What is the officially approved way to manufacture a stop sign? Is a perfectly made stop sign really a regular octagon, or is it something slightly different? (My hope is that the answer varies from state to state.) Jim Propp
Here's the DOT's regulation: http://mutcd.fhwa.dot.gov/htm/2003r1/part2/part2b1.htm#section2B04 It just says "an octagon" with a height and width that depends on where it's used. On Fri, Mar 28, 2014 at 7:31 AM, James Propp <jamespropp@gmail.com> wrote:

I thought red octagonal stop signs are an international standard, except for "STOP" being in the local language. But, this being posted to math-fun, I would think the intended interpretation is how to fabricate stop signs while minimizing the usage of sheet metal. -- Gene

For me, the fun would come from seeing how different states come to grips with the irrationality of the square root of 2. (Compare with the recent discussion of the shape of home plate in baseball.) Jim On Friday, March 28, 2014, Eugene Salamin <gene_salamin@yahoo.com> wrote:

Their sheet metal shop has access to a math whiz who looks it up in a handbook. For a 1 meter sign, sqrt(2) = 1.4142 is good enough for government work. -- Gene
