What is the sling tension formula?

• A. Sling Tension = L x H x Share of Load
• B. (L/H) x Share of Load = Sling Tension
• C. Sling Tension = L x H x Total Weight
• D. Sling Tension = L/H + Share of Load

Answer: (B)

The key idea is that sling tension comes from two things working together: how the load is distributed among the slings (the share each sling carries) and the geometry of the sling setup (how long the sling is relative to the vertical height). The correct form says you take the portion of the load that this sling supports and multiply it by the ratio of the sling length to the vertical distance, L/H. This L/H factor represents how the sling angle affects tension: as the sling gets longer compared with the height, the angle increases and the tension grows, even though the actual load on that sling might be the same. So the sling tension is the load carried by that sling scaled by the geometry factor L/H. For example, if a sling is responsible for a certain portion of the load and the L/H ratio is 1.5, the tension in that sling is 1.5 times the load it carries. If another sling carries a different share but has a different L/H, its tension adjusts accordingly. This relationship captures both how the load is shared and how angle/geometry amplifies tension, which is why this form is the best choice compared with options that either omit the ratio, use total weight, or combine terms in a way that doesn’t reflect the geometric effect.
