A MODU displacing 29,500 long tons has a KG of 60 feet. A weight of 500 long tons is added at a VCG of 150 feet. What is the change in KG?
AI Explanation
The correct answer is C) 1.5 feet upward.
To calculate the change in KG, we can use the formula: KG_new = (KG_old * Displacement_old + VCG_new * Weight_added) / (Displacement_old + Weight_added).
Given:
- MODU displacement: 29,500 long tons
- Original KG: 60 feet
- Added weight: 500 long tons
- VCG of added weight: 150 feet
Plugging in the values, we get:
KG_new = (60 * 29,500 + 150 * 500) / (29,500 + 500) = 61.5 feet
The change in KG is the difference between the new KG and the original KG, which is 1.5 feet upward. This makes option C the correct answer.
The other options are incorrect because they do not accurately reflect the change in KG based on the given information.
