Micrometer Screw Gauge Measurements

The video tutorial explains how to measure the thickness of a coin using a micrometer screw gauge. It covers the components of the micrometer, including the main and vernier scales, and demonstrates how to read these scales to obtain a precise measurement. The tutorial walks through the calculation process, showing how to combine the readings from the main and vernier scales to get the final measurement. The example concludes with a calculated thickness of 1.60 mm, matching the correct answer option.
