Can I tie a knot on a foot-long rope that is one inch thick? In terms of ropelength, this asks if there is a knot with ropelength 12 {\displaystyle 12} . The answer is no: an argument using quadrisecants shows that the ropelength of any nontrivial knot has to be at least 15.66 {\displaystyle 15.66} . [ 1 ]
Knotted cords were used by rope stretchers, royal surveyors who measured out the sides of fields (Egyptian 3ht). The knotted cords (Egyptian ht) were 100 royal cubits in length, with a knot every hayt or 10 royal cubits. The rope stretchers stretched the rope in order to take the sag out, as well as to keep the measures uniform.
The Byzantine equivalent, the schoinion or "little rope", varied between 60 and 72 Greek feet depending upon the location. The Thai sen of 20 Thai fathoms or 40 m also means and is translated "rope". The Somerset rope was a former English unit used in drainage and hedging. It was 20 feet (now precisely 6.096 m). [1] [2]
The length of these fids is typically 21 or 22 times the diameter of rope to be spliced. A one-half-inch (12.7 mm) diameter rope would have any accompanying fid 10.5–11 in (266.7–279.4 mm) in length with hash-marks denoting the long and short fid measurements. A short fid is 1 ⁄ 3 a fid length and a long fid is 2 ⁄ 3 the overall fid length.
