Rope making

Rope making uses a set of long stringy, fibrous material. They are generally the same length and same material to get the correct rope type. Each rope is stronger than material as twine, string, or cord.
Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Ropes have been constructed of other fibrous materials such as silk, wool, and hair, but such ropes are not generally available. The twist of the strands in a twisted or braided rope serves not only to keep a rope together, but enables the rope to more evenly distribute tension among the individual strands. Without any twist in the rope, the shortest strand(s) would always be supporting a much higher proportion of the total load.
The long history of rope means that many systems have been used to state the size of a rope. In systems that use the "inch" , large ropes over 1 inch (25.4 mm) diameter such as are used on ships are measured by their circumference in inches; smaller ropes have a nominal diameter based on the circumference divided by three (rounded-down value for pi). In metric systems of measurement, nominal diameter is given in millimetres. The current preferred international standard for rope sizes is to give the mass per unit length, in kilograms per metre. However, even sources otherwise using metric units may still give a "rope number" for large ropes, which is the circumference in inches.
