Unformatted text preview: Appendix: Measuring tools To ease your entry into physics 241 labs, a description of some of the equipment that will be used is given here. Gadgetry covered here includes the vernier caliper and the micrometer Vernier Caliper A vernier caliper is a measuring device that can be used to find length and depth measurements, both inside and outside of an object. Calipers used in this laboratory are accurate to about one hundredth (.01) of a centimeter if used properly. The procedure for obtaining a reading from one is as follows: 1. Read the fixed scale to determine the number which will be at the left of the decimal place (usually, metric will be used here, so this will be millimeters). This number is the last whole number using the tick mark to the left of the zero line of the moveable scale (see figures). 2. Count the number of divisions from the zero line to the line which exactly lines up with a line on the fixed scale above it. This gives the next significant figure, to be added to thewith a line on the fixed scale above it....
