What kind of conditions can lead to dynamic loading?

Dynamic loading refers to the application of loads that change over time, often causing a varying response in structures or systems. Excessive use typically leads to dynamic loading because it invokes repeated or fluctuating stresses that exceed the normal operational parameters of a system. This can occur in situations where machinery or electrical components are subjected to high usage rates, leading to abrupt increases in load due to sudden or recurrent operations. Such conditions are particularly critical in the context of electrical grids and rigging applications, where the integrity of the system must handle fluctuations in load effectively to prevent failure.

In contrast, steady-state loads are consistent and predictable, often resulting in static loading rather than dynamic effects. Constant weight applications maintain a uniform load, which also does not contribute to dynamic conditions. Low-frequency vibrations can indeed cause some level of dynamic loading, but the term "excessive use" more directly implies a scenario with substantial variations in operational stress, making it the more suitable choice in this context.
