Question 1979 Deck General

The correct answer is A) 5,000 lbs. To determine the safe working load of a line, you need to divide the breaking strain by a safety factor. The safety factor is used to account for factors like wear, damage, and the dynamic forces acting on the line. For US Coast Guard Captain's License Examinations, a safety factor of 6 is typically used. Given that the breaking strain of the line is 30,000 lbs, and the safety factor is 6, the safe working load is calculated as 30,000 lbs / 6 = 5,000 lbs. This makes option A the correct answer. The other options are incorrect because they do not properly apply the safety factor of 6 to the breaking strain of 30,000 lbs.
