| Subject | [퀴즈] O링의 크기를 알아맞히는 법 |
|
오늘 오전에 상사가 던져준 문제 하나를 풀고 나서, 문득 생각이 나서 글을 써 봅니다. O링이란 게 있습니다. 여자들이 머리 묶을 때 쓰는 고무줄처럼 생긴 것으로, 재질도 고무니까 비슷하지요. 다른 말로는 패킹이라고도 부르는데, 일반적으로 기계에서 부품과 부품 사이의 틈을 틀어막는 데 쓰입니다. 아침에 출근했더니 상사가 커다란 O링 하나를 던져주면서 “시간나면 이 녀석의 호칭번호를 알아내서 보고해라”고 하더군요. 급한 건 아니라서 저녁을 먹고 나서야 이 녀석을 붙잡게 되었는데, 처음에는 막막하더라고요. 호칭번호를 알아내려면 이 녀석의 굵기와 내경(안쪽 지름)을 재어야 하는데, 굵기는 그렇다 치더라도 이렇게 흐늘흐늘 말랑거리는 녀석의 안쪽 지름을 대체 무슨 수로 재어서, 호칭번호를 알아낼 수 있을까요? 참고로 사무실에 있는 측정 도구는 5 m짜리 줄자 하나와 디지털 캘리퍼스 하나뿐입니다. (제 필통을 뒤져보면 15 cm짜리 자가 하나 있긴 하지만, 쓰지 않았습니다.) 참고로 디지털 캘리퍼스로 측정한 해당 O링의 굵기는 약 5.7 mm였습니다.
여기서 문제 : 저는 어떻게 위에 있는 도구와 표만으로 문제의 O링 호칭번호를 알아내었을까요? 힌트는 간단한 수학입니다.
