Which mechanism is most likely used to connect cables to control surfaces?

Clevises are mechanical fasteners that allow for a secure yet flexible connection between cables and control surfaces in an aircraft. They consist of a U-shaped clamp that can be adjusted and secured through a bolt, enabling a strong connection that allows for movement and adjustment, which is essential in flight control systems.

The use of clevises is particularly important in applications where control surfaces need to be precisely manipulated, as they provide the necessary linkage for the control cables that connect the pilot's inputs to the aircraft's control surfaces, such as ailerons, elevators, and rudders. This flexibility is crucial during operations, as it allows the necessary articulation without compromising the integrity of the connection.

In contrast, while hinges are used for rotating connections (like control surfaces pivoting on an axis), pulleys are primarily for guiding cables around corners to achieve longer runs or to change the direction of cable movement. Bearings support rotating components but do not connect cables directly to control surfaces. Therefore, clevises represent the most suitable choice for the specific question about connecting cables to control surfaces.
