Which of the following is NOT an example of dynamic loading?

Dynamic loading refers to forces that change over time, affecting structures or equipment in ways that can lead to different stress levels and failure modes. In this context, a balanced load condition represents a stable and static state where loads are evenly distributed, neither increasing nor decreasing, and thus does not introduce variability in forces. Therefore, it does not exemplify dynamic loading since it lacks the time-dependent factors associated with dynamic scenarios.

In contrast, shock loading represents sudden impacts or forces applied to a structure, while high temperatures can lead to material expansion or contraction affecting structural integrity. Likewise, time under pressure conveys conditions that can lead to fluctuating loads and stresses, typical characteristics of dynamic loading conditions. Each of these emphasizes changes that might occur over time rather than presenting a stable, balanced situation.
