What is the term for the ratio of the diameter of the sling to the diameter of the object it is bending around?

• A. Bend Ratio
• B. Selvedge
• C. Loop Eye
• D. Sling Angle

Answer: (A)

When a sling wraps around a round object, how tight that bend is depends on the relative sizes of the sling and the object. The term that describes this relationship is bend ratio, defined as the sling diameter divided by the object's diameter. This ratio helps determine whether the bend is safe or too sharp, which can cause excessive wear, deformation, or damage to the sling or the object.

The other terms don’t describe this specific relationship: selvedge is a woven fabric edge, a loop eye is a sling component at the end, and sling angle refers to the angle between two legs of a lift rather than a diameter-to-diameter ratio.
