Question

The pitch of screw gauge is 1mm and there are 50 division or on CAP . when nothing is put between the stud . The zero of circular scale lie 6th division below the line of graduation. when a wire is palaced between the stud 3 linear scale division are clearly visible while 31 division or circular scale coincide with a reference line the diameter of wire is equal to ______.

please help kar do yar . it's very important ​

Answer 1

Answer:

9.62 mm

Explanation:

Given The pitch of screw gauge is 1 mm and there are 50 division or on CAP . when nothing is put between the stud . The zero of circular scale lie 6th division below the line of graduation. when a wire is placed between the stud 3 linear scale division are clearly visible while 31 division or circular scale coincide with a reference line the diameter of wire is equal to ______.

screw guage has 50 divisions on circular scale with pitch of 1 mm.

So 1 division is 1/50 mm

                             = 0.02 mm

Now we need to find the diameter

So 31 st division will be 0.02 x 31 = 0.62

So diameter = 3 + 0.62 + 6 mm

                     = 9.62 mm  

the diameter of wire is equal to 9.62 mm
