How do static loads differ from dynamic loads?

Static loads differ from dynamic loads primarily in terms of their behavior over time. Static loads remain constant and do not change, while dynamic loads vary with time or motion. An example of static load is the weight of a structure or the load of furniture in a building, which remains steady. On the other hand, dynamic loads involve forces that change, often due to movement or external actions, such as wind forces on a structure, vibrations from machinery, or impacts from vehicles. Understanding this distinction is crucial in engineering design, as structures must be able to support both types of loads effectively to ensure safety and functionality.
