What are the minimum and maximum measurements of a shaft given 2.125 plus or minus .015?

To determine the minimum and maximum measurements of a shaft given a nominal size of 2.125 inches with a tolerance of plus or minus 0.015 inches, you start by calculating the range of acceptable measurements.

The nominal size is 2.125 inches. When applying the tolerance of plus or minus 0.015 inches:

1. For the maximum measurement, you add the tolerance:

• 2.125 + 0.015 = 2.140 inches

2. For the minimum measurement, you subtract the tolerance:

• 2.125 - 0.015 = 2.110 inches

This results in a range of 2.110 inches to 2.140 inches for the shaft dimensions.

Therefore, the correct answer accurately reflects this calculation, showing that the shaft's dimensions fall between 2.110 and 2.140 inches. This emphasizes the importance of understanding tolerances in engineering and mechanical work, which ensures proper fit and function in assemblies.
