VTmotoMike08 0 #27 July 3, 2008 Quote ok i have a question that has me wondering...... if you have a canopy that has a continuous a/b line ,how much load (theoretical) would those 2 lines hold before breaking? in other words, if you have an A suspension line made of say 600lb material(vectran spectra whatever) that attaches to the A line attach point on the canopy,then runs down thru the connector link then back up to the B l.a.p.,would it be able to take 1200 lbs? or would it break at 600? In the given configuration, assuming no wear at the link (which acts like a pully), it would break at 1200 lbs. I have taken that simple course it statics so here goes: Draw a Free Body Diagram around the link, passing thru the line. You can then see that the diagram cuts the given lines in two locations. So, it would support twice the 600 lb weight. However, in a real system, the friction at the link would not be negligible, so this must be examined. Obviously, a smoother surface on the link would be better than a rough one. Anyway, a "floating" A-B line (as I am understanding it" really sounds like a bad idea to my non-rigger ears. Feel free to correct. Quote Share this post Link to post Share on other sites
