High performance material :-) High performance material :-) CoryPad (Materials) (OP) 16 Mar 15 17:34 I found an older drawing at work that I thought would be good for a few laughs. It appears that this part requires importation from Bespin. Check note 3 on the attached file. http://files.engineering.com/getfile.aspx?folder=9424dce5-3b62-4f18-a760-22 RE: High performance material :-) ewh (Aerospace) 16 Mar 15 18:47 Where would your vendor get the tibanna gas?

We have one note stating all dimension are in inches. We have another note (bottom right corner) stating all of the dimensions are in metric. (Maybe meters?) RE: High performance material :-) CoryPad (Materials) (OP) 17 Mar 15 01:02 Definitely inch measurements. I think the Metric note is part of a drawing template that was incorrectly chosen. Not a good drawing. RE: High performance material :-) mrfailure (Materials) 20 Mar 15 14:35 I've seen worse: one drawing I recently worked with called for tensile strength of a QT steel of 120 psi and yield of 95 psi. My definition of a non-structural steel! (While this may be an easy mistake to make the first time the drawing was prepared, there is no excuse for not catching it in th 4 subsequent revisions, including the one that added an alternate material with its own "psi" requirements).
