Question

Find the thickness of a five rupee coin with the screw gauge, if the pitch scale reading is 1 mm and its head scale coincidence is 68.

Answer 1

Considering that the least count of the Screw Gauge is 0.01 mm. Now we find the thickness of the coin by using the formula,

 

The Thickness of the coin is = (Pitch scale reading + least count * Coincident head scale reading)

                                            = (0.1 cm + (0.01 mm * 68))

                                            =0.168 cm
