Climbing Hold
A climbing hold is a shaped grip that is usually attached to a climbing wall so that climbers can grab or step on it. On most walls, climbing holds are arranged in paths called routes, by specially trained route setters. Climbing holds come in a large array of sizes and shapes to provide different levels of challenge to a climber. Holds are either bolted to a wall via hex-head bolts and existing t-nuts or they are screwed on with several small screws. In extreme cases, concrete anchors may be used (if putting holds on the underside of a bridge, for example). Early materials Rock In the early stages, climbing holds were crafted by casting real rocks into concrete blocks; later, they evolved into rocks with holes drilled into them, allowing attachment to a wall. While the feel of these holds is realistic, rock holds are heavy and can polish with heavy use. Rock holds are also difficult to manufacture. Wood Wood was another early hold-making material, mainly because it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The symbol , known in Unicode as hyphen-minus, is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash, so it is also used for these. The name ''hyphen-minus'' derives from the original ASCII standard, where it was called ''hyphen (minus)''. The character is referred to as a ''hyphen'', a ''minus sign'', or a ''dash'' according to the context where it is being used. Description In early typewriters and character encodings, a single key/code was almost always used for hyphen, minus, various dashes, and strikethrough, since they all have a similar appearance. The current Unicode Standard specifies distinct characters for several different dashes, an unambiguous minus sign (sometimes called the ''Unicode minus'') at code point U+2212, an unambiguous hyphen (sometimes called the ''Unicode hyphen'') at U+2010, the hyphen-minus at U+002D and a Hyphen#Unicode, variety of other hyphen symbols for v ...

Indoor Climbing
A climbing wall is an artificially constructed wall with manufactured grips (or "holds") for the hands and feet. Most walls are located indoors, and climbing on such walls is often termed indoor climbing. Some walls are brick or wooden constructions but on modern walls, the material most often used is a thick multiplex board with holes drilled into it. Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practice lead climbing or bouldering. Each hole contains a specially formed t-nut to allow modular climbing holds to be screwed onto the wall. With manufactured steel or aluminum walls, an engineered industrial fastener is used to secure climbing holds. The face of the multiplex board climbing surface is covered with textured products including concrete and paint or polyurethane loaded with sand. In addition to the textured surface and hand holds the wall may contain surface structures su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Competition Climbing
Competition climbing is a form of regulated rock climbing, rock-climbing competition held indoor climbing, indoors on purpose-built artificial climbing walls (earlier versions were held on external natural rock surfaces). The three competition climbing disciplines are lead climbing, bouldering, and speed climbing. The result of multiple disciplines can be used in a "combined" format to determine an all-round winner (or the "combined" winner). Competition climbing is sometimes called "sport climbing", which is the name given to bolt (climbing), pre-bolted lead climbing. In competition lead climbing, competitors start at the bottom of a bolt (climbing), pre-bolted sport climbing climbing routes, route and lead-climb to touch or secure the highest climbing hold possible within a set time limit on a single attempt, making sure to clip the rope into pre-placed quickdraws while ascending. In competition bouldering, competitors climb short bouldering problems without a rope, with an em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiberglass
Fiberglass (American English) or fibreglass (English in the Commonwealth of Nations, Commonwealth English) is a common type of fibre-reinforced plastic, fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic Matrix (composite), matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than Carbon-fiber-reinforced polymers, carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) is a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane term does not refer to the single type of polymer but a group of polymers. Unlike polyethylene and polystyrene, polyurethanes can be produced from a wide range of starting materials resulting in various polymers within the same group. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and polyurethane laminate (PUL). Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting a polymeric isocyanate with a polyol. Since a ...

Resin
A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, predominantly terpenes. Common resins include amber, hashish, frankincense, myrrh and the animal-derived resin, shellac. Resins are used in varnishes, adhesives, food additives, incenses and perfumes. Resins protect plants from insects and pathogens, and are secreted in response to injury. Resins repel herbivores, insects, and pathogens, while the volatile natural phenol, phenolic compounds may attract benefactors such as predators of insects that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-Pinene, alpha-pinene, pinene, beta-pinene, carene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and cad ...

Polyester
Polyester is a category of polymers that contain one or two ester linkages in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include some naturally occurring chemicals, such as those found in plants and insects. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind, and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for their mechanical propert ...

Campus Board
A campus board (or pan Güllich) is a training tool that has been widely adopted by sport climbing, sport climbers to improve their plyometric performance and led to dramatic improvements in climbing technique in all rock climbing disciplines. The campus board was invented in 1988 by German climber Wolfgang Güllich to help him climb the world's hardest consensus-graded route at the time, ''Action Directe (climb), Action Directe'', and has since become a standard training tool for climbers. Other climbing training 'boards' have been developed since the campus board, including the MoonBoard, a small customized overhanging indoor climbing wall also for plyometric performance, and the hangboard (or also the fingerboard), a device for building up static strength, particularly in the fingers, but also in the arms. Description Typically, a user ascends or descends the campus board using only their hands, and often leaping from hold to hold (i.e both hands are off the board while transit ...
