Which statement accurately describes the Calculate CG method used in rigging?

• A. It uses only total length without weights
• B. It computes the center of gravity by weighting end distances relative to total length.
• C. It ignores end distances
• D. It uses height to compute CG

Answer: (B)

The essential idea is to locate the balance point along a rigging length by considering how the mass is distributed toward each end. The Calculate CG method does this by using end distances and weighting them relative to the total length. In practice, you measure how far the weight sits toward each end and express those distances as fractions of the overall length, then combine those fractions to determine where along the line the center of gravity lies. This captures how a load biased toward one end shifts the CG toward that end, which you wouldn’t get by using just the total length or by ignoring the end distances. Height isn’t involved in determining the CG along the length, since this method focuses on longitudinal distribution.
