the whole system. In the automotive context, this is often expressed as, "How does the engine cause the car to move forward?" On the one hand, most engineers can describe the process in words, but they are far less quick to talk about equations for the whole system. Here, I will address a similar modeling question in the marine context, "What makes a ship move?"
