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 system, tension on each leg increases as the included angle widens. Using the formula Strain = Total Weight / (2 * cos(theta/2)), for a 2000 lb load at a 90-degree angle, the strain calculates to approximately 1414 lbs per runner.
