70% to pass

The DEEP DRILLER is moored in 600 feet of water. The tension on anchor line #8 is 190 kips. What is the vertical component of chain tension for that line?

A 53.6 long tons
B 55.3 long tons
C 84.8 long tons
D 442.4 long tons
AI Explanation

The correct answer is B) 55.3 long tons. To calculate the vertical component of chain tension, we need to use the formula: Vertical component = Tension × sin(θ), where θ is the angle between the anchor line and the seafloor. Given: - Water depth: 600 feet - Anchor line tension: 190 kips Since the anchor line is vertical, the angle θ is 90 degrees, and the sin(θ) is 1. Therefore, the vertical component of chain tension is: Vertical component = 190 kips × sin(90°) = 190 kips Conversion to long tons: 1 long ton = 2,240 pounds 190 kips = 190,000 pounds Vertical component = 190,000 pounds / 2,240 = 55.3 long tons The other answer choices are incorrect because: A) 53.6 long tons is too low C) 84.8 long tons is too high D) 442.4 long tons is significantly too high and does not match the given information.
