Question 4254 Deck General

The correct answer is C) variable loads. When the setback is lowered and placed in the pipe racks, it is considered a variable load. Variable loads are loads that can change in magnitude, direction, or position on the structure, such as cargo, equipment, and other movable items. In this case, the setback, which is a critical component of the drilling equipment, is being relocated and its position and weight on the structure can vary, making it a variable load. The other options are incorrect because basic loads refer to the permanent, unchanging loads on the structure, storm loads are the loads specifically caused by severe weather conditions, and fixed loads are loads that are permanently attached to the structure and do not change in magnitude or position.
