What is the decrease in longitudinal moments for the Deep Driller if 2.0 feet of ballast is transferred from 1S to 10P?

A 15,265 ft-tons
B 14,609 ft-tons
C 7,293 ft-tons
D 5,174 ft-tons
AI Explanation

The correct answer is B) 14,609 ft-tons. The decrease in longitudinal moments when 2.0 feet of ballast is transferred from 1S to 10P is 14,609 ft-tons. This is because moving ballast weight from a forward location (1S) to an aft location (10P) will reduce the longitudinal moment, as the moment arm for the aft location is larger. The calculation takes into account the weight of the ballast and the change in moment arm to determine the overall decrease in longitudinal moment. The other options are incorrect because they do not accurately reflect the change in longitudinal moment due to the ballast transfer. Option A is too high, Option C is too low, and Option D is also too low compared to the correct answer.
