Can 100 pounds of weight be shifted from Station 30.0 to Station 120.0 without exceeding the aft CG limit?

• A. No, it exceeds the aft CG limit
• B. Yes, resulting in a new CG at Station 117.69
• C. Yes, but the CG will remain the same
• D. No, it does not affect CG location

Answer: (B)

To determine whether the shift of 100 pounds from Station 30.0 to Station 120.0 affects the center of gravity (CG) and whether the aft CG limit is exceeded, one must calculate the new CG location after the weight shift.

Initially, the moment created by the weight at Station 30.0 can be calculated as the weight multiplied by its distance from a reference point. When the weight is moved to Station 120.0, the moment will similarly be calculated using this new location. The total moment is then divided by the total weight to find the new CG location.

The calculation shows that after moving 100 pounds from Station 30.0 to Station 120.0, the new CG is calculated to be at Station 117.69. This indicates the forward movement of the CG while remaining within the allowable aft limit.

Thus, confirming that the weight shift not only results in a new CG position but also ensures that it has not exceeded the aft CG limit. Therefore, the correct conclusion is that the shift can occur without breaching the aft CG limit, and it results in a new CG at Station 117.69.
