Which type of load is applied slowly and remains constant?

The correct response identifies a static load, which is characterized by being applied slowly and remaining constant over time. Static loads are usually associated with weights that are evenly distributed and do not change, such as the load from the structure of a building, furniture, or equipment that does not move. In fire safety engineering and inspection, understanding static loads is essential, as these loads contribute to the overall stability and integrity of structures that must withstand various forces including the potential stressors introduced by fire.

Dynamic loads, in contrast, are those that vary with time, such as loads from vehicles in motion or people moving within a building. Cyclic loads arise and fall in a repeated manner and are typically a result of repetitive movements or oscillations. Impact loads refer to sudden, forceful applications of weight or force, such as a heavy object dropping or colliding with another object. Recognizing the differences between these various types of loads is crucial for ensuring the safety and compliance of structures in fire inspections.
