the least count of the main scale of a screw gauge is 1 mm. the minimum number of divisions on its circular scale required to measure 5`mu m` diameter of a wire is :
Accuracy of screw gauge can be increased by …………. The number of divisions on circular scale.
Pitch of a screw gauge is 0.5 mm and its least count is .01 mm, Calculate no. of divisons on its circular scale.
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 ?
Two full turns of the circular scale of a screw gauge cover a distance of 1mm on its main scale. The total number of divisions on the circular scale is 50 . Further, it is found that the screw gauge has a zero error of - 0.03mm . While main scale reading of 3mm and the number of circular scale divisions in line with the main scale as 35 . the dimeter of the wire is
A screw gauge has 1.0mm pitch and 200 divisions on the ciruclar scale. The least count of the instrument is
Two full turns of the circular scale of a screw gauge cover a distance of 1 mn on its its main scale . The total number of divisions on the circular scale is 50. Further m it is found that the screw gauge has a zero error of - 0.02 mm . While measuring the diameter of a thin wire , a student notes the main scale reading of 4 mm and the number of circular scale divisions in line with the main scale as 37. The diameter of the wire is
The pitch of a screw gauge is a mm and there are 100 division on the circular scale. While measuring the diameter of a wire, the linear scale reads 1mm and 47th division on circular scale coincides with the reference line. The length of the wire is 5.6 cm. Find the curved surface area (in cm^2) of the wire in proper significant figures.
