Manual vernier caliper least count

Aim: To measure (a) diameter of a small spherical/cylindrical body and (b) to measure internal diameter and depth of a given beaker/calorimeter using Vernier Callipers and (c) hence find its volume Apparatus: • Vernier Calliper • Cylinder (Metal) • Beaker Graduated Theory: A Vernier Calliper has two scales–one main scale and a Vernier scale. Vernier Scale slides along the main scale. The main scale and Vernier scale are divided into small divisions though of different magnitudes. Generally, each division of Vernier scale is smaller than each division of main scale. In our example nine main scale division is equals to ten vernier divisions. The main scale is graduated in cm and mm. It has two fixed jaws, A and C, projected at right angles to the scale. The sliding Vernier scale has jaws (B, D) projecting at right angles to it and also the main scale and a metallic strip (N). The zero of main scale and Vernier scale coincide when the jaws are made to touch each other. The jaws (A, B) are used to measure external diameter of an object, Jaws (C, D) are used to measure internal diameter of an object and metallic strip are designed to measure the height / depth of any object. Knob P is used to slide the Vernier scale on the main scale. Screw S is used to fix the Vernier scale at a desired position. The least count of a common scale is 0.1 cm or 1 mm. It is difficult to further subdivide it to improve the least count of the scale. A Vernier scale enables this to be a...

The least count of the metre scale is 1mm, and that of the ammeter is 2 ampere. Measurement of Length with a Metre Scale In daily life, the length is measured with the help of a metre scale. It is graduated in cm and mm, such that the value of one small division is 1 mm. Thus, a metre scale can be used to measure a length accurately up to 1 mm. Vernier Callipers Vernier callipers, instruments for making very accurate linear measurements, were introduced in 1631 by Pierre Vernier, a French mathematician. Vernier Calliper – Parts 1. Main Scale – The main scale is simil...
