Rod

A rod is a straight, slender object, typically cylindrical, that is used for various purposes across different fields. In physics and engineering, it often refers to a linear structural element that can support loads. In fishing, a rod is a long, flexible tool used to catch fish, equipped with a reel and line. In measurements, a rod is also a unit of length equal to 16.5 feet (approximately 5.03 meters), historically used in surveying. The term can apply in various contexts, but it generally indicates a long, thin piece of material designed for specific functions.
