If in a Vernier callipers 10 VSD coincides with 8 MSD, then the least count of Vernier calliper is [given 1 MSD = 1 mm]
The diameter of a cylinder is measured using vernier calipers with no zero error. It is found that the zero of the vernier scale lies between 5.10 cm and 5.15 cm of the main scale. The vernier scale has 50 divisions equivalent to 2.45 cm. The 2 4 t h division of the vernier scale exactly coincides with one of the main scale divisions. The diameter of the cylinder is : There are two Vernier calipers both of which have 1 cm divided into 1 0 equal divisions on the main scale. The Vernier scale of one of the calipers ( C 1 ) has 1 0 equal divisions that correspond to 9 main scale divisions. The Vernier scale of the other caliper ( C 2 ) has 1 0 equal divisions that correspond to 1 1 main divisions. The readings of the two calipers are shown in the figure. The measures values (in cm) by calipers C 1 and C 2 respectively, are.
In a vernier calliper 19 main scale divisions concide with 20 vernier scale divisions .if the main scale has 20 divisions in a centimetre, calculate L.C. ofvernier calliper ans 0.0025 cm
Method 1: Number of divisions in which 1 cm is divided on the main scale = 20 Value of the smallest division on the main scale = 1/20 cm= 0.05 cm Number of divisions on vernier scale =20 Least Count of the vernier callipers= (value of smallest division on the main scale)/(number of divisions on the vernier scale) = 0.05 cm/20= 0.0025 cm The least count of the vernier callipers= 0.0025 cm. Method 2: Smallest division on the main scale = 0.05 cm 20 vernier divisions = 19 main scale divisions 1 vernier division = 19/20 main scale divisions Difference between 1main scale division and 1 vernier division= 1 msd - 19/20 msd =1/20 msd= 1/20×0.05cm= 0.0025 cm. The least count of the vernier callipers = 0.0025cm
A vernier has 10 divisions and they are equal to 9 divisions of the main scale in length. If the main scale is calibrated in mm, what is its least count?
Q. The main scale of a vernier callipers is calibrated in mm and 19 divisions of main scale are equal in length to 20 divisions of vernier scale. In measuring the diameter of a cylinder by this instrument, the main scale reads 35 divisions and 4th division of vernier scale coincides with a main scale division. The least count is 5 × 10 − x c m. Find the value of x. Q. A vernier callipers has its main scale graduated in mm and 10 divisions on its vernier scale are equal in length to 9 mm. When the two jaws are in contact. the zero of vernier scale is ahead of zero of main scale and 3rd division of vernier scale coincides with a main scale division. The least count is 10 − x c m. Find the value of x.
