Multiple Choice

The design factor used to determine SWL is commonly what value?

Explanation:
The working load is set by applying a safety margin to the material’s breaking strength, so the equipment is used well below the point of failure. This margin, called the design factor, is commonly five. That means the safe working load is about one-fifth of the breaking strength. For example, if a piece of hardware has a breaking strength of 25,000 pounds, its SWL would typically be 5,000 pounds. Using a factor of five provides a practical balance between using the gear effectively and maintaining a strong safety cushion against dynamic loads, wear, and misuse. Other factors would change that margin, but five is the standard in many rigging and lifting contexts.
