The main scale is 'life size,' while the sliding scale is. For example, if the main scale's smallest lines represent 0.1 inches, then each numbered division on the Vernier scale represents 0.01 inches. (C) If the least count of the linear scale of the screw gauge is twice the least count of the Vernier callipers, the least count of the screw gauge is 0.01 mm. If the sliding scale doesn't have a label, you can assume the numbered divisions represent 1/10 of the smallest division on the main scale. (B) If the pitch of the screw gauge is twice the least count of the Vernier callipers, the least count of the screw gauge is 0.005 mm. (A) If the pitch of the screw gauge is twice the least count of the Vernier callipers, the least count of the screw gauge is 0.01 mm. In the Vernier callipers, 5 divisions of the Vernier scale coincide with 4 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. = main scale reading + screw gauge reading вЂ“ zero errorД¬onsider a V ernier callipers in which each 1 cm on the main scale is divided into 8 equal divisions and a screw gauge with 100 divisions on its circular scale. What is the thickness of the sheet if the main scale reading is 0.5 mm and the 25th division coincides with the main scale line ? Before starting the measurement, it is found that when the two jaws of the screw gauge are brought in contact, the 45th division coincides with the main scale line and that the zero of the main scale is barely visible. (2) In radio engineering a device for the exact tuning of radio receivers and other radio equipment.A screw gauge with a pitch of 0.5 mm and a circular scale with 50 divisions is used to measure the thickness of a thin sheet of Aluminium.

#Divisions on vernier scale plus#

If the zero line of the vernier (index) is located between the two lines c and c + 1 of the basic scale, then the reading is equal to c plus that indication of the vernier which is located opposite the line that best coincides with a certain line of the basic scale. The divisions of the vernier are figured in corresponding fractions of the division of the basic scale. If the interval between the divisions of the basic scale is represented by a, and the interval between divisions on the Vernier is ( a - a/n), then the vernier allows the primary scale to be read with an accuracy equal to 1/n of its division. The vernier is a movable scale that can slide along a fixed, basic scale the divisions on the movable scale are somewhat finer than those on the basic scale. The operation of the vernier is based on the eyeвЂ™s capacity to establish with certainty the coincidence of two lines when one of them is a continuation of the other and their ends overlap.
