A cargo sling is rated for a given SWL when its legs hang vertically. As the angle between the sling legs increases, what happens to the tension in each leg?

  1. A. Tension in each leg decreases because the load is distributed over a wider area
  2. B. Tension in each leg remains constant provided the total load does not exceed the SWL
  3. Tension in each leg rises sharply, increasing the load on each leg and its fittingsCorrect
  4. D. Tension in each leg increases slightly but is offset by the reduced vertical component

Why C is correct

NAVEDTRA 14343 §8-4 states that as sling legs spread from the vertical, the tension in each leg rises sharply, so wide sling angles greatly increase the load on each leg and its fittings. The load is shared safely only at narrow angles.
