Dynamic loading is applied forces that change over time, including loads that change where they are applied, the direction they are applied, and the magnitude. They are further categorized as periodic, random, or a combination. Periodic loads occur at regular, measured intervals, while random loads are unpredictable.

Static loads are loads that are applied to a structure or a component and are not expected to change over time. Examples of static loads include the weight of a building or the weight of a car. Dynamic loads, on the other hand, are loads that vary with time and are often caused by the movement or vibration of a structure or component.
