Final answer:
A dial indicator is the correct tool to measure the runout of a crown gear. This tool allows accurate measurements of the deviation of a rotating gear from its ideal position.
Explanation:
In measuring the runout of a crown gear, the most suitable tool to utilize would be a dial indicator. Runout refers to the deviation of a physical feature from its ideal position during rotation. In the context of a crown gear, which is a type of gear used in transmissions for converting rotational motion, measuring runout is essential to ensure efficient functioning and reduce wear and tear.
While other options like the Vernier caliper, telescoping gauge, and micrometer are valuable mechanical measurement tools, they are not ideal for measuring runout. The dial indicator's design allows it to measure the runout by assessing the deviation as the gear rotates, providing a precise measurement. Thus, to check crown gear runout, a dial indicator is recommended for its accuracy and functionality. Other tools listed such as Vernier caliper, telescoping gauge, and micrometer are less suitable for this particular task.
