Final answer:
A bore gage is the instrument capable of measuring both the internal diameter and the depth of a hole. Examples of using measurement tools include using calipers for a grub and a measuring wheel or tape measure for the width of a street.
Step-by-step explanation:
An instrument that can measure both the internal diameter (ID) and the depth of a hole is a bore gage. Specifically designed to gauge the inside diameter of a hole, a bore gauge can come with depth rods or extensions that allow measurement of the depth as well. Calipers, while versatile in measuring external and internal dimensions, don't as accurately measure depth as bore gauges. Split-ball gages are used to measure the internal diameters but not the depth, and pin gauges are used for checking sizes and tolerances of holes, with no depth measurement capability.
To match a tool with the unit you are using to measure an object, consider the level of precision needed and the type of measurement. For example, when measuring something that contains millimeters, a ruler may be used if high precision isn't critical. However, for more precise measurements, tools like calipers and micrometers would be more appropriate.
Review:
- For a grub collected from the garden, a caliper would be appropriate to provide a precise measurement.
- The width of a street would be best measured with a measuring wheel or tape measure, given its large span.
