A screw has a pitch equal to 0.5 mm. What should be the number of divisions on its head so as to read correct up to 0.001 mm with its help ?
A screw gauge was found to have a pitch equal to 0.8 mm. What should be the number of divisions on its head so that you can read up to 0.001 cm using this?
A screw gauge has a pitch of 1 mm. What should be the number of divisions on its head so that the smallest measurement that can be made using this is 0.001 cm?
When a screw gauge with a least count of 0.01 mm is used to measure the diameter of a wire, the reading on the pitch scale is found to be 0.5 mm and the reading on the head scale is 27 divisions. If the zero error is +0.005 cm, what is the diameter of the wire?
A screw gauge with a least count of 0.01 mm is used to measure the diameter of a lead shot. The reading on the pitch scale is found to be 1 mm and the reading on the head scale is 40 divisions. If the screw gauge has a zero error of – 0.05 mm, what is the surface area of the lead shot?
