Quick Answer
To determine if your cordage is strong enough for use, pull on it with a consistent force until it breaks or shows signs of wear. Measure the breaking strength by comparing it to a known standard, such as a piece of twine or a cord. A minimum breaking strength of 20-30 pounds is recommended for many outdoor applications.
Testing Cordage Breaking Strength
When testing cordage breaking strength, it’s essential to use a consistent force and a controlled environment. Use a piece of equipment like a spring scale or a dynamometer to apply a steady load, and ensure the cord is securely attached to the device. For a more accurate reading, test multiple samples of cordage and take the average breaking strength.
Comparing Cordage Materials
Different cordage materials have varying breaking strengths. For example, a well-made piece of rawhide cordage can have a breaking strength of up to 500 pounds, while a well-twisted piece of plant fiber cordage may only have a breaking strength of 10-20 pounds. When creating cordage, consider the strength requirements of your application and choose materials accordingly.
Making Cordage for Specific Uses
When making cordage for specific uses, such as creating a fishing line or a tow rope, consider the forces that will be applied to it. For a fishing line, a breaking strength of at least 50 pounds is recommended, while a tow rope may require a breaking strength of 500 pounds or more. By creating cordage with a strength that matches its intended use, you can ensure it will perform safely and effectively.
