If a 40-pound generator applies +1400 inch-pounds to a reference axis, the generator is located how far from the axis?

Explanation:
In weight and balance, moment equals weight times the arm (distance from the reference axis), and the sign of the moment shows which side of the axis the load is on. Here the generator has a positive moment of +1400 inch-pounds and weighs 40 pounds. To find the arm: 1400 ÷ 40 = 35 inches. The positive moment means the arm is on the positive side, so the distance is +35 inches. Therefore, the generator is located 35 inches from the axis in the positive direction. The other options either use the wrong direction or the wrong calculation (they mix up sign or treat moment and distance as the same quantity).
