something you did not know

[hevnsnt]

Did you know that manhole covers are round, that way no matter which way you try it wont fall into the hole.

 

[Electric Amish]

yes

 

[Lazy8s]

It'll fall in if you use a jackhammer on the surrounding concrete.

 

[hevnsnt]

lol true

 

[minendo]

Remember this people as this is often an interview question.

I was asked not too long ago and was given 10 seconds to answer. I answered and the 7 people interviewing me were in shock. It was the first time they had anyone provide the right answer.

Ended up getting the job and start in two weeks. 🙂

 

[godmare]

yeah, that's why they're round.....

Yep, I've heard that before.

 

[Scrooge2]

yes it's a common interview question. but I dont understand why. if it's round why wouldn't it fall in the whole? Is there a ledge under the cover? If so a cover of any shape wouldnt fall in either if it's got a ledge underneath.

No matter what way you turn it and can't fit through. Other objects can be turned in such a way that they will fall through.

It is a common interview question because it can be used to see a candidates thought process as well as problem solving skills.

Think really hard about what you've just said. About there being a ledge under the cover.. and how it would stay up if there wasn't.

That's what they told me. Guy that asked the question said that most people just sit quiet for 10 seconds because they have no idea what to say.

This started as a Microsoft interview question, I believe. They have all sorts of weird stuff to get you thinking outside of the box. For example, "How do they get the peanuts inside M&M's?

If you took the lid off a jar and tried to squeeze it into the opening, did you ever wonder why it won't go in? It's because the circle has a diameter bigger than the hole. Since no matter which way you turn or rotate a circle it'll always be the same diameter wide, it will never fall in.

Need to re-evaluate your logic on that ledge theory :roll:

Yeah, McDonald's doesn't seem to get to many bright candidates. You must've really blew their minds!


It's a fundamental characteristic of circles and spheres to have the same dimension, from all angles.

yep.

BTW - you would not get the job.

 

[CarpeDeo]

Any manhole with an odd number (greater than 1 of course) of equal length sides cannot fall in either.

"How do they get the peanuts inside M&M's?

And how is that difficult? The manufacturing process should be relatively straightforward.

You'd be amazed at how many people would freeze up or make up some crazy processes.

It's not how do they get the peanuts in, it's how do they get the little m's on.

 

[Fritzo]

Yep, my manhole is round, but I don't let anything even ATTEMPT to fall into it :Q

Uhh... if the hole was the exact size of the cover, the cover will definitely fall right through. So there is a ledge. And if the ledge was REALLY big, then almost any shape wouldn't fall through. Regardless, I always give different answers. 1) It's easy to roll around if you wanted to move it. 2) There's no corners so it's not hard to align. 3) Easy to make.
