With a safety factor of 15:1 accounted for, the actual usable capacity of the line is what?

Explanation:
The main idea is applying a safety factor to convert breaking strength into usable capacity. A safety factor of 15:1 means you divide the line’s breaking strength by 15 to get the working load limit. If the line’s breaking strength is 9000 pounds, then 9000 ÷ 15 equals 600 pounds. So the usable capacity is 600 pounds. The other numbers would result from using a different divisor or not applying the factor at all (9000 would be the breaking strength, not the usable load; 3000 would come from dividing by 3; 150 from a much larger divisor).
