Всем привет:)
Для тех, кто знает инглиш
Interviewer: Now comes the part of the interview where we ask a question to test
your creative thinking ability. Don't think too hard about it, just apply
everyday common sense, and describe your reasoning process.
Here's the question: Why are manhole covers round?
Feynman: They're not. Some manhole covers are square. It's true that there are
SOME round ones, but I've seen square ones, and rectangular ones.
Interviewer: But just considering the round ones, why are they round?
Feynman: If we are just considering the round ones, then they are round by
definition. That statement is a tautology.
Interviewer: I mean, why are there round ones at all? Is there some particular
value to having round ones?
Feynman: Yes. Round covers are used when the hole they are covering up is also
round. It's simplest to cover a round hole with a round cover.
Interviewer: Can you think of a property of round covers that gives them an
advantage over square ones?
Feynman: We have to look at what is under the cover to answer that question. The
hole below the cover is round because a cylinder is the strongest shape against
the compression of the earth around it. Also, the term "manhole" implies a
passage big enough for a man, and a human being climbing down a ladder is
roughly circular in cross-section. So a cylindrical pipe is the natural shape
for manholes. The covers are simply the shape needed to cover up a cylinder.
Interviewer: Do you believe there is a safety issue? I mean, couldn't square
covers fall into the hole and hurt someone?
Feynman: Not likely. Square covers are sometimes used on prefabricated vaults
where the access passage is also square. The cover is larger than the passage,
and sits on a ledge that supports it along the entire perimeter. The covers are
usually made of solid metal and are very heavy. Let's assume a two-foot square
opening and a ledge width of 1-1/2 inches. In order to get it to fall in, you
would have to lift one side of the cover, then rotate it 30 degrees so that the
cover would clear the ledge, and then tilt the cover up nearly 45 degrees from
horizontal before the center of gravity would shift enough for it to fall in.
Yes, it's possible, but very unlikely. The people authorized to open manhole
covers could easily be trained to do it safely. Applying common engineering
sense, the shape of a manhole cover is entirely determined by the shape of the
opening it is intended to cover.
Interviewer (troubled): Excuse me a moment; I have to discuss something with my
management team. (Leaves room.)
(Interviewer returns after 10 minutes)
Interviewer: We are going to recommend you for immediate hiring into the
marketing department. |

Интервьюер: Теперь прибывает часть интервью, где мы задаем вопрос, чтобы
проверить вашу творческую интеллектуальную способность. Не думайте слишком
трудно об этом, только применяйте каждодневный здравый смысл, и описывайте ваше
рассуждение процесса. Вот - вопрос: Почему покрытия люка круглы? Feynman: Они
не. Некоторые покрытия люка квадратны. Верно, что есть НЕКОТОРЫЕ круглые, но я
видел квадратные, и прямоугольные. Интервьюер: Но только рассматривая круглые,
почему они круглы?
