Draw a neat and labelled diagram of a screw gauge.
Name its main parts and state their functions.
The diameter of a thin wire can be measured by
(a) A vernier scale has 20 divisions. It slides over the main scale, whose pitch is 0.5 mm. If the number of divisions on the left hand of the zero of vernier on the main scale is 38 and the 18th vernier scale division coincides with the main scale, calculate the diameter of the sphere, held in the jaws of vernier callipers.
(b) If the vernier has a negative error of 0.04 cm, calculate the corrected radius of the sphere.
Up to how many decimal places can a common vernier callipers measure the length in cm?
State the correction if the negative error is 7 divisions when the least count is 0.01 cm.
Which part of vernier callipers is used to measure the internal diameter of a hollow cylinder?
