Question 1 of 27070

If the thimble of a micrometer were turned through one complete revolution, the micrometer would open or close by a linear distance of __________.

🔍 Key Concepts

• Micrometer screw pitch – how far the spindle moves with one full turn • Relationship between threads per inch (TPI) and linear travel • How the thimble markings relate to 0.001 inch graduations

💭 Think About

• Think about the standard thread pitch used in a common machinist’s micrometer: how many threads per inch does its screw usually have? • If the screw has that many threads per inch, how far does the spindle move for ONE full revolution of the thimble? • Compare that linear movement to the size of each individual graduation you normally read on the micrometer thimble.

✅ Before You Answer

• Recall or look up the typical threads per inch of a standard micrometer screw (not a special fine or coarse type). • Calculate: distance per turn = 1 ÷ (threads per inch) and then match that number to one of the choices. • Verify that your choice matches the distance between 0.001 inch graduations around the thimble when it makes one full revolution.
