A screw gauge gives the following reading when used to measure the diameter of a wire.Main scale reading : 0 mm Circular scale reading : 52 divisionsGiven that 1 mm on main scale corresponds to 100 divisions of the circular scale.The diameter of wire from the above data is:

Solution & Step-by-step Explanation

1. Calculate Least Count (LC): LC = \frac{Pitch}{Number of circular scale divisions} = \frac{1 mm}{100} = 0.01 mm 2. Total Reading: Reading = MSR + (CSR \times LC) Reading = 0 mm + (52 \times 0.01 mm) = 0.52 mm 3. Convert to cm: 0.52 mm = 0.052 cm

Try it yourself before checking the explanation above.
