What is the main function of a dial indicator?

To measure diameter
To measure small displacements
To calculate speed
To measure temperature

The correct answer is: To measure small displacements

The main function of a dial indicator is to measure small displacements with high precision. This instrument is commonly used in machining and assembly operations to determine the distance a surface has moved or to detect any variations in alignment. The dial indicator consists of a calibrated scale and a needle that moves in response to small changes in position. This makes it particularly useful for checking tolerances and ensuring parts fit together correctly. Measuring small displacements is crucial in many applications, such as leveling machinery or verifying the straightness of a shaft. The precision provided by a dial indicator allows millwrights and machinists to attain high-quality results in their work, ensuring that components function as intended. Its design specifically caters to tasks requiring fine measurement, solidifying its role as an essential tool in the millwright's toolkit.
