 Posted by: sblack ® 07/08/2005, 16:50:20 Author Profile Mail author Edit Hey, I'm preforming an engineering internship for the summer break and have ran into a design problem. I'm building a rack system to layer 1" solid steel bars. I need 60 1" bars per layer with multiple layers. I want to use standard black pipe for layering, and the pipe will be supported on both ends. Each individual 1" bar weighs 14lbs. The reason for wanting to use black pipe is due to weight, because the opporator will lift and hinge the pipe to get to the next layer. My concern is will 1" standard schedule 40 bend due to this weight? Keep in mind that there are two pipes assembled parallel and the 1" bars are laid across them. Thanks

Am I missing something??John
