The proper name for one of the two principal structural sides of a ladder is a?

• A. Truss block
• B. Beam
• C. Guide
• D. Rung

Answer: (B)

The main concept is that a ladder’s frame has two long, load-bearing members that run along its length. These are the beams that form the sides of the ladder and carry the weight, while the rungs are the crosspieces that provide stepping surfaces between them. A truss block isn’t a standard term for ladder parts, and a guide isn’t the primary structural member. So the term that best fits the two principal structural sides is beam, because it describes the main longitudinal members that bear the load of the ladder.
