In a roof ventilation scenario, the load type corresponding to weight distributed along the roof ladder is

• A. Live load
• B. Dead load
• C. Distributed load
• D. Impact load

Answer: (C)

The main idea here is how loads are applied to structures. A load that is spread along a length or across an area is a distributed load. When weight is placed along the length of the roof ladder, it isn’t focused at a single point but acts over the entire ladder span. That’s why it’s treated as a distributed load—often described as force per unit length along the ladder.

Compare to other types: a dead load is the permanent weight of fixed parts, which isn’t the scenario described. A live load covers variable loads like a person or equipment, but if that weight were concentrated at one spot, it would resemble a point load rather than a spread-out load. An impact load is a dynamic, shock-like load from sudden forces, which isn’t implied here.
