Final answer:
A dial indicator is used to measure very small part movement with high accuracy, which is indeed true. These tools allow for minute measurements in increments as small as thousandths of an inch or ten-thousandths of a millimeter, contributing to their essential role in precision engineering. So, the correct option is A) True.
Step-by-step explanation:
The statement that a dial indicator is used to measure very small part movement is True.
Dial indicators are precision measuring tools used in engineering and mechanical work to measure small distances or objects' movements with high accuracy.
They can detect minute discrepancies in material, allowing for precision adjustments to machinery or components that require a fine degree of control.
These indicators can measure values in incredibly small increments, often down to thousandths of an inch or ten-thousandths of a millimeter, depending on the specific tool used.
This precision makes them an essential tool in ensuring that machinery and parts meet stringent specifications. Therefore, a dial indicator is indeed used to measure very small part movement with precision.
So, the correct option is A) True.
