Whoops – math errors! 60MPH = .088 feet
per 1/1000 second. That’s 1.056 inches. 80 MPH = .117 feet per 1/1000
sec. or 1.408 inches. 5MPH = .007 feet or 9/100 inch in 1/1000 sec. At any
speed a luge sled doesn’t go very far in 1/1000 of a second!

Hi Aaron. I got the .3 to .4 second eye blink time from a post by
an optometry student here:
http://www.madsci.
From men’s start you’ll be going a lot faster at the
finish than you would from a lower start. For example let’s say that a
sled going from women’s start on a certain track does 60MPH at the finish
while one from men’s start crosses the finish at 80 MPH. The
“slower” slider is covering 5.28 feet in 1/1000 of a second; the
faster slider covers 7.04 feet in the same time. Of course we have no idea
where on the track Wendell gave up 6/1000 to Huber over 4 runs. If it was at
the start the difference between them would have been quite small. A sled going
5MPH travels about 5 ¼ inches in 1/1000 of a second.
Steve Martel joked that my 1/1000 “winning margin” was
explained by the fact that my foot is a full size bigger than his so I had an
unfair advantage in breaking the finish beam sooner.

I blink of an
eye takes .012 seconds. and that's is off How Stuff Works/luge. and if you were
going from a higher start would the distance at the finish be shorter
or farther apart?

As far as I know the closet Olympic luge finish was ’94 in
. Arnold Huber of , Lillehammer Norway beat American Wendell Suckow for 4th place by .006 seconds over 4 runs. The total distance traveled was over 3 1/3 miles. By comparison, a single human eye blink takes .3 to .4 seconds! Gordy, do you of any closer results? Italy
In a Masters race at an Empire State Games around ’90 or ’91 I beat Steve Martel for 9th place (I think, or maybe it was 10th) by .001 over 2 runs. Steve was a good friend of mine and we both agreed that no matter what the clock showed we had tied.

Subject: [adk-luge] Great SeasonLast night's club race was a blast! What a great way to wind down the
2008 season. I'd like to offer up a big thank you to all the club
members and supporters. You guys are the best. Special thanks go to
the club officers, USA Luge coaches and staff and track workers with a
singular thanks to Jim Murphy for all he does for us.
I find it such a rush knowing we individually have exclusive access to
a $27 million dollar facility at the precise moment the words "Finish
is now clear to start four..." come over the PA and echo off the
mountains. For the next forty-something seconds, it is just you and
the mountain. Okay, in my case considerably longer, but hey, it's all
about the slide right? I mean it's not like we are that competitive a
bunch or anything.
So, getting back to last night's discussion on how close the finishes
were in terms of distance, check out the math:
Assume 82km/hr (presumed peak speed). This equates to roughly
22.8m/sec (given a thousand meters in a km and 3600 seconds in an
hour). Next,converting meters to centimeters -and- seconds to
centiseconds results in a wash (100/100) so the sled travels 22.8
centimeters in a centisecond or roughly 9 inches per hundredth of a
second. If my math is right and I *really* hope it is, a six
thousandths of a second (milliseconds) difference amounts to 13.67cm
or 5.38 inches. How amazing is that? Our team sliders rock!
Anyway, thanks all. I've already begun my visualization techniques to
make the chicane appear just a couple centimeters wider in
anticipation of another great season.
