A screw gauge has divisions on its circular scale. The circular scale is units ahead of the pitch scale marking, prior to use. Upon one complete rotation of the circular scale, a displacement of is noticed on the pitch scale. The nature of zero error involved and the least count of the screw gauge, are respectively:
A screw gauge with a pitch of and a circular scale with divisions is used to measure the thickness of a thin sheet of aluminium. Before starting the measurement, it is found that when the two jaws of the screw gauge are brought in contact, the division coincides with the main scale line and that the zero of the main scale is barely visible. What is the thickness of the sheet if the main scale reading is and the division coincides with the main scale line?
The least count of the main scale of a vernier calipers is . Its vernier scale is divided into divisions and coincide with divisions of the main scale. When jaws are touching each other, the division of the vernier scale coincides with a division of the main scale and the zero of vernier scale is lying right side of the zero of the main scale. When this vernier is used to measure the length of the cylinder the zero of the vernier scale between and and VSD coincides with the main scale division. The length of the cylinder is (VSD is vernier scale division)
The nearest star to our solar system is light years away. The distance of this star in Parsec is (Mean distance between the earth and the sun and one light year
The pitch and the number of divisions, on the circular scale, for a given screw gauge are and respectively. When the screw gauge is fully tightened without any object, the zero of its circular scale lies divisions below the mean line.
The readings of the main scale and the circular scale, for a thin sheet, are and respectively, the thickness of this sheet is:
A specially designed Vernier caliper has the main scale least count of . On the Vernier scale, there are 10 equal divisions and they match with 11 main scale divisions. Then, the least count of the Vernier caliper is:
If the screw on a screw-gauge is given six rotations, it moves by on the main scale. If there are divisions on the circular scale the least count of the screw gauge is:
In a screw gauge, complete rotations of the screw cause it to move a linear distance of . There are circular scale divisions. The thickness of a wire measured by this screw gauge gives a reading of main scale divisions and circular scale divisions. Assuming negligible error, the thickness of the wire is
Diameter of a steel ball is measured using a Vernier calipers which has divisions of 0.1 cm on its main scale (MS) and 10 divisions of its Vernier scale (VS) match 9 divisions on the main scale. Three such measurements for a ball are given as:

If the zero error is - 0.03 cm, then mean corrected diameter is:
The diameter of a cylinder is measured using a vernier callipers with no zero error. It is found that the zero of the vernier scale lies between and of the main scale. The vernier scale has divisions equivalent to . The division of the vernier scale exactly coincides with one of the main scale divisions. The diameter of the cylinder is,
The pitch of the screw gauge is and there are divisions on the circular scale. When nothing is put in between the jaws, the zero of the circular scale lies divisions below the reference line. When a wire is placed between the jaws, the first linear scale division is clearly visible while division on circular scale coincides with the reference line. The radius of the wire is
There are two vernier calipers both of which have divided into equal divisions on the main scale. The Vernier scale of one of the calipers has equal divisions that correspond to main scale divisions. The Vernier scale of the other caliper has equal divisions that correspond to main scale divisions. The readings of the two calipers are shown in the figure. The measured values (in ) by calipers and respectively, are
A student measured the diameter of a small steel ball using a screw gauge of least count . The main scale reading is and division of circular scale coincides with reference line. If screw gauge has a zero error of , the correct diameter of the ball is
Consider a Vernier calipers in which each on the main scale is divided into equal divisions and a screw gauge with divisions on its circular scale. In the Vernier calipers, divisions of the Vernier scale coincide with divisions on the main scale and in the screw gauge, one complete rotation of the circular scale moves it by two divisions on the linear scale. Then:
