In a screw gauge, keeping pitch of the screw constant, if we increase the number of head scale divisions, then its accuracy of measurement

Without changing the number of divisions on the circular scale, if the pitch of the screw gauge is halved, then its accuracy of measurement

Accuracy of screw gauge can be increased by …………. The number of divisions on circular scale.

Pitch of the screw gauge is 0.5mm . Its head scale contains 50 divisions. The least count of it is

A vernier calipers and a screw gauge have the same least count and zero error with the difference that the vernier calipers has positive zero error and the screw gauge has negative zero error. The number of circular scale divisions on the screw gauge is twice the number of vernier scale divisions on the vernier calipers and the pitch of the screw gauge is 1mm. If the vernier coinciding division and the circular are 3 and 97, respectively then find the number of vernier scale divisions on the vernier calipers.

Answer the following : (a) You are given a tread and a metre scale. How will you estimate the diameter of the thread ? (b) A screw gauge has a pitch of 1.0 mm and 200 divisions on the circular scale. Do you think it is possible to increase the accuracy of the screw gauge arbitratily by increasing the number of divisions on the circular scale ? (c) The mean diameter of a thin brass rod is to be measured by vernier callipers. Why is a set of 100 measurements of the diameter expected to yield a more reliable estimate than a set of 5 measurement only ?

The pitch of a screw gauge is 0.5 mm. It's head scale contains 50 divisions. The least count of the screw gauge is

The pitch of a screw gauge is 0.5 mm. It's head scale contains 50 divisions. The least count of the screw gauge is

is it possible to increase the accuracy of screw gauge by increasing the number of divisions on the head scale?

How can we increase the relative accuracy of measurement by a screw gauge ?

In a screw gauge, the main scale has divisions in millimetre and circular scale has 50 divisions. The least count of screw gauge is
