70% to pass

An elevated jack-up weighs 14,000 kips. The drill floor, weighing 700 kips, is skidded 10.0 feet to starboard. The change in TCG is _______________.

A 9.00 feet starboard
B 0.50 foot starboard
C 1.50 foot starboard
D 1.00 foot starboard
AI Explanation

The correct answer is B) 0.50 foot starboard. The change in TCG (Transverse Center of Gravity) is calculated by multiplying the weight of the moved object (the drill floor) by the distance it was moved, and then dividing that value by the total weight of the elevated jack-up. In this case, the drill floor weighs 700 kips and was moved 10.0 feet to starboard. The total weight of the elevated jack-up is 14,000 kips. Plugging these values into the formula, we get: (700 kips x 10.0 feet) / 14,000 kips = 0.50 foot starboard. The other options are incorrect because they do not correctly apply the formula to calculate the change in TCG based on the provided information.
