Question

Describe the procedure to measure the diameter of a wire with the help of screw gauge

Answer 1

it is by tightening the mouth and when it full close to it the we can measure it

Answer 2

Answer:

1. find the least count ans the zero error of the screw gauge

Explanation:

1. turn the ratchet anticlockwise so as to obtain a gap between stud A and the flat end B placed wire in the gap between the stud A and the flat end B then turn the ratchet clockwise so as to hold the given while g a and the flat and B of the screw not the main scale reading note that division of the circular scale which on sides with the baseline of the main scale this circular scale division when X the least count gives the circular scale reading that is circular scale reading is equal to p into least count at the circular scale reading to the main scale reading to obtain the total readings that is observed diameter of the why repeat it by keeping the wire in perpendicular direction take two more observations at different places of the wild and record them in the table below ok
