Final answer:
The preferred tool for measuring a cylinder's bore is the dial bore gauge. Other commonly used tools include inside micrometers, sliding verniers, and telescoping gauges. Dial bore gauges and inside micrometers offer more accurate and reliable measurements.
Step-by-step explanation:
The preferred tool for measuring a cylinder's bore is the dial bore gauge. A dial bore gauge is a measuring instrument used to accurately measure the diameter of a cylinder's bore. It consists of a gauge head with a dial indicator that displays the measurement, and anvils or extensions that contact the sides of the bore. The user can adjust the anvils or extensions to fit the bore, and then read the measurement on the dial indicator.
Another commonly used tool is the inside micrometer. It is designed to measure the internal dimensions of a cylindrical or tubular object, such as the bore of a cylinder. Inside micrometers typically consist of a micrometer head attached to a handle, and interchangeable measuring rods or contacts that can be adjusted to fit the bore.
While sliding verniers and telescoping gauges can also be used to measure a cylinder's bore, they may not provide as accurate and reliable measurements as dial bore gauges or inside micrometers.
