Problem
The main scale of a vernier callipers reads 10mm in 10 divisions. Ten divisions of the vernier scale coincide with nine divisions of the main scale. When the jaws touch, the fifth vernier division coincides with the ninth main-scale division, and the vernier zero is to the right of the main-scale zero. When a cylinder is tightly placed between the jaws, the vernier zero lies slightly to the left of 3.2cm and the fourth vernier division coincides with a main-scale division. Find the diameter of the cylinder.
