Could such a structure support a foom? A tiny house? Dors amyone know of s book or paper thT eould ensble one to determin how much weight such a structure will hold, and how this will vary with the strength of the struts and cable?<br /><br />In resdponding, you should assume I have a good working knowledge of linear algebra, a basic grasp of physics, but no engineering training. I would of course buy anengineering analysis before detting s spade to eatth.

One way you could determine forces in each member would be to splice in an axial spring of appropriate stiffness, and re-tension the structure. Note the distance the spring displaces, and you have your first internal force reading. Better yet- use a permanent marker to mark two points (separated by a known distance) before tensioning the structure. <BR/><BR/>Now you can determine the internal loads as: Force = E*A*deltaL/originalL, where E is the tensile elastic stiffness of your wire, and A is the x-sectional area of the wire. OriginalL is the original distance between the two markings you made on each wire. deltaL is simply the new distance minus the original.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-17776653.post-1158059586979145962006-09-12T13:13:00.000+02:002006-09-12T13:13:00.000+02:00Thanks, glad you like it.

The mathematics are a bit beyond me to be honest, fortunately is is fairly forgiving- I figured most of it out using small models and copying photographs of other people's work.Peter le Rouxhttps://www.blogger.com/profile/08442811474029232715noreply@blogger.comtag:blogger.com,1999:blog-17776653.post-1158055600807676312006-09-12T12:06:00.000+02:002006-09-12T12:06:00.000+02:00wow what a superb structure !!!!!!!!! what is the ...wow what a superb structure !!!!!!!!! what is the mathematical principle behind this tensegrityAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-17776653.post-1142303596450320612006-03-14T04:33:00.000+02:002006-03-14T04:33:00.000+02:00Absolutely stunning!
