ON the cad offset the bend radius from the internal radius of the sheet metal part by 40% of the total sheet thickness,and measure the chord length of the radius. that will be the developed length.

According to United States Gypsum (www.usg.com), standard drywall weighs about 3.4 lbs per sq ft per inch thickness. Water resistant drywall (greenboard) weighs about 3.9 lbs. per sq. ft. per inch thickness. Firecode C drywall weighs about 4.2 lbs. per sq. ft. per inch thickness. These are approximations, as the ratio of core vs. covering varies for different thicknesses, thereby varying the exact weights. So, 1/2" thick standard drywall weighs 3.4 x 0.5, or 1.7 lbs per sq. ft. 4' x 8' x 1/2" thick sheet weighs 1.7 x 32 s.f. = 54 lbs. 4' x 10' x 1/2" thick sheet weighs 1.7 x 40 s.f. = 68 lbs. 4' x 12' x 1/2" thick sheet weighs 1.7 x 48 s.f. = 82 lbs. 5/8" thick standard drywall weighs 3.4 x 0.625 = 2.2 lbs per sq. ft. 4' x 8' x 5/8" thick sheet weighs about 70 lbs. 4' x 10' x 5/8" thick sheet weighs about 88 lbs. 4' x 12' x 5/8" thick sheet weighs about 105 lbs.
The gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.

It would remain 1mm thick.
4X8 sheet runs from about $40 - $50 for a standard sheet.
i am gona guess here, car windows are 3 laminates thick, i am referring to windshields, i think the " 40 " refers to either two of the 3 layers or all three before they are swandwiched together as each layer is 40 guage.But i could be wrong.
40 mm = 1.575 inches 40 mm = 4 cm

I'm not an expert, but I know that a thicker gauge is helpful for heavy metal music. .009's or .010's- Its all preference. The sound difference is almost undetectable. The thicker the gauge, the harder it is to bend and fret. I would go with .009's. Ive been playing most of my 40 years.
40 to 45 on the gauge. 40 is normal
