Just curiuous, how did you attempt to solve Joe Nations problem? Could you show us what steps you took?

I'm not about to solve Joe's problem because it makes no sense...
Who makes a bracket that is 5/8" thick?
For that matter who makes a stud that is 1-3/4" thick?
I think Joe needs to spend more time at Home Depot and less time doing math problems.

Besides realjohnboy I can't imagine that anyone here spends more time in a homedepot
(I suppose, Joe even spends more time in there, since johnboy sometimes drives from one to the other. :wink: )

It's impossible for Americans to solve the following:

Joe(take your time)Nation
1/2"= 12.7 mm
5/8"= 15.875 mm
1 3/4"= 44.45 mm (btw, it's a unit for electronic racks' height).
(1 3/4")/2= 22.225 mm
The lenght of the screw= 12.7+15.875+22.225= 50.8 mm = 2 inches.
noooooo.......2 and 7/8's
You can put your dental floss in a small box instead of on the screw...
Arrggghh!
I was adding in the entire 1 and 3/4's wasn't I?
Drat!
and joe nation told me I was right.
wow joe, good catch.
Chai(double check your math)Tea
oh c'mon....it was near my bedtime when I tried to solve it the first time.
At least I see where I made my mistake.

That's 6.35 kg kicked as far as nearly 5 feet. Wow!
If I kicked a 14 pound rock, I'd have a broken foot!
Let's spare Walter the rod and give him a hand.
I can't begin to fathom how he knew how much mass a stone has but then he is probably in a league with the devil.

OK you math fiends, you've been having so much fun with the math questions, try this one:
To move their armies, the Romans built over 50,000 miles of roads. Imagine driving all those miles! Now imagine driving those miles in the first gasoline-driven car that has only three wheels and could reach a top speed of about 10 miles per hour.
For safety's sake, let's bring along a spare tire. As you drive the 50,000 miles, you rotate the spare with the other tires so that all four tires get the same amount of wear. Can you figure out how many miles of wear each tire accumulates?
each tire is used 3/4's of the time.
50,000 x .75 = the sign of the beast.
Kitchen cups
Have you ever seen the written form of the Sanskrit language? If so, you probably are amazed at how different this ancient language from India looks from ours. Some English words, however, are based on Sanskrit. For example, cup comes from the Sanskrit work kupo, which means water well. This puzzle requires several water wells.

Suppose you need to measure exactly 1 cup of water. All that you have in your kitchen are two containers. The smaller container holds 3 cups and the larger holds 5 cups. How can you use these two containers to measure exactly 1 cup of water?
1- fill the 5cc (cup container).
2- Pour into the 3cc.
3- It leaves you 2 cups in the 5cc
4- Empty the 3cc
5- Pour the 2 cups left in the 5cc into the 3cc
6- Refill the 5cc.
7- Pour one more cup in the 3cc.
8- Four cups are left in the 5cc...
oh come on....
come up with something hard.
it's easier than that francis....
fill the 3 cup and pour into the 5
fill the 3 cup again and pour as much as you can into the 5
you're left with 1 cup in the 3 cup container.
Wow. You guys are like totally numerological, y'know? I'm, like, totally impressed. (Whoever it was that asked about whoever saw an inch and three-quarters stud -- take a tape measure to a two-by-four. The "two" ain't no two inches.)
