Question

The pitch of screw gauge is 1 mm and there are 100 divisions on the circular scale.in measuring the diameter of a sphere there are six divisions on the linear scale and 40 division on the circular scale coincide with the reference line . find the diameter of the sphere​

Answer 1

Answer:

6.40 mm

Explanation:

The pitch of screw gauge is 1 mm and there are 100 divisions on the circular scale.in measuring the diameter of a sphere there are six divisions on the linear scale and 40 division on the circular scale coincide with the reference line . find the diameter of the sphere​

100 Divisions = 1 mm

1 division = 1/100 = 0.01 mm

40 Divisions = 40 * 0.01 = 0.40 mm

Linear scale = 6 * 1 = 6 mm

Diameter of sphere = 6 + 0.40 mm  = 6.40 mm
