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?
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.
