Answer :
Final answer:
A dial bore gage includes several components essential for measurements, including the Contact Head, Dial Indicator Housing, Main Body Assembly, and Spindle. The question asks which is not a part of the basic section of a dial bore gage, but without specific context for '9', it is hard to definitively identify it. However, the other components are critical and function together in this measurement tool.
Explanation:
Understanding Dial Bore Gage Components
A dial bore gage is a precision tool used to measure the internal diameters of cylindrical objects. It consists of several key components, each serving a specific purpose.
Components of a Dial Bore Gage
- Contact Head: This is the part that makes contact with the surface of the bore being measured.
- Dial Indicator Housing: This component houses the dial indicator, which provides a readout of the measurement.
- Main Body Assembly: This is the structural part that supports the other components of the gage.
- Spindle: The spindle serves to adjust the contact head within the bore during measurement.
In the options given (Contact Head, Dial Indicator Housing, Main Body Assembly, Spindle), all of these are essential components of a dial bore gage. However, if we consider the additional 9 given as an option in the original question which is not a standalone component of the dial bore gage, it is not clear, but the question intends to direct to the component that doesn't belong. Thus, while all options provided play a role in measurement, understanding that 9 does not clarify what it represents in this context is crucial for discerning the right answer.
