Question

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 divisions Given that 1 mm on the main scale corresponds to 100 divisions of the circular scale. The diameter of the wire from the above data is, 0 . 052 cm, 0 . 026 cm, 0 . 005 cm, 0 . 52 cm

MARKS App · Accepted Answer

Diameter of wire, d = M S R + C S R × L C = 0 + 52 × 1 100 = 0.52 m m = 0.052 c m .
