Sheep Shank
A shank is a type of knot that is used to shorten a rope or take up slack, such as the sheepshank. The sheepshank knot is not stable. It will fall apart under too much load or too little load. The knot has several features which allow a rope to be shortened: * It provides two loops, one at each end of the knot which can be used to pass another rope through * The knot remains somewhat secure under tension; the coarser the rope the more secure it is (see Disadvantages, below) * The knot falls apart easily when tension is removed Construction methods A sheepshank knot may be constructed as follows: ... * Pull a section of rope back and lay it alongside the rope, so that the rope forms a Z approximately 20 cm long. * Flatten the Z so that there are 3 sections of rope lying alongside each other, with two U-bends where the rope reverses direction. * At each U-bend, grasp the U-bend in one hand, thus holding two of the rope sections. With the other hand form a small loop in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kamikaze
, officially , were a part of the Japanese Special Attack Units of military aviators who flew suicide attacks for the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, intending to destroy warships more effectively than with conventional air attacks. About 3,800 ''kamikaze'' pilots died during the war, and more than 7,000 naval personnel were killed by ''kamikaze'' attacks. ''Kamikaze'' aircraft were essentially pilot-guided explosive missiles, purpose-built or converted from conventional aircraft. Pilots would attempt to crash their aircraft into enemy ships in what was called a "body attack" (''tai-atari'') in aircraft loaded with bombs, torpedoes and or other explosives. About 19% of ''kamikaze'' attacks were successful. The Japanese considered the goal of damaging or sinking large numbers of Allied ships to be a just reason for suicide attacks; ''kamikaze'' was more accurate than conventional attacks and often cau ...

Coil Knot
A coiling or coil is a curve In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. Intuitively, a curve may be thought of as the trace left by a moving point. This is the definition that ..., helix, or spiral used for storing rope or Wire rope, cable in compact and reliable yet easily attainable form. They are often discussed with knots. Mountaineer's coil The mountaineer's coil (also alpine coil, climber's coil, lap coil, or standing coil) is a traditional method used by climbing, climbers to store and transport a climbing rope. This older style coil is noted as being more prone to twists and tangles than the #Butterfly_coil, butterfly coil, and care must be taken upon uncoiling to avoid these problems. Tying method Begin by taking hold of the rope in one hand with its end facing you. Coil the rope in arm's length sections with your free hand (extending it away from the other as far ...

Bowline
The bowline ( or ) is an ancient and simple knot used to form a fixed loop at the end of a rope. It has the virtues of being both easy to tie and untie; most notably, it is easy to untie after being subjected to a load. The bowline is sometimes referred to as ''King of the knots'' because of its importance. Along with the sheet bend and the clove hitch, the bowline is often considered one of the most essential knots. The common bowline shares some structural similarity with the sheet bend. Virtually all end-to-end joining knots (i.e., bends) have a corresponding loop knot. Although the bowline is generally considered a reliable knot, its main deficiencies are a tendency to work loose when not under load (or under cyclic loading), to slip when pulled sideways, and the bight portion of the knot to capsize in certain circumstances. To address these shortcomings, a number of more secure variations of the bowline have been developed for use in safety-critical applications, or by s ...

Bight (knot)
In knot tying, a bight is a curved section or slack part between the two ends of a rope, string, or yarn.. "Any slack part of a rope between the two ends, particularly when curved or looped." A knot that can be tied using only the bight of a rope, without access to the ends, is described as in the bight. The term "bight" is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot. Bight vs. open loop Sources differ on whether an open loop or U-shaped curve in a rope qualifies as a bight. treats bights and loops as distinct, stating that a curve "no narrower than a semicircle" is a bight, while an open loop is a curve "narrower than a bight but with separated ends". However, ''The Illustrated Encyclopedia of Knots'' (2002) states: "Any section of line that is bent into a U-shape is a bight." Slipped knot In order to make a slipped knot (also slipped loop and quick release knot), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhand Knot
The overhand knot is one of the most fundamental knots, and it forms the basis of many others, including the simple noose, overhand loop, angler's loop, reef knot, fisherman's knot, Half hitch, and water knot. The overhand knot is a stopper, especially when used alone, and hence it is very secure, to the point of jamming badly. It should be used if the knot is intended to be permanent. It is often used to prevent the end of a rope from unraveling. An overhand knot becomes a trefoil knot, a true knot in the mathematical sense, by joining the ends. It can also be adjusted, faired, or mis-tied as a half hitch Tying There are a number of ways to tie the Overhand knot. * Thumb method – create a loop and push the working end through the loop with your thumb. * Overhand method – create a bight, by twisting the hand over at the wrist and sticking your hand in the hole, pinch the working end with your fingers and pull through the loop. Heraldry In heraldry, the overhand knot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rappelling
Abseiling ( ; ), also known as rappelling ( ; ), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling the person descending controls their own movement down the rope, in contrast to lowering off in which the rope attached to the person descending is paid out by their belayer. This technique is used by climbers, mountaineers, cavers, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep and/or dangerous to descend without protection. Many climbers use this technique to protect established anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to the point where it can be controlled comfortably. These techniques range f ...

Man Vs
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional gender roles have often defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
