[고2] 2025 09월 – 39번: 접기(origami)에 적합한 종이의 고유한 기계적 특성

 

Paper's mechanical properties lend themselves to folding and bending. The cellulose fibers of which it is made can be partially snapped in the area of maximum bend, allowing a permanent crease to form, while sufficient fibers remain undamaged for the material not to crack and fall apart. Indeed, in this state it pretty much maintains its ability to resist being pulled apart, but it can also be torn easily and accurately along the crease if a point of weakness ─ a small, initial tear ─ is opened up. This winning combination of mechanical properties allows it to assume the shape of any object through creasing and folding ─ hence the art of origami. There are very few materials as good: metal foils can hold a crease, but control of the crease is somewhat more difficult. Plastic sheeting doesn't tend to hold a crease at all, unless it is very soft, in which case it lacks the rigidity required of a good wrapping material. So it is its ability to hold a crease while remaining stiff that makes paper uniquely suited to this purpose.

근거	종이는 접기와 굽힘에 잘 맞는 기계적 성질을 가지며, 섬유가 부분적으로 끊어져도 갈라지지 않고 접힘을 유지한다	Paper's mechanical properties lend themselves to folding and bending. The cellulose fibers of which it is made can be partially snapped in the area of maximum bend, allowing a permanent crease to form, while sufficient fibers remain undamaged for the material not to crack and fall apart.
설명	종이는 잡아당김에는 강하지만, 약점을 만들면 접힌 선을 따라 쉽게 찢을 수 있다	Indeed, in this state it pretty much maintains its ability to resist being pulled apart, but it can also be torn easily and accurately along the crease if a point of weakness ─ a small, initial tear ─ is opened up.
응용	이런 성질 덕분에 종이는 접기와 주름으로 어떤 형태도 만들 수 있으며, 이는 종이접기의 기반이 된다	This winning combination of mechanical properties allows it to assume the shape of any object through creasing and folding ─ hence the art of origami.
대조	금속 박막은 주름을 잡을 수 있지만 제어가 어렵고, 플라스틱 시트는 주름이 잘 잡히지 않거나 너무 부드러워 뻣뻣함이 부족하다	There are very few materials as good: metal foils can hold a crease, but control of the crease is somewhat more difficult. Plastic sheeting doesn't tend to hold a crease at all, unless it is very soft, in which case it lacks the rigidity required of a good wrapping material.
결론	주름을 유지하면서도 뻣뻣함을 갖춘 성질 덕분에 종이는 포장재와 접기 예술에 독보적인 재료가 된다	So it is its ability to hold a crease while remaining stiff that makes paper uniquely suited to this purpose.
