I can't remember the word for when the angle of a radar reading reduces the speed reading. It's a little kinematics gig. Everyone knew that if a radar is perpendicular to your car, it can't read your speed, right? The word isn't hysteresis...

No, I didn't get a ticket, I had a bicycle spoke failure from the spoke nipple being square shouldered, which made it protrude straight from from the rim instead of angled towards the hub flange. This made a nice little bending load, and subsequent fatigue failure right at the nipple head. I am trying to take pictures of it, but my camera macro isn't good enought to get the lens in-line with the spokes. So I have to shoot from an angle, which is reducing the demonstration of the angle.

Thanks for your brilliance.

cosine error

Duh (I feel so inadequate). Thanks, Andy. I am flattered that you responded to one of my posts :)

:clonk:

cosine error


Give Andy a cigar! :beers: Cosine Error is CORRECT!
Trigonometry for Dummies..... :D :rolleyes:

Just an FYI, if you have a bad dvd player laying around, you can break it open, grab the lens off it and tape it to your camera lens making a nice macro lens.

What's a DVD Player? Is that anything like Beta Max or VHS?

Hey, I knew it had to do with the angle cosine, I just couldn't pull up the generally accepted term :clonk:

OK, here's one for all the smarty pants among us, what's it called when you look at a gauge at an angle, and the needle appears to be pointing at a number, but it's not number right under the needle when looking at it head on?

Bias, but then I'm biased.:D

OK, how about this one: How much wood would a woodchuck chuck if a woodchuck could chuck wood?

Isn't it parallax?

Parallax. You can't get just one, they come as a pair.

isn;t that when you aren;t paying close enough attention, X2?

Many multimeter insturment companies in the 60's corrected for parallax by inserting a mirror on the meter face at full scale deflection of the insturment so you could line the needle up with itself. Clever, you no longer had to close one eye. ;)

a woodchuck would chuck all the wood that a woodchuck could chuck, if a woodchuck could chuck wood!!
