Which term refers to a support structure that helps to maintain the alignment of machinery components?

The term "yoke" refers to a support structure designed to maintain the alignment of machinery components, particularly in contexts where forces and torque are applied. In mechanical systems, a yoke provides stability and guides the motion of the components, ensuring they operate smoothly and efficiently. This helps prevent issues such as misalignment that can lead to increased wear on machinery, operational inefficiencies, or even catastrophic failures.

In contrast, the other terms describe different functional components. An eye typically refers to a hole or loop for fastening, often used in rigging or connections. A grabhook is a type of hook designed to grab and hold objects, frequently utilized in lifting and hoisting operations. A pin is a fastener used to secure components together, but it does not inherently provide the structural support for alignment that a yoke does. Understanding these definitions helps clarify the specific function of a yoke in mechanical applications.
