Question 590 Deck General
70% to passA 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?
A
1318 lbs.
B
1366 lbs.
C
1414 lbs.
D
1462 lbs.
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.
