Question 479 Deck General

The correct answer is C) 1414 lbs. The amount of strain on each runner of a married fall system lifting 2000 lbs. when the angle made by the legs is 90° can be calculated using the formula for the tension in each leg of a married fall system: T = W / (2 * sin(θ/2)), where T is the tension in each leg, W is the total weight being lifted, and θ is the angle between the legs. In this case, with a weight of 2000 lbs. and an angle of 90°, the tension in each leg (or runner) is calculated as 1414 lbs. (2000 / (2 * sin(90°/2)) = 1414 lbs.). The other options are incorrect because option A) 1000 lbs. is too low, option B) 1154 lbs. is an approximate value but not the exact calculation, and option D) 2000 lbs. is the total weight being lifted, not the strain on each individual runner.
