[0 EXPERIMENT-§ © AIM: To measure diameter of a small spherical/cylindrical body using Vernier Calipers. APPARATUS Vernier Callipers, a spherical body (pendulum bob) or a cylinder and a magnifying lens. THEORY If with the body between the jaws, the zero of vernier scale lies ahead of Nth division of main scale, then main scale reading (M.S.R.) = N, If nth division of vernier scale coincides with any division of main scale, then vernier scale reading (V.S.R.) =nx(L.c) (L.C. is least count of vernier callipers) =nx(V.C.) (V.C. is vernier constant of vernier calipers) Total reading, T.R. = M.S.R.+V.S.R. (L.C. = V.C.) =N+nx (VC), DIAGRAM 7 Main Scale 5 6 7 8 8 10 E MTAETTATHOTSCTNUFTOUTECU CTEM TEUTTUT {out ut to wtalautanl [— Pp Fig. Vernier Callipers—Measuring diameter of a sphere. ROCEDURE 1.
