Which term relates specifically to a mechanical measurement of twist?

The term that specifically relates to a mechanical measurement of twist is "Drehmoment," which translates to "torque" in English. Torque is a crucial concept in mechanics, representing the tendency of a force to rotate an object about an axis. It quantifies the twist that can occur in a mechanical system when a force is applied at a distance from a pivot point or axis of rotation.

Understanding torque is essential for applications such as wrenching bolts, where the correct amount of torque ensures that connections are secure without over-tightening, which could damage the components being fastened. The concept is foundational in various fields, including engineering and physics, where the behavior of rotating systems is studied.

The other terms do not refer specifically to the measurement of twist: "Anziehen" relates to tightening or fastening something, "Entlüften" refers to venting, especially in the context of releasing air from a system, and "Schwergängig" describes something that is difficult to move or operate, often referring to resistance rather than a measure of twisting force.
