A screw gauge with a pitch of 0.5 mm and a circular scale with 50 divisions is used to measure the thickness of a thin sheet of Aluminium. Before starting the measurement , it is found that when the two jaws of the screw gauge are brought in contact, the 45th division coincides with the main scale line and that the zero of the main scale is barely visible. What is the thickness of the sheet if the main scale reading is 0.5 mm and the 25th division coincides with the main scale line ?view Lecture 4 : Basic tools and apparatus (Contd.) created on Sat, 06/13/2020 - 14:58
Diameter of a ball is measured using a vernier calipers. It has divisions of 0.1cm on its main scale (MS) and 10 divisions of its vernier scale (VS) match 9 divisions on the main scale. If main scale reading is 0.8 cm and vernier coincidence is 6, calculate the radius of the ball.view Lecture 3 : Basic tools and apparatus (Contd.) created on Sat, 06/13/2020 - 14:10
