Dial indicators are used to:

A. Indicate the movement of dials
B. Check the smoothness of a machined part
C. Indicate errors
D. Indicate the alignment of an object

Answer :

Final answer:

Dial indicators are primarily used for indicating errors and aligning objects in engineering. They precisely measure small distances to ensure that components meet specified tolerances. Although they can help in understanding part alignment, they don't specifically measure smoothness.


Explanation:

Understanding Dial Indicators


Dial indicators are precision measuring instruments that are primarily used in the field of engineering. Their main purpose is to provide measurements of small distances or angles, which can help in various applications like checking the alignment of components or determining the depth of holes.


From the options provided, the most accurate use of dial indicators can be seen in:



  2. Indicate errors - Dial indicators can be used to check for tolerances and to find deviations from a specified measurement, helping to identify errors in parts.

  4. Indicate the alignment of an object - They are commonly employed to ensure that mechanical parts are aligned correctly, which is crucial for functioning machinery.


While some might think they check the smoothness of machined parts, this is not the primary function of a dial indicator. Instead, smoothness is usually assessed through surface finish gauges or similar tools.
