Which factor is NOT listed as a determinant of sling tension?

• A. Sling length
• B. Distance between attachment points
• C. Color of the sling
• D. Spatial relationship to the center of gravity

Answer: (C)

Sling tension is governed by how the sling is arranged around the load and where the weight acts, not by cosmetic attributes like color. The length of the sling sets the range of angles the sling can form with the load; changing the length changes those angles and therefore how much tension each leg must carry. The distance between attachment points changes how the sling legs spread around the load, which also alters the pull angles and the resulting tension. The spatial relationship to the center of gravity tells you how the load’s weight is shared between the sling legs; if the CG is off-center, one leg can take more load, increasing its tension. The color of the sling has no effect on these geometric and load-distribution factors, so it does not determine sling tension.
