What does 'articulate' mean on a wheel loader?

In the context of a wheel loader, the term "articulate" refers to the machine's ability to bend in the middle, allowing the front and rear sections to pivot relative to each other. This design provides enhanced maneuverability, enabling the loader to navigate tight spaces and work on uneven terrain more effectively. An articulated wheel loader can turn more sharply and maintain stability, making it well-suited for various applications, such as loading and unloading materials in confined areas.

The other options present characteristics that do not accurately describe articulation. While some machinery may have features like a complete 360-degree rotation or extended arms, these features do not relate specifically to the articulated design. Moreover, stating that it can only move straight is incorrect, as articulation enhances the loader's ability to move in various directions rather than restricting its movements.
