Since we have so many engineers on this net, I thought the following might
be of interest....
Engineering
Railroad tracks The U.S. standard railroad gauge (distance between
the rails) is 4 feet, 8.5 inches.
That is an exceptionally odd number.
Why was that gauge used?
Because that's the way they built them in England, and the U.S.
Railroads were built by English expatriates.
Why did the English build them that way?
Because the first rail lines were built by the same people who built
the pre-railroad tramways, and that's the gauge they used.
Why did "they" use that gauge then?
Because the people who built the tramways used the same jigs and
tools that they used for building wagons, which used that wheel spacing.
So why did the wagons have that particular odd spacing?
Well, if they tried to use any other spacing, the wagon wheels would
break on some of the old, long distance roads in England, because that's
the spacing of the wheel ruts.
So who built those old rutted roads?
The first long distance roads in Europe (and England) were built by
Imperial Rome for their legions. The roads have been used ever since.
And the ruts in the roads? The ruts in the roads, which everyone had
to match for fear of destroying their wagon wheels, were first formed by
Roman war chariots.
Since the chariots were made for (or by) Imperial Rome, they were all
alike in the matter of wheel spacing. The U.S. standard railroad gauge
of 4 feet, 8.5 inches derives from the original specification for an
Imperial Roman war chariot.
Specifications and bureaucracies live forever. So the next time you
are handed a specification and wonder what horse's ass came up with it,
you may be exactly right, because the Imperial Roman war chariots were
made just wide enough to accommodate the back end of two war horses.
Thus we have the answer to the original question.
Now the twist to the story.......
When we see a space shuttle sitting on it's launching pad, there are
two booster rockets attached to the side of the main fuel tank. These
are solid rocket boosters, or SRB's.
The SRB's are made by Thiokol at their factory in Utah. The engineers
who designed the SRB's might have preferred to make them a bit fatter,
but the SRB's had to be shipped by train from the factory to the launch
site.
The railroad line from the factory had to run through a tunnel in the
mountains. The tunnel is slightly wider than the railroad track, and the
railroad track is about as wide as two horses' behinds. So, the major
design feature of what is arguably the world's most advanced
transportation system was determined over two thousand years ago by the
width of a horse's ass!!!
Don't you just love engineering?
