Answer :
Final answer:
The smallest incremental readings on a dial caliper are obtained using the dial indicator, which offers precise measurement capabilities. While other parts like the bar or inside contacts serve important functions, they do not provide the same level of detail as the dial indicator. Thus, for accurate measurements, the dial indicator is preferred.
Explanation:
Understanding Dial Calipers
A dial caliper is a precision instrument used for measuring dimensions such as length, width, and height with high accuracy. It features a dial gauge for reading measurements, making it a valuable tool in various fields, including engineering and machining.
Smallest Incremental Readings
The smallest incremental readings on a dial caliper are obtained on the dial indicator. The dial indicator provides a clear and precise reading of measurements, often down to fractions of a millimeter or inch. To explain:
- The dial indicator shows the measurement via a rotating needle on a dial face, allowing users to see small increments clearly.
- Other components like the bar, depth rod, and inside contacts help measure specific dimensions but do not typically offer the level of detail in readings that the dial indicator does.
- For example, while the inside contacts can measure the internal dimensions of an object, they do not provide the same incremental detail as the dial indicator.
In conclusion, for obtaining the smallest incremental readings on a dial caliper, the focus should be on utilizing the dial indicator for its precision.
