Question 4918Deck General70% to pass
A jack-up level at 12.5 feet draft transfers 100 kips of drill water from a tank with a TCG of -30 feet to a starboard tank with a TCG of 70 feet. The resulting starboard draft is 13 feet. The moment required to change list one inch (MCL1") is _______________.
AI Explanation
The correct answer is B) 833 foot-kips.
The explanation is as follows:
1. The question is asking for the moment required to change the list by one inch (MCL1"). This can be calculated using the formula: MCL1" = (100 kips) x (70 ft - (-30 ft)) / (13 ft - 12.5 ft) = 833 foot-kips.
2. The reasoning behind this is that the moment required to change the list by one inch is directly proportional to the weight transferred (100 kips) and the distance between the center of gravity of the tanks (70 ft - (-30 ft) = 100 ft), and inversely proportional to the change in draft (13 ft - 12.5 ft = 0.5 ft).
3. The other options are incorrect because they do not correctly apply the formula and calculation to the given information.
