I doubt it, though I'm not even sure what "electron dressing" is. I was simply referring to the fact that a weight at the end of a lever is multiplied by the lever factor. The lever in this case is the Pd plate itself. The top surface is stretched and the bottom surface is compressed. The leverage at any point is the distance from that point to the center of mass of the weight divided by the thickness at that point. On average, it will be half the length divided by the thickness. The degree to which bending occurs will depend on the extent to which the lattice structure is locally weakened by the absorbed H. > >-----Original Message----- >From: [email protected] [mailto:[email protected]] >Sent: Friday, November 19, 2010 9:00 PM >To: [email protected] >Subject: EXTERNAL: Re: [Vo]:Pd - quasi-liquid > >In reply to Jones Beene's message of Fri, 19 Nov 2010 16:30:51 -0800: >Hi, >[snip] >>http://www.technologyreview.com/blog/arxiv/26046/ > >They note that vertical stretching is minimal when the same weight is used. >Well >Duh!, when it's horizontal, the weight of the load is leveraged to a huge >degree >(about half the length divided by the thickness), while not at all when it is >hung vertically. >Regards, > >Robin van Spaandonk > >http://rvanspaa.freehostia.com/Project.html Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
