Two readings taken by a slip gauge on a flatness interferometer count 10 and 14 fringes. Second reading is obtained by rotating the set up at 180°. Assuming the wavelength of radiation is 0.8065 μm, the parallelism error b/w two faces of slip gauge is

Match the List-I (Measuring instruments) with List-II (Applications) and select the correct from the codes given in the lists below:

A hole of nominal diameter 30 mm with a hole tolerance of ± 0.020 mm is used to design a GO – NO GO plug gauge. If gauge tolerance is 10 % of work tolerance and no wear condition, the dimension of GO plug gauge as per unilateral tolerance system is

A cylindrical standard of 31.5 mm diameter and two wires of 2 mm diameter each used to measure the effective diameter of an external metric thread having included angle as 60° and pitch 4.5 mm. If the micrometer reading over the standard wires are 17.532 mm and 16.398 mm. What is the effective diameter (mm) of thread?

A graph is drawn to a vertical magnification of 10000 and horizontal magnification of 100, and the areas above and below the datum line are as follows:
