Fatigue in Paper Clips from Repeated Opening and Closing

The paper clip stands as a commonplace object employed daily to gather loose sheets of paper into neat stacks.

In each instance of use, the cycle unfolds predictably: the outer wire loop is drawn apart from the inner loop to widen the gap, allowing the clip to encircle the paper edges before being let go to constrict and hold.

Through countless repetitions of this opening and closing, faint modifications appear in the clip's structure. The wire's bend eases into a gentler arc, the loops maintain a trace of extra space at rest, and the snap-back motion softens.

These traits coexist with ongoing performance. The clip persists in securing papers for everyday handling, keeping the bundle intact without slipping off during transport.

Such characteristics mark fatigue stemming from repeated cycles of manipulation.
