Beam is?

Beam is?

• A. Main structural member of ladder that supports the rungs
• B. The top section of a ladder
• C. The rope used to raise the ladder
• D. The curved end of a ladder

Answer: (A)

The main idea here is that the beam is the backbone of a ladder. It is the primary structural member that runs along the sides and to which the rungs are attached. This beam carries the load when someone steps on a rung, distributing that weight through the ladder and into the ground. Because the rungs are fixed between these beams, their strength and stability depend on the beams’ integrity. In short, the beam provides the essential frame that holds everything together and keeps the ladder rigid and safe to use. The top section, the rope used to raise the ladder, and the curved end are separate components with different roles and do not serve as the main load-bearing backbone.
