Read each question carefully and answer to the best of your ability. Refer to the provided image of a micrometer for relevant questions.
Figure 1: A typical outside micrometer.
1. What is the primary purpose of a micrometer?
To measure large distances accurately
To measure small lengths with high precision
To weigh objects with great accuracy
To determine the volume of irregular shapes
2. Which part of the micrometer (refer to Figure 1) is responsible for fine adjustments and preventing overtightening?
Anvil
Spindle
Thimble
Ratchet stop
3. The least count of a standard micrometer is typically micrometers or millimeters.
4. When taking a measurement, the main scale reading is taken from the , while the thimble scale reading provides the value.
5. The frame of a micrometer is usually C-shaped to provide rigidity and prevent deflection during measurement.
True
False
6. A micrometer can be used to measure both internal and external dimensions with the same accuracy.
True
False
7. Explain the concept of 'zero error' in a micrometer and how it can be corrected.
