I have a structure project to make a shade shelter, that includes using pipes to shape the structure. Only netting will be put on the structure, no other weight, Would pvc plastic pipes be too weak to support itself against wind and rain, if proper fittings and gluing agents are used? Of course I would not necessary expect it to stand up against hurricane or tornado type winds.
A decent pair of steel toe boots that cover your ankles, a pair of flexible leather gloves, and a leather jacket. You can ask at local motorcycle shops, ask other bikers, call your local ABATE chapter or just ask around where a good shop is to buy gear. Where I live is a locally owner business the sells bike related clothing and they are the best in town, provide great service, and have the best prices. I'm betting there is one in Nashville too.
use *plastic* scraper and some goof off 2 (yellow bottle) from Home depot or lowes.
The film serves as a non-reflective coating ( for certain wavelengths) by causing destructive interference between light reflected from it's upper and lower surface. Destructive interference occurs when the path difference between the combining waves is a half wavelength. Waves reflected at both surfaces suffer a ? wave phase change (as they both reflect off materials of greater refractive index) .. so the path difference is due to one set of waves having travelled further (ie through the film) For near normal incidence, this extra distance is 2d (d film thickness) The longest wavelength is given by .. 2d ? λ' .. (λ' wavelength in film [λ(air) / n]) .. So .. 2d ? [λ(air) / n] λ(air) 4dn .. .. 4(1.08^-7m)(1.31) .. .. ? λ(air) 5.66^-7 m (566 nm)
