Which term refers to forces applied to the scaffold due to movement?

The term that refers to forces applied to the scaffold due to movement is dynamic load. Dynamic loads are those that result from forces that change or fluctuate over time, such as the movement of workers, materials, equipment, or environmental factors like wind or vibrations. This can cause varying pressures and stresses on the scaffold, making it essential to design scaffolding to withstand these kinds of loads.

Understanding this concept is critical in scaffolding design and application, as dynamic loads can significantly impact the stability and safety of a scaffold structure, requiring engineers and builders to account for these forces during the planning phase to prevent accidents and structural failure.
