Name at least 5 reasons why manhole covers are round. (Advanced Micro Devices - AMD).
Didn’t see that question but I’ll take a whack at it:
so the manhole cover doesn’t fall into its smaller hole.
makes it easier to push the manhole cover aside by rolling.
a round manhole cover, having no lateral edges, has less opportunity or ability to flip when undue weight is placed on the edge as opposed to “an edge”.
round is not necessarily as racist as square.
Captain America can immediately field a round manhole cover as a weapon if he lose his shield?
No matter how you place a round manhole cover over a hole, it will always reseat easily. not so with a square manhole cover which needs to seat exactly an turned so it fits in the square hole it cover, requiring more work than a round manhole cover and wasting man hours to complete a job.
This question is now stoopid....
’ Name at least 5 reasons why manhole covers are round.’
1. Can’t fall thru its circular opening.
2. Rotational position doesn’t matter when installing.
3. Can be rolled to transport.
4. Ease of manufacturing, perfect circle after being on a lathe.
5. Greater dispertion of force loading on the edges.
6. Round manholes are the strongest and most material-efficient shape against the compression of the earth around them.
7. A round cover is cheapest to make because it requires the least amount
of metal to produce the largest area (opening).
I’ll stop explaining why but there are more reasons.
1. So they can’t fall in the hole if you tilt them the wrong way.
2. So you can roll them along the ground and move them more easily.
3. So the thermal expansion and contraction is more uniform and causes less stress on the cover.
4. A circular manhole cover requires less metal than a square manhole cover of the same diameter, so it’s cheaper.
5. No sharp corners to cause wear and tear or punctures to vehicle tires.
