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?
AI Explanation
The correct answer is D) 1462 lbs.
To calculate the stress exerted on each sling leg, we can use the formula: Stress on each sling leg = (Load weight) / (2 x Sine of (Angle between sling legs / 2)).
Given:
- Load weight = 1000 lbs
- Angle between sling legs = 140°
Plugging these values into the formula:
Stress on each sling leg = 1000 / (2 x Sine of (140° / 2))
Stress on each sling leg = 1000 / (2 x Sine of 70°)
Stress on each sling leg = 1000 / (2 x 0.9397)
Stress on each sling leg = 1462 lbs
The other options are incorrect because they do not correctly apply the formula for calculating the stress on each sling leg.
