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....

Not really stupid.
1) Mancovers are heavy, easy to roll
2) They stack easily
3) Cannot fall into hole
4) Round is easy to manufacture
5) Humans are far more ‘round’ than rectangular - we fit into holes easily
6) Cannot wedge into place
7) Traffic causes them to rotate in place, thus preventing corrosion from rusting them into place
8) Easy to pry out of hole, via single hole
9) Easy to fit into hole, as they are self-centering
10) Because thermal expansion is radial - they will not cause ‘cracks’ at corners; this makes it safer as the round mounting ring is large enough to allow the round manhole cover to ride ‘up’ a few millimeters, instead of expanding and cracking concreteas would happen in another geometric shape.

Plus, those which you listed. They were looking for technical analysis; I thought this was a good tool for checking critical thinking.
