Answer the following : (b) A screw gauge has a pitch of 1.0 mm and 200 divisions on the circular scale. Do you think it is possible to increase the accuracy of the screw gauge arbitrarily by increasing the number of divisions on the circular scale ?
It is not possible to increase the accuracy of a screw gauge by increasing the number of divisions of the circular scale. Increasing the number of divisions of the circular scale will increase its accuracy to a certain extent only.
