Micrometer Screwguage

What is the function of a Micrometer?

• Measuring temperature accurately

• Counting large distances with low precision

• Measuring extremely small distances or objects with high precision.

• Weighing heavy objects

Name the parts of a Micrometer Screwguage.

• dial

• scale

• handle

• clamp

• frame, anvil, spindle, sleeve, thimble, ratchet stop

How can you read measurements accurately using a Micrometer?

• Follow the steps to ensure proper alignment and pressure, then read the main scale and thimble scale values to get an accurate measurement.

• Read the measurement in dim lighting conditions

• Guess the measurement without looking at the scale

• Use a ruler instead of a Micrometer

Explain the process of using a Micrometer to measure an object.

• Smash the object with the Micrometer

• Guess the measurement without using the Micrometer

• Use the Micrometer as a hammer to measure the object

• The process involves gently placing the object between the anvil and spindle, turning the thimble to touch the object, and reading the measurement value on the scales.

Why is a Micrometer more accurate than a Vernier Caliper?

• Micrometer is more expensive than a Vernier Caliper.

• Micrometer has a smaller scale division.

• Micrometer is less durable than a Vernier Caliper.

• Micrometer has a larger scale division than a Vernier Caliper.

What is the spindle in a Micrometer used for?

• Adjusting the focus

• Making precise measurements

• Holding the micrometer steady

• Measuring temperature

What is the thimble in a Micrometer used for?

• To measure small increments accurately

• To weigh small objects

• To measure large distances

• To cut fabric

How does the ratchet stop in a Micrometer help in accurate measurements?

• The ratchet stop is used to adjust the color of the micrometer, affecting the measurements.

• The ratchet stop is a decorative feature with no impact on the accuracy of measurements.

• The ratchet stop ensures consistent and controlled pressure is applied to prevent over-tightening and distortion of the object, resulting in accurate measurements.

• The ratchet stop increases the pressure randomly, leading to inaccurate measurements.

Explain the role of the frame in a Micrometer Screwguage.

• The frame adjusts the measurement scale

• The frame measures the depth of the object

• The frame determines the weight of the object

• The frame provides stability and alignment for accurate measurements.

What is the significance of the sleeve in a Micrometer?

• The sleeve is detachable for easy cleaning

• The sleeve is used to adjust the tension of the micrometer

• The sleeve is a decorative element with no functional purpose

• The sleeve provides the main scale reading for accurate measurements.
