What are the two components found on a W shape beam?

A W shape beam, commonly known as a wide flange beam, consists of two primary components: the flange and the web. The flanges are the horizontal top and bottom sections of the beam, which help to resist bending forces and provide structural stability. The web is the vertical section that connects the flanges and carries shear forces. Together, these components enable the beam to handle various loads and serve its function effectively in construction.

The other options refer to different elements found in structural systems. Beam and column, while crucial components in construction, are not specific parts of the W shape beam. Bracing and sheathing relate to the structural elements used for stability and protection, but they do not form part of the beam itself. Rivet and plate typically pertain to fasteners and connections used in assembly rather than components of the beam structure. Thus, the correct answer identifies the specific parts that make up a W shape beam, highlighting the critical nature of the flange and web in its design and function.
