Read each question carefully and provide your answers in the spaces provided. For measurement questions, assume the micrometer is calibrated correctly.
A micrometer is a precision measuring instrument used to obtain very accurate measurements of small distances. It is commonly used in mechanical engineering and machining.
1. A micrometer is used for making very measurements.
2. The main scale on a micrometer is called the .
3. One full rotation of the thimble moves the spindle by mm.
1. Which part of the micrometer is responsible for fine adjustments and securing the measurement?
Anvil
Spindle
Ratchet stop
Frame
2. What is the typical least count (smallest measurement) of a standard micrometer?
0.1 mm
0.01 mm
0.001 mm
1 mm
1. Briefly explain the purpose of the ratchet stop on a micrometer.
2. Describe the difference between a micrometer and a vernier caliper in terms of their precision and common applications.
1. The sleeve scale of a micrometer shows measurements in increments of 0.5 mm.
True
False
2. When reading a micrometer, the thimble scale reading is added to the sleeve scale reading.
True
False
