Jeopardy gets slope degree/percent wrong
 
I recall discussions here long ago about the difference between slope angle measurements in degrees and percent. Tonight on Jeopardy in the combination of a clue and correct response, they said Talladega race course turns are banked at a maximum of 33 percent. According to NASCAR, the steeper curves are banked at 33 degrees, or about 65 percent.

I remember the original topic. If I remember correctly it had more to do with blowhards than anything else. But this is RSA so.........oh well.

But what is 100%? Is a horizontal line 0 and the vertical of a 90 deg. 100%? "per cent" of what? 360? Never gave it much though. I remember a section of "the peak" at Park City that was supposed to be 54 deg.(?). It seemed straight down.

It is 100% when the amount of rise (or fall, in the case of skiing) is the same as the amount moved forward. The angle where that happens is 45 degrees. There are very few ski slopes that approach that steepness because snow generally won't stay on it.

The mathematical formula is 100 * tan(angle) -- the tangent of the angle multiplied by 100 to convert to percent.

Or, for the mathematically-challenged, multiply or divide by 2.

Huh??? 45 degres = 100 % hows that a multiply/divide by 2?

That's all the math some people can handle.

No ****. I'll try to figure out what I was thinking about in a minute
or so. Maybe...

It works some of the time - for 35 degrees, slope is 70 percent.

Just be thankful they weren't trying to measure the angle in radians.

Yup, just like the broken clock that's dead-on accurate twice a day. ;-)

ROUGHLY half or double. Granted, precision counts for a lot. Still...
