A turnbuckle is a device for adjusting the tension or length of ropes, cables and tie rods. A rope is a length of Fibers twisted or Braided together to improve strength for pulling and Connecting. A cable is one or more Wires or Optical fibers bound together typically in a common protective jacket or sheath A tie rod is a slender structural rod used as a tie and (in most applications capable of carrying tensile loads only It normally consists of two threaded eyelets, one screwed into each end of a small metal loop, one with a left-hand thread and the other with a right-hand thread. A screw thread is a helical or tapered structure used to convert between rotational and linear movement or force Look up SpecialSearch/{{lcscrew}}}}}|{{{2|{{{1|screw}}}}}} The tension can be adjusted by rotating the loop, which causes both eyelets to be screwed in or out simultaneously. In Physics String Tension is the magnitude of the pulling force exerted by a string cable chain or similar object on another object Turnbuckles are most commonly used in applications which require a great deal of tension; they can range in mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges. For other uses of the words gram or gramme see Gram (disambiguation. A fence is a freestanding structure designed to restrict or prevent movement across a boundary This article is concerned with a particular type of suspension bridge the suspended-deck type This device is also known as a bottlescrew and is used on ships for tensioning rigging and lashings.
