A weight of 600 lb located at 50 inches has a moment of 30,000 in-lb. Which option shows this correct moment?

Explanation:
Moment is the turning effect produced by a weight, calculated as weight times its distance from the reference point. With a weight of 600 lb located 50 inches from the datum, the moment is 600 × 50 = 30,000 in-lb. This matches the given moment exactly. If the moment were different, you’d need a different arm length—for 28,000 in-lb the arm would be about 46.7 inches, for 26,000 in-lb about 43.3 inches, or for 32,000 in-lb about 53.3 inches. Since the arm is 50 inches, the moment is 30,000 in-lb.
