The pitch of a screw gauge is `0.5 mm` and there are `50` divisions on the circular scale. In measuring the thickness of a metal plate, there are five divisions on the pitch scale (or main scale) and thirty fourth divisions coincide with the reference line. Calculate the thickness of the metal plate.

Answer

B, D

Explanation

`LC = (0.5 mm)/(50) = 0.01 mm`
Thickness = `5 xx 0.5 mm + 34 xx 0.01 mm`
= `2.84 mm`.
