Question

The pitch and the number of divisions, on the circular scale, for a given screw gauge are $0.5 mm$ and $100$ respectively. When the screw gauge is fully tightened without any object, the zero of its circular scale lies $3$ divisions below the mean line.

The readings of the main scale and the circular scale, for a thin sheet, are $5 .5 mm$ and $48$ respectively, the thickness of this sheet is:

Options:

Answer:

C

Solution:

least count $= \frac{0.5 m m}{100} = 0.005 m m$

Reading $= 5.5 m m + (48 - 3) \times 0.005 m m$

$= 5.725 m m .$

TestHub · Accepted Answer

least count = 0.5 m m 100 = 0.005 m m Reading = 5.5 m m + 48 - 3 × 0.005 m m = 5.725 m m .
