185. 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?

The tension in each sling leg is calculated using the formula T = W / (2 * cos (θ)), where W is the load (1000 lbs) and θ is half the included angle (70). Substituting these values yields a tension of approximately 1462 lbs per leg, as the angle decreases, the tension increases.
