Which term refers to a geometric representation of the forces acting on a load during lifting?

• A. Bend Ratio
• B. Sling Angle
• C. Load Triangle
• D. Selvedge

Answer: (C)

The forces on a lifted load are shown in a geometric diagram that makes how the weight is supported by the sling tensions easy to see. This is the Load Triangle. In a two-leg sling, the two tension vectors along the sling legs and the downward weight form a closed shape, with the vertical components of the tensions supporting the weight. If the sling legs are symmetric, the horizontal components cancel, and you can read off how changing the sling angle affects the required tension in each leg. A handy way to think about it is 2T cos θ = W, so each leg carries T = W/(2 cos θ) for a given angle θ from vertical. This triangle is why the term fits: it represents the actual balance of forces on the load in a single, clear diagram.
