Which of the following is NOT typically part of fire dynamics?

The correct answer highlights that structural engineering principles are not typically categorized within the study of fire dynamics. Fire dynamics primarily focuses on understanding the behavior and movement of fire and the various factors that can influence it. This includes concepts such as heat transfer mechanisms, which examine how heat moves through different materials and space, fire growth patterns that describe how fire develops over time, and how it spreads through various environments.

On the other hand, while structural engineering principles are crucial for building design, safety, and understanding how structures behave during a fire, they do not directly address the physical and chemical processes involved in fire behavior. Structural engineering is more related to the resilience and stability of buildings in the presence of fire rather than the dynamics of the fire itself. Thus, it lies outside the primary focus of fire dynamics.
