What is the shift in the longitudinal center of gravity if 200 short tons are discharged from 30 feet forward of amidships on a MODU with LCG 1.5 feet forward of amidships, and displacement 9,000 short tons?

A 0.62 foot aft
B 0.65 foot aft
C 0.68 foot aft
D 0.71 foot aft
AI Explanation

The correct answer is B) 0.65 foot aft. The shift in the longitudinal center of gravity can be calculated using the formula: Shift in LCG = (Load Discharged x Distance from Amidships) / Displacement. In this case, 200 short tons are discharged from 30 feet forward of amidships on a MODU with an initial LCG of 1.5 feet forward of amidships and a displacement of 9,000 short tons. Plugging these values into the formula, we get a shift in LCG of 0.65 foot aft. The other options are incorrect because they do not accurately reflect the shift in LCG based on the given information.
