This would imply that the stiffness of a rod is a forth power of its diameter so a sheet would be a square law on its thickness as sOlstice suggested.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-90329182361636081462007-04-14T10:13:00.000+01:002007-04-14T10:13:00.000+01:00Thanks sOlstice.

I have lots of offcuts of MDF with different thicknesses so I might have a go at measuring it some time and see if it fits a square law.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-3846776399733091722007-04-14T09:25:00.000+01:002007-04-14T09:25:00.000+01:00The senior mech eng at work says that when he was ...The senior mech eng at work says that when he was doing finite element analysis (admittedly some time ago), the stiffness depended on the square of the thickness. Googling for stiffness and thickness probably wouldn't help much ;->s0lsticehttps://www.blogger.com/profile/16394181379831072412noreply@blogger.com
