View Full Version : Math expert needed

Some days I am not in the thinking mood.

If I need an area cut out of a larger piece of material but turned on a 45, how big does the larger piece need to be? What I want is to cut a 12"x30" piece out of a sheet of wire mesh. They only sell it in 90 degree sheets. My piece needs to be turned on a 45 (diamonds instead of squares).

I know the cosine of 45 is .707
I need a 12" x 30"
I forgot the rest...

So you're trying to cut the red rectangle out of the black square? You need at least 30" x 30" to get the shape I show there. My rectangle is dimensionally correct for 12" x 30", so if I assume the hypotenuse of one of the black squares is 6", then 6*cos(45) = 4.24, so each of the black squares is 4.24 on each side. There are 7 x 7 to fit your shape inside, so that's just under 30" x 30". HTH?

perfect! I didn't think of laying out the hypotenuse to equal 12". That is exactly what I needed. Thank you

2nd question....does anyone know of a local source for metal mesh? I have exhausted all my online retailers.

is :cool:

I was wondering why your grille still was empty last Wednesday, I was like, "get on it!" ;)

what are you doing with the rest of your mesh?

Thank you. Terry, you are welcome to what is left over if you wanted it.

That's becoming a popular mod on the new Tacomas as well.
