What is the action of twisting or bending an object described as?

The action of twisting or bending an object is accurately described by the term "Verdrehung." This German word translates to "twisting" in English, and it captures the essence of the physical action where an object undergoes torsion, resulting in a change to its original shape. This concept is particularly significant in mechanics and engineering, as understanding the effects of twisting on materials is crucial for applications involving stress and strain analysis.

Other terms in the options list refer to distinct actions or objects. For instance, "Entlüften" typically means venting or releasing pressure, "Beilagscheibe" refers to a washer, and "Riss" signifies a crack. Each of these terms relates to different aspects of materials or processes but does not describe the specific action of twisting or bending. Thus, "Verdrehung" stands out as the most appropriate choice for the question posed.
