Sounds good, but I’m not sure how to word it. Stainless (Pure Sound) is MUCH more malleable, but how can we measure it or quantify it, and what would that mean for the technician? Just searching for a good Q. Also, when using stainless you need to handle it a bit differently. You can’t “force” it around the hitch to make your beckets line up. I guess that’s what you’re asking?<o:p></o:p> <o:p> </o:p> Thanks,<o:p></o:p> <o:p> </o:p> Jim Busby BYU<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On Behalf Of Daniel Gurnee Sent: Monday, August 27, 2007 3:29 PM To: <st1:PersonName w:st="on">College and University Technicians</st1:PersonName> Subject: Re: [CAUT] Scientific study - Stainless wire (Help!)<o:p></o:p> </div> <o:p> </o:p> <div> Good going and wishing well the project.<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Compare breaking strength.<o:p></o:p> </div> <div> Compare malleability.<o:p></o:p> </div> <div> Compare fracture time with working.<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Daniel Gurnee, RPT, HSU Retired<o:p></o:p> </div> <o:p> </o:p> <div> <div> On Aug 27, 2007, at 2:09 PM, Jim Busby wrote:<o:p></o:p> </div> <o:p></o:p> <div> List,<O:P style="font-family: Arial; font-size: 13.3333px; "></O:P><o:p></o:p> <O:P style="font-family: Arial; font-size: 13.3333px; "> </O:P><o:p></o:p> We (BYU) finally are ready to do some scientific studies of stainless wire.
