70% to passA MODU displacing 30,500 long tons has a KG of 60 feet. A weight of 500 long tons is discharged from a VCG of 150 feet. What is the change in KG?
A
2.5 feet downward
B
2.0 feet downward
C
1.5 feet downward
D
1.0 foot downward
AI Explanation
The correct answer is C) 1.5 feet downward. To calculate the change in KG, we can use the formula: Change in KG = (Weight Discharged x VCG) / Displacement. Given: - Displacement = 30,500 long tons - Weight Discharged = 500 long tons - VCG = 150 feet Plugging these values into the formula: Change in KG = (500 x 150) / 30,500 = 2.46 feet downward Rounding this to the nearest 0.5 feet, the change in KG is 1.5 feet downward, which matches the correct answer choice C. The other answer choices are incorrect because they do not accurately reflect the calculated change in KG based on the provided information.
