Behind the gauge …. A horse’s behind



Today morning I received the following message on Whatsapp (God bless the creator). While its amusing to think of the fact that we haven’t progressed much beyond a horse’s ass, it’s also fascinating to think of how some of the modern implements, measurements and even social practices are because of a decision taken hundreds or thousands of years back. It makes me wonder if any of our innovations are truly new !! Old wine in a new bottle has a whole new meaning and usage :). If the person who authored this piece is known to any of the readers, please share the name so the credits can be given accordingly. 

Do read, learn and laugh… Happy weekend.

Engineering that endured.
The U.S. Standard railroad gauge (distance between the rails) is 4 feet 8.5 inches. That’s an exceedingly odd number. Why was that gauge used? Because that’s the way they built them in England and English expatriates designed the U.S. Railroads.

Why did the English build them like that?

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 tramways used the same jig and tools that they had used for building wagons, which used that wheel spacing.

Why did the wagons have that particular odd wheel 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?

Imperial Rome built the first long distance roads in Europe for their legions, including 400 years in England. Those roads have been used ever since ….. and the ruts in the roads?

Roman war chariots formed the initial ruts, which everyone else had to match for fear of destroying their wagon wheels.

Since the chariots were made for Imperial Rome, they were all alike in the matter of wheel spacing. Therefore, the United States standard railroad gauge of 4 feet 8.5 inches, is derived from the original specifications for an Imperial Roman war chariot.

In other words, bureaucracies live forever. So the next time you are handed a specification, procedure, or process, and wonder, “What horse’s ass came up with this?”, you may be exactly right because Imperial Roman army chariots were made just wide enough to accommodate the rear ends of two war horses.

Now, a twist to the story:

When you see a Space Shuttle sitting on its launch pad, you will notice that there are two big booster rockets attached to the sides of the main fuel tank. These are Solid Rocket Boosters, or SRBs. The SRBs are made by Thiokol at their factory in Utah.

The engineers who designed the SRBs would have preferred to make them a bit larger, but the SRBs had to be shipped by train from the factory to the launch site. The railroad line from the factory happens to run through a tunnel in the mountains, and the SRBs had to fit through that tunnel. The tunnel is slightly wider than the railroad track, and the railroad track, as you now know, is about as wide as two horses’ behinds.

So, a major Space Shuttle 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.

And you thought being a horse’s ass wasn’t important!

Now you know: 

Horses’ Ass controls almost everything.

Explains a whole lot of stuff, doesn’t it?😀😀
