Recent statistical work is applied to measuring imbalance in a single plane, often referred to as static imbalance, for a rigid rotor. The two-dimensional repeatability and reproducibility of imbalance measurement are estimated by circles constructed from MANOVA-based method-of-moments and the results are compared to those of one-dimensional repeatability and reproducibility using the same measurement data. The results of both the one-dimensional and the two-dimensional repeatability and reproducibility are interpreted in terms of capability or how the measurement variation relates to rotor imbalance specification or tolerance.
