112. What minimum size manila line is required to hold a weight of 932 pounds, if you use a safety factor of six?
The required breaking strength is calculated by multiplying the load by the safety factor (932 lb x 6 = 5592 lb). Using the formula breaking strength ≈ 900 x circumference2, a 2.5-inch line provides a breaking strength of 5625 lb, resulting in a safe working load exceeding the required 932 lb. Therefore, 2.5 inches is the minimum acceptable size.
