In the sling stress formula, the Load Factor is multiplied by the load's weight and divided by the number of legs. Which expression represents this relationship?

In the sling stress formula, the Load Factor is multiplied by the load's weight and divided by the number of legs. Which expression represents this relationship?

• A. Sling Length ÷ Vertical Height = Load Factor × Weight ÷ Number of Legs
• B. Weight ÷ Number of Legs = Sling Length ÷ Vertical Height × Load Factor
• C. Load Factor = Number of Legs ÷ (Sling Length × Weight)
• D. Number of Legs = Sling Length × Vertical Height ÷ (Load Factor × Weight)

Answer: (A)

The relation being tested shows how the sling’s geometry connects to the load that each leg must carry after applying the Load Factor. In this approach, the ratio of the sling length to the vertical height reflects the per-leg load produced by the combination of the load’s weight and the Load Factor, with that total divided among the number of legs. So the per-leg load is (Load Factor × Weight) ÷ Number of Legs. Equating this to Sling Length ÷ Vertical Height captures the idea that as the sling geometry changes (length relative to height), it corresponds to how much load each leg must take after factoring in dynamics and distribution. That’s why the expression Sling Length ÷ Vertical Height = Load Factor × Weight ÷ Number of Legs is the correct representation. For example, if Weight is 8, Load Factor is 1.5, and there are 2 legs, the per-leg load is (1.5 × 8) ÷ 2 = 6. The geometry ratio L/H would then be 6, illustrating how the two sides of the equation mirror each other.
