⭐ Core Definition: Rope

A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have high tensile strength and can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, string, and twine.

Rope in the context of Papyrus

Papyrus (/pəˈprəs/ pə-PY-rəs) is a material similar to thick paper that was used in ancient times as a writing material. It was made from the pith of the papyrus plant, Cyperus papyrus, a wetland sedge. Papyrus (plural: papyri or papyruses) can also refer to a document written on sheets of such material, joined side by side and rolled up into a scroll, an early form of a book.

Papyrus was first known to have been used in Egypt (at least as far back as the First Dynasty), as the papyrus plant was once abundant across the Nile Delta. It was also used throughout the Mediterranean region. Apart from writing material, ancient Egyptians employed papyrus in the construction of other artifacts, such as reed boats, mats, rope, sandals, and baskets.

Rope in the context of Block and tackle

A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, used to provide tension and lift heavy loads.

The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load. The rope is threaded through the pulleys to provide mechanical advantage that amplifies the force applied to the rope.

Rope in the context of Tent

A tent is a shelter consisting of sheets of fabric or other material draped over or attached to a frame of poles or a supporting rope. While smaller tents may be free-standing or attached to the ground, large tents are usually anchored using guy ropes tied to stakes or tent pegs. First used as portable homes by nomads, tents are now more often used for recreational camping and as temporary shelters.

Tents range in size from "bivouac" structures, just big enough for one person to sleep in, up to huge circus tents capable of seating thousands of people. Tents for recreational camping fall into two categories. Tents intended to be carried by backpackers are the smallest and lightest type. Small tents may be sufficiently light that they can be carried for long distances on a touring bicycle, a boat, or when backpacking. The second type are larger, heavier tents which are usually carried in a car or other vehicle. Depending on tent size and the experience of the person or people involved, such tents can usually be assembled (pitched) in between 5 and 25 minutes; disassembly (striking) takes a similar length of time. Some very specialised tents have spring-loaded poles and can be pitched in seconds, but take somewhat longer to strike (take down and pack).

Rope in the context of Yarn

Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses (referred to as "weights"). Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue.

Rope in the context of Rag paper

Rag paper is a category of paper that is made from a pulp of discarded textiles, rope and other fibre products. Rag paper in its various forms was a widely-used paper for most of the past two millennia. Production spread along the Silk Road from its early 2nd-century origin in China to the Islamic world by the 8th century. It was introduced into Christian Europe by the 12th century, and western Europe came to dominate rag production up until the mid-19th century, when rag paper was displaced in favour of far more cost-efficient pulpwood acidic paper.

Rag paper is valued today as a specialty paper for its archival quality and tear resistance compared to wood pulp paper. Modern rag paper is often cotton paper, made from cotton linters, with a usual pH of 6.4 and degree of polymerization of 1481.2.

Rope in the context of Hemp

Hemp, or industrial hemp, is a plant in the botanical class of Cannabis sativa cultivars grown specifically for industrial and consumable use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.

Although chemotype I cannabis and hemp (types II, III, IV, V) are both Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the psychoactive effects of THC. The legality of hemp varies widely among countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content into commercial production.

Rope in the context of Wire rope

Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite rope, in a pattern known as laid rope. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as cable laid. Manufactured using an industrial machine known as a strander, the wires are fed through a series of barrels and spun into their final composite orientation.

In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (38 in), with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes.

Rope in the context of Pulleys

A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself and a shaft.

A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain.

Rope in the context of Clothes line

A clothes line, also spelled clothesline, also known as a wash line, is a device for hanging clothes on for the purpose of drying or airing out the articles. It is made of any type of rope, cord, wire, or twine that has been stretched between two points (e.g. two posts), outdoors or indoors, above ground level. 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 the mid-section so the weight of the clothing does not pull the clothesline down to the ground.

Clothing that has recently been washed is hung over the line to dry. Nowadays it is held in place with clothespins, but until the 19th century laundry was simply draped over the line (and often blew away), as is visible in artistic depictions of clotheslines from earlier periods. The clothespin was not invented until 1809.
