Quick Answer
The diameter of cordage directly affects its load-bearing capacity, with larger diameters generally able to support heavier loads. A common rule of thumb is that cordage should be at least 1/8 inch in diameter to support loads safely. However, the actual load-bearing capacity also depends on the type of material and how it's used.
Understanding Cordage Load-Bearing Capacity
When it comes to cordage, the diameter is just one factor that affects its load-bearing capacity. The material itself, such as the type of plant fibers used or the thickness of the cordage, also plays a significant role. For example, a 1/8 inch diameter cordage made from a strong plant like nettle can support up to 200 pounds, while a similar diameter cordage made from a weaker plant like cattail might only support 100 pounds.
The Reverse Wrap Technique
The reverse wrap technique is a method used to calculate the maximum load a cordage can support based on its diameter. To use this technique, you’ll need a ruler and a piece of cordage. Wrap the cordage around a cylindrical object, such as a pencil, and mark the point where it overlaps. Measure the diameter of the cordage at this point and use a table or chart to determine the maximum load it can support. For example, if the diameter is 1/8 inch, the reverse wrap technique might indicate a maximum load of 200 pounds. However, keep in mind that this is just an estimate and actual load-bearing capacity may vary depending on the specific cordage and conditions.
