Which load represents dynamic forces acting on the aerial device during operation?

• A. Dead Load
• B. Shuttle Valve
• C. Live Load
• D. Ironing

Answer: (C)

Dynamic forces during operation are the variable, time-changing loads placed on the aerial device as it’s used—such as a worker on the platform, tools, or loads being carried as the boom moves. These changing conditions are described as live loads because they come from usage and motion. Dead load is just the permanent weight of the equipment itself, a fixed quantity. A shuttle valve is a hydraulic component, not a load type, and ironing isn’t a relevant term here. So the live load best represents the dynamic forces acting on the aerial device during operation.
