Which component is considered a member of a truss system?

1. Joists

2. Purlins

3. Web

4. Beams

The correct answer is: Web

In a truss system, the component referred to as the "web" plays a critical role in maintaining the structural integrity and stability of the truss. The web consists of diagonal members that connect the top and bottom chords of the truss, creating a triangular configuration. This design efficiently distributes loads and helps prevent deformation or buckling under stress. The web members work alongside the chords (the top and bottom horizontal components of the truss) to form a framework that can support significant weight while minimizing materials used. Trusses are often employed in roofs, bridges, and other structures where spanning large areas without support columns is necessary. The web's triangular arrangement contributes to the overall strength and rigidity of the structure, making it vital to the performance of the truss system.
