Safety Factor: The ratio between breaking load and working load is known as the safety factor or design factor. For example, if a wire rope has a breaking load of 30,000 pounds and a working load limit of 6,000 pounds, the safety factor is 5:1. Calculation: To determine the working load limit, divide the breaking load by the safety factor.
