The amount of strain on each runner of a married fall system lifting 2000 lbs. when the angle made by the legs is 90° would be __________.

Correct Answer: Option C — 1414 lbs.

In a married fall (union purchase) rig with a 90-degree included angle between the runners, the tension on each leg equals the load multiplied by the cosecant of half the angle, resulting in 2,000 times 0.707, yielding 1414 lbs of strain.
