i only know from learning about it, but round manhole covers prevent them from falling through the hole by consisting of a curve of constant width. Another exam

i only know from learning about it, but round manhole covers prevent them from falling through the hole by consisting of a curve of constant width. Another example is the Reuleaux Triangle which is a viable shape for manhole covers. https://en.m.wikipedia.org/wiki/Reuleaux_triangle https://en.m.wikipedia.org/wiki/Reuleaux_triangle
- jasikpark 9y agonot exactly a great logic question
- mikeash 9y agoThe problem I have with this question is that it’s based on false pretenses. Plenty of manhole covers are not round.
- JoeAltmaier 9y agoCool! I didn't know this was a thing, but I came up with the same solution independently when asked this question. It also makes a wheel that has a constant tangent from the ground (not a constant axel point) as it turns.
