How Pretensioned Cables Support Suspension Structures

What is one of the pretensioned cables directly supporting the load in a suspension structure?

a) Primary cable

b) Secondary cable

c) Tertiary cable

d) Ancillary cable

Answer:

The primary cables in a suspension structure are the ones directly supporting the load.

When it comes to suspension structures, such as suspension bridges and cable-stayed bridges, one key element that plays a crucial role in supporting the load is the pretensioned cables. In these structures, the primary cables are the ones directly responsible for supporting the load.

Primary cables are typically pretensioned, which means they are intentionally stretched before the load is applied. This pretensioning process helps to counteract the weight of the load and maintain the stability of the entire structure. By applying tension to the cables, they are able to provide the necessary support and distribute the load effectively.

Without the primary cables being pretensioned and directly supporting the load, suspension structures would not be able to function as efficiently and safely as they do. The careful design and engineering of these cables are essential to the overall performance and durability of the structure.
