What is the term for an "articulated" structure in technical language?

The term "articulated" in a technical context refers to a structure that is designed to allow movement at the joints or connections between different parts. An articulated structure can bend or pivot at specific points, which is essential in applications such as robotics, mechanical linkages, and various engineering designs where flexibility and motion are necessary.

The correct choice, which translates to "articulated" in English, emphasizes this characteristic of allowing movement at joints. This term is commonly used in discussions about mechanical systems, vehicles, and architectures that require dynamic capabilities. It is particularly important in scenarios where structures need to adapt to motion or load changes without being rigidly fixed.

In contrast, the other terms do not convey the same idea of flexible movement at connections. For instance, terms such as "stiff," "firm," and "stable" describe properties related to rigidity and strength but do not imply the presence of joints or the ability to articulate. Thus, the selected answer accurately reflects the definition of "articulated" as it relates to structures designed for movement.
