If a payload of 150 lb is moved from arm 70 in to 90 in, the change in total moment is what?

Explanation:
Moment in weight and balance is found by multiplying the weight by its arm. Moving a payload outward increases the moment; moving it inward decreases it. Here, the payload is 150 lb and its arm moves from 70 in to 90 in, a shift of 20 in outward. The change in total moment is 150 × 20 = 3,000 in-lb, a positive change. This means the total moment increases by 3,000 in-lb.
