V závěru lze říci, že drátěné pletivo, nebo bulk chicken wire, je skvělým pomocníkem v mnoha oblastech, od zahradnictví po design. Jeho univerzálnost, odolnost a cenová dostupnost z něj činí ideální volbu pro každého, kdo hledá efektivní a spolehlivé řešení pro ochranu a výstavbu. Ať už jste zkušený zahradník, farmář nebo jen nadšenec do zahradničení, drátěné pletivo by mělo být součástí vašeho nářadí.
An extension spring, also referred to as a tension spring, realizes its energy potential from the tension that occurs when it is stretched, pulled or elongated. Unlike compression springs, the coils of an extension spring are tightly wound and contact each other. The tighter the coils are, the greater resistance and tensile force when pulled.
When helical springs are compressed and extended, end-to-end twisting occurs. Three remedies exist with machined springs to eliminate the torsional deformation. Fix the end of the spring using any of the attachment techniques available. Or, constrain the spring end to increase the elastic rate. Or, use two concentric springs one with a right hand flexure and the other a left hand. When properly designed, the twisting of the inner spring counteracts that of the outer one. An option is to place two flexures on a single spring blank, one right hand and the other left hand. This configuration allows the interface between the two flexures to twist, but the ends do not.
