A knot is a method for fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or more segments of rope, cord, webbing, twine , string, strap or even chain interwoven so as to create in the line the ability to bind to itself or to some other object - the "load". Some knots are well adapted to bind to particular objects such as another rope, cleatFittings on ships and boats that ropes are tied to: often shaped like horns, although other types exist., ring, stake or to constrict an object. Decorative knots usually bind to themselves to produce attractive patterns.
Knots have been the subject of interest both for their ancient origins, common use or the mathematical implications of knot theoryKnot theory is a branch of topology that was inspired by observations, as the name suggests, of knots. But progress in the field no longer depends on experiments with twine. Knot theory concerns itself with abstract properties of theoretical knots--the sp.
Knots are essential in many industrial, work, home or recreational activities. Even simple activities such as running a load from the hardware store to home can result in disaster if a clumsy twist in a cord passes for a knot. Truckers needing to tie down a load may use a trucker's hitchThe trucker's hitch is a self-binding knot commonly used for securing loads on trucks or trailers. Canonical Name trucker's hitch. Variant Name(s) None. Category binding. Origin Ancient. Related knots Releasing Non-jamming. Efficiency Unknown. Caveat None, gaining a 2-to-1 mechanical advantageIn physics and engineering mechanical advantage (MA is the factor by which a machine multiplies the force put into it. The mechanical advantage can be calculated for the following simple machines by using the following formulas: Lever: MA length of effort. Knots can save the spelunker from foolishly becoming buried under millions of tons of rock. Whatever the activity, on the water sailingSailing is motion across a body of water in a sailing ship, or smaller boat, powered by wind. How sailing works The force of the wind is used to create motion by using one or more sails. The movement of the air over the sails acts in the same way that air or on a cliff-side rock climbingthe Roaches. Climbing is going up, or, depending on context, also down. It may refer to aircraft, a land vehicle, and humans and animals. On land, in particular it refers to steep climbs, e. on a hill, mountain or stairs, in a pole or tree, etc. This arti, learning well tested knots prior to some hazardous activity introduces a critical measure of safety. In addition to safety, appropriate knots can prevent the necessity of cutting lines.
Many types of textiles use knots to repair damage. One form of textiles, macrame is generated exclusively through the use of knotting, instead of knits, crochets, weaves or felting. Macrame can produce self-supporting three dimensional textile structures, as well as flat work, and is often used ornamentally or decoratively.
