A sling is rigged on a piece of pipe weighing 1000 lbs. The angle between the sling legs is 140° and the legs are of equal length. What stress is exerted on each sling leg when the pipe is lifted?

Correct Answer: Option D — 1462 lbs.

Sling stress is calculated using the formula: Tension = Total Weight / (2 * cos(theta/2)). For a 1000 lb pipe with a 140° included angle, the tension on each leg equals 1462 lbs.
