Question

When the tip of the screw of a screw gauge is in
contact with the stud, the zero of the circular scale
is 3 divisions below the index line. To hold a wire
the thimble is given a little over 3 rotations in the
anti-clockwise direction and with wire held tightly
the 32nd division of the circular scale is now in
line with the base line. The pitch of the screw is
0.5 mm and the number of divisions on the circu-
lar scale are 100. Find the correct diameter of the
wire.​
