String (structure)
[1] In Mesoamerica, for example, string was invented some 20,000 to 30,000 years ago, and was made by twisting plant fibers together.
String, along with twine and other cordage, was used in prehistoric times for hafting sharp stone tips onto spears, in beadwork, to ease firelighting (as part of a bow drill, as well as for fishing lines and nets, clothing, shelter-making materials, bow string, sutures, traps, and countless other uses.
Similar drills were found in other parts of the Indus Valley civilization and Iran one millennium later.
Natural fibres used for making twine include cotton, sisal, jute, hemp, henequen, and coir.
Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, and ropemaking.
Heavy goods that must withstand considerable stresses such as upholstery, car seating, tarpaulins, tents, and saddlery require very strong threads.
More generally and commonly, a pullstring can be any type of string, cord, rope, chain, or cable attached to an object in some way used to pull or mechanically manipulate part of it.
They typically consist of a pair of strings or cords, one for each shoe, finished off at both ends with stiff sections, known as aglets.
Each shoelace typically passes through a series of holes, eyelets, loops or hooks on either side of the shoe.
Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably.
This is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility for playability.
A textile[9] or cloth[10] is a flexible material consisting of a network of natural or artificial fibres (yarn or thread).
Washing lines are attached either from a post or a wall, and are frequently located in back gardens, or on balconies.
Longer washing lines often have props holding up sections in the middle due to the weight of the usually wet clothing.
It may consist of a length of one or several segments of string, twine, cord, strap, rope, or even chain interwoven such that the line can bind to itself or to some other object (the "load").
It was long crafted by sailors, especially in elaborate or ornamental knotting forms, to decorate anything from knife handles to bottles to parts of ships.
A plumb bob, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line.
Thread, wire, or string is wound around a grid of nails hammered into a velvet-covered wooden board.
The metal weight lowers the moment of inertia of the center ball so it can rotate rapidly in response to torques applied by the string.
It is played by holding the free end of the string known as the handle (usually by inserting one finger into a slip knot) allowing gravity or the force of a throw to spin the yo-yo and unwind the string (similar to how a pullstring works), then allowing the yo-yo to wind itself back to one's hand, exploiting its spin (and the associated rotational energy).
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth.
