Making a rope very tight, such as to secure an object to a vehicle. Caveat. Can produce excessive wear on rope, especially if tied repeatedly in the same spot [6] ABoK. #1514, #2124, #2125, #2126. Instructions. [1] The trucker's hitch is a compound knot commonly used for securing loads on trucks [7] or trailers.
The cow hitch, also called the lark's head, is a hitch knot used to attach a rope to an object. The cow hitch comprises a pair of single hitches tied in opposing directions, as compared to the clove hitch in which the single hitches are tied in the same direction. It has several variations and is known under a variety of names.
Constrictor knot. The constrictor knot is one of the most effective binding knots. [1][2][3][4] Simple and secure, it is a harsh knot that can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn.
A knot diagram with crossings labelled for a Dowker sequence. In the mathematical field of knot theory, the Dowker–Thistlethwaite (DT) notation or code, for a knot is a sequence of even integers. The notation is named after Clifford Hugh Dowker and Morwen Thistlethwaite, who refined a notation originally due to Peter Guthrie Tait.
Reidemeister move. In the mathematical area of knot theory, a Reidemeister move is any of three local moves on a link diagram. Kurt Reidemeister (1927) and, independently, James Waddell Alexander and Garland Baird Briggs (1926), demonstrated that two knot diagrams belonging to the same knot, up to planar isotopy, can be related by a sequence of ...
In the mathematical field of knot theory, Fox n-coloring is a method of specifying a representation of a knot group or a group of a link (not to be confused with a link group) onto the dihedral group of order n where n is an odd integer by coloring arcs in a link diagram (the representation itself is also often called a Fox n -coloring).
Instructions. [1] A Matthew Walker knot is a decorative knot that is used to keep the end of a rope from fraying. It is tied by unraveling the strands of a twisted rope, knotting the strands together, then laying up the strands together again. It may also be tied using several separate cords, in which case it keeps the cords together in a bundle.
A tricky unknot diagram by Morwen Thistlethwaite. In mathematics, the unknotting problem is the problem of algorithmically recognizing the unknot, given some representation of a knot, e.g., a knot diagram. There are several types of unknotting algorithms. A major unresolved challenge is to determine if the problem admits a polynomial time ...
