Vernier Calipers and Screw Gauge

physics Experiment -
Use of Vernier Calipers to (i) measure diameter of a small spherical/cylindrical body, (ii) measure the dimensions of a given regular body of known mass and hence to determine its density; and (iii) measure the internal diameter and depth of a given cylindrical object like beaker/glass/calorimeter and hence to calculate its volume.
Use of screw gauge to (a) measure diameter of a given wire, (b) measure thickness of a given sheet; and (c) determine volume of an irregular lamina.
