Q:
Why  are  manhole  covers  round ?
 
 
 
 
 
 
 
 
 
 
So far we have heard the following answers:
  • from nick_kt:Round cover is easier to transport.

  • from alex:Round cover can't go through if dropped.

  • from anon1:Round cover takes less metal to manufacture.

  • from :Because round holes are easier to dig.

  • from teegalapalli:Becasuse only circular covers can fit the hole perfectly in all the 360 degrees, where as other shapes will not do the same and leaves some gap on which if some one steps on will disturb its stability.

  • from Alan_App:Thermal expansion will be symmetric for the circlular manhole,explosions? plus it's gotta make life easier for sewage inspectors...I imagine there is quite a lot of weight in those things.
