Answer :
Final answer:
meaning the dial is graduated in thousandths of an inch and has a total hand movement capacity of two hundred thousandths of an inch.The correct option is c. 0.001 inches (0.0025 cm), 0.200 inches (0.508 cm)
Explanation:
The universal type dial test indicator is typically a precision measurement tool used in engineering and machining to measure small distances or angles. The graduations on the dial allow for accurate readings to be taken, with some common increments being in thousandths or ten-thousandths of an inch. When considering the options provided, the correct answer is c. 0.001 inches (0.0025 cm), 0.200 inches (0.508 cm).
This means that each graduation on the dial is equivalent to one-thousandth of an inch, and the total hand movement that the dial test indicator can measure is up to two hundred thousandths of an inch.Understanding the precision of measurement tools like dial test indicators is essential in ensuring accurate and reliable measurements in any engineering project.
It is analogous to using rulers with different markings, such as centimeters or millimeters, where certain digits are known and others are estimated based on the smallest division that can be confidently read. For example, a ruler with millimeter markings will provide a more precise measurement than one with only centimeter marks.
