A principal characteristic of a hanger is that the support member is in tension. In structural engineering, hangers are designed to support loads in a way that allows the weight of the component being supported to pull downward, thereby creating tension in the supporting member. This is crucial for ensuring that the load is adequately managed without risk of failure. The tensioned support system allows for effective load transfer and stabilization of the structure.

In the context of hangers, the design specifically relies on the ability to handle tensile forces effectively, making it vital for the overall structural integrity. Hangers are often used to support components such as pipes, ducts, or cables, providing stability and maintaining the alignment of these elements within a construction.

While other options might involve different types of support systems or load scenarios, they do not accurately describe the primary characteristic associated with hangers in the way that tension does. Understanding this concept is essential for anyone involved in structural design or visual testing, as it lays the foundation for analyzing loading conditions in various applications.
