"Directed infinity" is not a standard term in mathematics or physics, but it could refer to various concepts depending on the context. Here are a couple of interpretations: 1. **Extended Real Number Line**: In calculus and real analysis, the concept of directed infinity might refer to the idea of limits approaching positive or negative infinity. In this context, we often talk about limits where a function approaches positive infinity as its input approaches a certain value, or negative infinity for some other input direction.

A **force chain** is a concept primarily used in the fields of materials science, physics, and engineering to describe the way forces are transmitted through a granular material or a system of interconnected particles. In a force chain, the particles or grains that come into contact with each other transmit force from one to another, creating a network or "chain" of forces throughout the material. This concept is particularly relevant in the study of granular materials like sand, gravel, and other particulate substances.
