If the center of gravity is exactly midway between lift points A and B, what is the weight carried by each lift point for a 9,000-pound load?

4,500 lb 6,000 lb 9,000 lb 3,000 lb

Correct Answer:

4,500 lb

Explanation:

When the center of gravity lies exactly midway between two lift points, the load is shared equally by both supports. The total weight is 9,000 lb, so each lift point carries half of that. Therefore, each supports 4,500 lb. If the center of gravity shifted toward one lift, the nearer lift would carry more and the farther lift less, but at the midpoint the forces are equal.
