Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural or synthetic fibres. [1] [2] [3] Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be ...
Sterculia villosa, the hairy sterculia, or elephant rope tree, known vernacularly as Sardol, Udal, or Udar in Northeast India, is a medium-sized, monoecious tree. A leaf from this plant is characterized by a petiole about 25–40 cm long and by a lamina composed of 5-7-lobes, approximately 20–40 cm long and wide.
In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
Branch attachment in common ash Fraxinus excelsior L. Figure 1: Anatomical drawing of the wood grain of a branch attachment in a tree. Initially branches are mechanically attached to the trunks of trees by forming interlocking wood grain patterns at the top of the joint, within what is known as 'axillary wood' (Fig. 1). [1]
A mnemonic used to teach the tying of the bowline is to imagine the working end of the rope as a rabbit. 1,2 – a loop is made into the standing part which will act as the rabbit's hole; 3 – the "rabbit" comes up the hole, 4 – goes round the tree (standing part) right to left; 5 – and back down the hole
Growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions. [6] The vine growth form may also enable plants to colonize large areas quickly, even without climbing high. This is the case with periwinkle and ground ivy. It is also an adaptation to life in areas where small patches of fertile soil are ...

For example, rope used in caving is generally exposed to increased abrasion, so the mantle is woven more tightly than rope used in climbing or rappelling. However, the resulting rope is cumbersome and difficult to tie knots in. Kernmantle construction may be used for both static and dynamic ropes. Static ropes are designed to allow relatively ...
