Answer :
Final answer:
The tool used to perform final alignment measurements is b. Dial indicators. These are precise measuring tools ideal for fine adjustments in alignments, as they provide a continuous reading of movement. Therefore, the correct answer is b. Dial indicators.
Explanation:
The student's question is about identifying which tool is used to perform final alignment measurements. The correct answer from the given options is b. Dial indicators. Dial indicators are precision measuring tools used to measure small distances or angles and are often used in the final stages of alignment to ensure precision.
They are superior to options such as micrometers for this task because they provide a continuous reading of movement, which is ideal for the fine adjustments required in final alignments.
Other tools mentioned, such as micrometers, feeler gauges, and taper gauges, serve different purposes. Micrometers are used for highly precise measurements of diameter or thickness, feeler gauges are used to measure gap widths, and taper gauges measure the openness of small spaces. However, for the specific task of final alignment measurements, dial indicators are the most appropriate tool.
