Aim To measure diameter of a given wire and thickness of a given sheet using screw gauge. Apparatus and Material Required Principle A screw gauge works on the principle of a screw. When a screw is rotated in a nut, the linear distance moved by it is directly proportional to the number of rotations given to…
Aim (i) To measure the diameter of a given spherical body (e.g. a glass marble) using Vernier Callipers (ii) To measure the internal diameter and depth of a given beaker using Vernier Callipers, and hence to determine its volume. Apparatus and Material Required Principle A Vernier Callipers measures lengths more precisely than an ordinary scale. It…
