🔍 Key Concepts

• How to read a standard inch micrometer with 0.025 inch increments on the sleeve and 0.001 inch increments on the thimble • Finding the last fully visible 0.025" mark on the sleeve to get the base reading • Adding the thimble reading (in thousandths of an inch) to the sleeve reading to get the total measurement

💭 Think About

• First, decide which 0.025" line on the sleeve is the last one you can clearly see to the left of the thimble edge. What base value does that give you? • Next, find which thimble line lines up exactly with the horizontal reference line on the sleeve. How many thousandths of an inch does that add? • When you add the sleeve value and the thimble value, which of the choices is closest to your total?

✅ Before You Answer

• Be certain you are not including any sleeve line that is partially covered by the thimble – only count fully visible 0.025" marks • Verify that you are reading the thimble scale in 0.001" increments, not 0.0001" or another value • Double-check your addition of sleeve + thimble reading before comparing against the multiple-choice answers
