What is the common arbitrary number used to determine the SWL?

Explanation:
SWL is the safe, allowable load you can apply to a line or component, not its ultimate breaking strength. To account for safety and uncertainties, engineers divide the maximum strength by a design factor to arrive at a conservative value. In many SLTC contexts, a design factor of 5 is the standard, so the SWL is one fifth of the breaking strength. This margin protects against dynamic loads, wear, environmental conditions, and human error, helping prevent overloading in real use. For example, if a component’s ultimate strength is 10,000 pounds, the SWL with a design factor of 5 would be 2,000 pounds.
