Beams on a ladder are best described as:

• A. The cross braces that hold rope
• B. Structural components that run the full length of the ladder
• C. The side rails that light
• D. The steps used to stand on

Answer: (B)

Beams on a ladder are the long structural members that run the full length of the ladder, essentially the rails that support the entire frame. They form the backbone of the ladder, carrying the weight from the user down to the ground and providing a sturdy framework to attach the rungs. Cross braces, if present, help keep the rails aligned and add stiffness but don’t span the entire length themselves. The rungs are the steps you stand on, not the beams. So the best description is the long, load‑bearing components that run the full length of the ladder.
