What is NOT a component of a truss?

In the context of truss structures, a concrete base is not a component of the truss itself. A truss typically consists of various members that are connected to create a rigid framework. These members include the top chord, which forms the upper horizontal part of the truss, and webbing, which refers to the diagonal and vertical members that provide structural support and distribute loads throughout the truss. Gussets are also a critical element, as they are used to connect and reinforce the joints between truss members.

On the other hand, a concrete base serves as a foundational element for structures that use trusses, but it is not part of the truss assembly or structure itself. The truss relies on its specific components to function effectively, while the concrete base provides stability and support for the entire system. Hence, identifying the concrete base as not being a component of the truss is accurate.
