Beams are horizontal linear elements that span openings and resist deflection primarily by bending. Which option best fits this description?

• A. Beams
• B. Columns
• C. Slabs
• D. Bracing

Answer: (A)

Beams are the horizontal, linear members that span between supports and carry loads primarily by bending. This bending resistance causes deflection to be limited along the length of the member. Columns, in contrast, carry loads mainly in compression along a vertical orientation. Slabs are flat, two-dimensional elements that distribute loads in both directions rather than acting as slender horizontal spans. Bracing provides lateral stability to resist horizontal forces rather than controlling vertical bending. Given the description—horizontal linear element that spans openings and resists deflection mainly through bending—the beam best fits.
