Traction Calcul RR

The document presents a Measurement Systems Analysis focusing on Repeatability and Reproducibility (R&R) for a traction machine with specified characteristics and test results from three appraisers. It includes detailed data on average measurements, ranges, and calculations for equipment variation, appraiser variation, and total variation percentages. The results indicate a total variation of 15.194176 with specific contributions from repeatability and reproducibility factors.
