Why is it better to have round manhole covers than square ones?

Answer 1

A square manhole cover can be turned and dropped down the diagonal of the manhole. A round manhole cannot be dropped down the manhole. So for safety and practicality, all manhole covers should be round.

Answer 2

Round manhole covers enable turning from left to right, and allow it to be taken out from any angle when at a slant.

Square ones allow only 6 worthy points from which to take off the cover (top, below, and 4-sides).

Either analysis seems alright, although may have nothing to do with why they are like that in the first place. Just me thoughts.

Answer 3

two reasons one has to do with it will not fall back into the manhole and second reason is it only has one stress point where a square one has 5. a square one can bend a lot easier.

Answer 4

Well, gee, what a lot of sticks in the damp soil.
Manhole covers are round because manholes are round. That's about it.
And they are "MANholes" because "WOMANholes" is just too nasty.

Answer 5

round covers better fit the round holes than square ones me thinks

Answer 6

A round cover no matter how it is orientated can not fall through the open hole. A square can be turned to fall in the hole!

Answer 7

A round one cant fall in while a square one can. I mean do you really want to be the ****** that has to climb down there to lug it up when it falls in?! Yuck!

Answer 8

Because the holes are round!!!

Answer 9

Thats a very complicated question for me because i do not understand this:-)
