Title: Distance between the timing lights?
Post by: JimCompCNC on August 21, 2009, 12:59:51 PM

Does anyone know exactly what the distance was between the timing lights ?

Thanks

Which 132' equals 1/40 of a mile, making the math easier on those not using a computer.

Also  2.5% of the measured mile.

Thanks guys.

I just wanted to find the trap time slice in the data logger.

I'm suprised that as precise as you guys are that nobody touched "exact" and measurement. 132' is also 2 surveyor's (Gunter's) chains.

In mathematics
132 is the sixth Catalan number. It is a pronic number, the product of 11 and 12. As it has 12 divisors total, 132 is a refactorable number.

If you take the sum of all 2-digit numbers you can make from 132, you get 132: 12 + 13 + 21 + 23 + 31 + 32 = 132. 132 is the smallest number with this property.[1]

But there is no number that, when added to the sum of its own digits, adds up to 132, making 132 a self number. However, 132 is a Harshad number, divisible by the sum of its base 10 digits, as well as a Zuckerman number, divisible by the product of its base 10 digits.   willie buchta

OK Willie, since you did that, i'll add this to help with units of measure
Oh those Brits...  great sense of humor!

Gunter's Chain:
"Dimensurator or Measuring Instrument whereof the mosts usual has been the Chain, and the common length for English Measures 4 Poles, as answering indifferently to the Englishs Mile and Acre, 10 such Chains in length making a Furlong, and 10 single square Chains an Acre, so that a square Mile contains 640 square Acres." ---John Ogilby, Britannia, 1675

Gunter divided the chain into 100 links, marked off into groups of 10 by brass rings which simplified intermediate measurement. On the face of it, the dimensions make no sense: Each link is a fraction under 8 inches long; 10 links make slightly less than 6 feet, 8 inches and a full length of 66 feet.

The chain as a unit of length of 66 feet and the link, one-hundredth of a chain, probably developed as a result of the introduction of Gunter's chain as the technique of surveying; but it is important not to confuse the two; Gunter's chain is the physical device used in the field. A chain also had the commonly used subunit variously called a "rod," a "pole" or a "perch," which was 16.5 feet long, or one fourth of a chain.

So...

2 chains is 132 feet

Got it now. :evil:

Willie et all, you never cease to amaze me.  As do many on this forum.  Keep it up all, I learn things I never thought I would.

Willie --

I am impressed!

And using capital letters, punctuation and paragraphs, too!

Sure you didn't have a little help here?  Someone posting under your name?
