Which load is applied to specific large objects?

The correct choice is concentrated load, as this term specifically refers to a load applied to a particular, well-defined area of a structure, often due to large objects or heavy equipment. In building construction, a concentrated load is characterized by its focus on a single point or a small area, which can impose significant stress on the structural elements beneath it. This can include heavy machinery, machinery supports, or large pieces of furniture, for example. Understanding concentrated loads is vital for engineers and firefighters alike, as it helps assess the potential impacts on a building's integrity and safety during emergency responses.

In contrast, repeated loads are those that are applied to a structure multiple times over time, which is more about fatigue than immediate concentration. Static loads refer to loads that are applied slowly, over time, and remain constant, whereas live loads are those that can change over time with movement (like people or vehicles). These types of loads do not focus on a singular, concentrated point like large objects do.
