Answer :
Final answer:
The correct tool for measuring input shaft and output shaft endplay is a Dial Indicator, which is specialized for accurately measuring small movements and is essential for precision in engineering applications. therefore option (2) is correct
Explanation:
The correct tool for measuring input shaft and output shaft endplay is a Dial Indicator. Unlike micrometers or dial calipers, which are more suited for measuring the thickness or external dimensions of objects, a dial indicator is specialized for measuring minute amounts of movement and is thus perfectly suited for precision measurements like shaft endplay in mechanical engineering applications. It is important to use the right tool for accurate measurements in engineering, as precision can significantly influence the performance and safety of mechanical systems.
