A measurement that includes both the maximum and minimum permissible sizes of a feature is known as what?

The correct choice refers to the concept of explicit tolerance. This term pertains to a specific measurement range where both the upper and lower limits of a feature are defined, ensuring that the dimensions remain within specified bounds during manufacturing. Explicit tolerances are clearly noted in the technical drawings or prints, allowing engineers and fabricators to understand exactly what is acceptable for each feature.

By defining both the maximum and minimum permissible sizes, explicit tolerance reduces ambiguity and helps maintain quality control in the production process. This precise understanding is essential in welding and fabrication, where fit and alignment may significantly impact the integrity of the assembly.

In contrast, general tolerance typically refers to a set of standard tolerances applicable across a range of dimensions, which may not specify the exact limits for each feature. Measured tolerance isn't a commonly accepted term in engineering documentation, and design tolerance refers more to the overall intent or allowances considered during the design phase, rather than specific measurements.
