Try to measure the quantities of the following objects. Quantities to Measure Micrometer Vernier Caliper 1) Diameter of a 1-peso coin 2) Thickness of a 5-peso coin 3) Thickness of your hair ![]() Okay, that is enough! Let us try to apply it in real life. In figure 6 the zero and the ten on the vernier scale both line up with main scale readings, therefore the reading is 4.000 cm. 0.60 mm or 0.060 cm) on the vernier scale. The remaining digit is taken from the vernier scale reading that lines up with any main scale reading, (i.e. In figure above, the first significant figures are taken as the main scale reading to the left of the vernier zero, i.e. 0.46 mm or 0.046 cm) on the vernier scale. The remaining digits are taken from the vernier scale reading that lines up with any main scale reading, (i.e. In figure 4 above, the first significant figures are taken as the main scale reading to the left of the vernier zero, i.e. The Vernier Caliper This instrument may be used to measure outer dimensions of objects (using the main jaws), inside dimensions (using the smaller jaws at the top), and depths (using the stem). Thus you might assign a Reading Error to this measurement of 0.003 mm So, we would report the distance as 8.624 ± 0.003 mm. 8.5 mm 0.120 mm 8.500 mm + 0.12 4 mm = 8.62 4 mmĭepending on your eyes and screen resolution, you might be fairly confident that the reading is less than, say, 8.627 mm and similarly confident that it is greater than 8.621 mm. We might estimate this reading to be 8.624 mm. Now the distance is greater than 8.620 mm, but clearly less than 8.630 mm. 8.5 mm 0.120 mm 8.500 mm + 0.120 mm = 8.620 mmįinally, if we turn the thimble a tiny bit further, it might end up like the figure above. Now the distance is 0.120 mm greater than 8.500 mm, so the distance is 8.620 mm. If we give the thimble one complete further rotation, we end up with the micrometer as shown above. We have increased the distance by 0.120 mm from 8.000, so the distance between the measuring rods is now 8.120 mm. Now turn the thimble just a little bit more, and end up with the situation shown. One more complete revolution takes the distance to 8.000 mm, as shown. Thus the numbers on the thimble correspond to hundredths of a millimeter. 3) Note that this is all consistent with the fact that the markings on the cylinder correspond to fifty divisions for a complete revolution. The downward line on the cylinder corresponding to 7.5 mm is barely visible. 2) Now the distance between the measuring rods is 7.500 mm. ġ) If we rotate the thimble one complete revolution so it moves to the right, it will look as shown. ( That is why it is called a micrometer, 10 -6 of a meter). Your instrument is capable of reading up to thousandths of a millimeter. The upward line on the cylinder corresponding to 7 mm is barely visible under the thimble. 3) In this case, then, the distance between the measuring rods is 7.000 mm. The left-hand side of the thimble has markings all around it. When it lines up with the central horizontal line on the cylinder, as shown, then the distance between the measuring rods is exactly an integral or half-integral number of millimeters. The line labeled 0 is the primary pointer. It is one of the most accurate mechanical devices in common use. The Micrometer A micrometer allows a measurement of the size of a body. What are we going to do today? 1) We are going to read and use the following instruments in measuring certain quantities: Micrometer Vernier Caliper Casinillo Faculty Measurement and Measuring Devices (Micrometer and Vernier Caliper)
