Question

In the stabilization of a suspension structure against flutter, which type of cable is typically used with a curvature opposite to that of the primary cables?

Options:

Tertiary cable
Counter cable
Secondary cable
Stabilizing cable

Answer 1

A cable called the counter cable is used in suspension structures to prevent flutter by having a curvature opposite to that of the primary cables, providing additional stability.

Step-by-step explanation:

In the context of stabilizing a suspension structure like a bridge against flutter, a specific type of cable is used that has a curvature opposite to that of the primary cables. The type of cable used in such scenarios is typically known as a counter cable. These cables are designed to counteract the forces experienced by the primary cables and to add overall stability to the structure. The counter cables help in maintaining the structural integrity of the suspension system by preventing unwanted oscillations that could lead to structural failure, known as flutter.
