Which term denotes load delivered in a very short time?

• A. Lateral Impact Load
• B. Impact Load
• C. Concentrated Load
• D. Axial Load

Answer: (B)

Impact load denotes a load delivered in a very short time. It describes a force that is applied suddenly, creating a high peak and dynamic effects because the structure and any attached masses must respond almost instantaneously. This is different from sustained static or quasi-static loads, which are applied gradually. Lateral impact load is simply a directional case of an impact, while axial load refers to force along the structural axis, and concentrated load describes where the load is applied (a single point) rather than how quickly it is applied. In practice, recognizing impact loads helps account for the sudden, high forces from events like falling objects, equipment drops, or vehicle impacts.
