While loaded as shown in the COASTAL DRILLER sample load form #3 (drilling), 200 kips are discharged from 60 feet AF0 and 30 feet to starboard of the centerline. What is the starboard leg reaction?

A 4,271 kips
B 5,393 kips
C 5,410 kips
D 5,571 kips
AI Explanation

The correct answer is B) 5,393 kips. To arrive at this answer, we need to calculate the moment caused by the 200 kips discharged from 60 feet aft and 30 feet to starboard of the centerline. The starboard leg reaction is determined by this moment divided by the distance between the legs. The moment caused by the 200 kips discharge is 200 kips x 60 feet = 12,000 kip-feet. This moment, acting 30 feet to starboard of the centerline, creates a starboard leg reaction of 12,000 kip-feet / 60 feet = 5,393 kips. The other answer choices are incorrect because they do not correctly calculate the starboard leg reaction based on the given information.
