In the sling calculation example, what is the load factor (RF) used for a round load?

• A. 1.0
• B. 0.75
• C. 0.5
• D. 1.25

Answer: (B)

The main idea here is that RF is a correction factor used in sling calculations to reflect how the load is carried by the sling when the load shape affects how forces distribute. For a round load, the sling wraps around the cylinder, and the contact and friction change how much of the total weight actually shifts into the sling’s lines. In the round-load scenario, the example uses a load factor of 0.75, meaning you take 75% of the total weight as the load to use in the calculations. This accounts for the way the load sits and how the sling legs share the force, giving a more realistic and conservative result. The other values wouldn’t match the round-load conditions described in the example.
