Question

The pitch of a screw gauge is p, and there are 100 divisions on its circular scale. When there is nothing between the jaws, the instrument reads 5 divisions. In measuring the diameter of a wire, there are 6 divisions on the main scale, and x divisions coincide with the main scale. Then the diameter of the wire is:

Options:
a. p+6x/500​
b. p+x6/100​
c. p+600/x​
d. p+100x/6​

Answer 1

The diameter of the wire can be calculated using the formula p + (6x/100), where p is the pitch and x is the number of divisions coinciding with the main scale.

Step-by-step explanation:

To determine the diameter of the wire using the screw gauge, we need to understand its readings. The screw gauge has a pitch of p and 100 divisions on its circular scale. With nothing between the jaws, it reads 5 divisions. When measuring the wire, there are 6 divisions on the main scale, and x divisions coincide with the main scale. The formula to calculate the diameter of the wire is given as:

diameter of wire = p + (6x/100)
