Best Answer

a man hole lid is shaped like a slice of a cone so that the radius of the top side is slightly larger than the radius of the bottom. it kind looks like this \_________/ . that way if you flip it on its side while lifting it it wont fall through. any other shape has a diagonal length longer than the side length and if it flipped on its side when you were lifting it it might fall through make the live of a plumber/civil engineer very upsetting.

Why are potholes round in diameter?

Why are potholes round? That's because it's the natural shape to be formed by the action of wheels, etc. If they started to be square, say, there would be a tendency for the straight parts of the edge to contact the wheel more than the corners. So they would get broken off more. In fact, it wouldn't have got like that in the first place.

What kind of weathering creates potholes?

Freeze-thaw weathering is a common process that creates potholes. Water seeps into cracks in the road, freezes during cold weather, expands, and weakens the pavement material. This cycle of freezing and thawing causes the road surface to break up, leading to the formation of potholes.


Would you find potholes caused by weathering in trooical regions?

Yes, potholes can be caused by weathering in tropical regions. Weathering processes such as rainfall, high temperatures, and humidity can contribute to the deterioration of roads and create potholes over time. The combination of heavy rainfall and intense sunlight can accelerate the weathering process and lead to the formation of potholes in tropical regions.


What are potholes made of?

Potholes are typically made of a combination of asphalt, gravel, and other materials used in road construction. These materials weaken over time due to factors like water infiltration, freeze-thaw cycles, and heavy traffic, causing the road surface to deteriorate and form potholes. Regular maintenance and repairs help prevent potholes from forming.
