A geometric representation of the forces acting on a load during lifting is known as what?

• A. Selvedge
• B. Loop Eye
• C. Type III Web Sling
• D. Load Triangle

Answer: (D)

Think of it as a force diagram drawn as a triangle. When you lift a load, the weight pulling downward and the two lifting legs pull in from the load to form a balance of forces. The Load Triangle (force triangle) represents these forces graphically: the weight vector points down, the tensions in the two lifting legs point along the slings toward their anchors, and the triangle closes with the third side showing how those tensions relate to the weight. This visualization helps you see how much tension each leg must carry and how changing the sling angles changes those tensions, which is essential for safe, effective rigging. The other terms refer to parts or types of slings, not a diagram of forces.
