What minimum size manila line is required to hold a weight of 932 pounds, if you use a safety factor of six?

Correct Answer: Option B — 2.5"

The breaking strength required is 932 lbs multiplied by a safety factor of 6, totaling 5,592 lbs. Using the formula for manila line strength (Breaking Strength = 900 x circumference squared), a 2.5-inch line provides approximately 5,625 lbs of strength, which is the minimum size required to exceed the load.
