A straight edge is inspected on a coordinate measuring machine. The readings obtained at intervals of $$100mm$$ along the top edge are $$100.01, 100.05, $$ and $$100.04$$ $$mm$$ the straightness error, making the end points as reference, is ....... $$mm$$

In an interference microscope, a groove produces a band distortion of $$4$$ band spacing. If the wave length of the monochromatic light source is $$0.5microns,$$ the groove depth is ......................$$mm$$

Powder metallurgical components have

$$A$$ $$30$$ $$mm$$ hole shaft assembly results in minimum and maximum clearances of $$0.03$$ $$mm$$ and $$0.30$$ $$mm$$ respectively. The hole has a unilateral tolerance with zero fundamental deviation. If the tolerance on the shaft is $$0.08$$ $$mm,$$ the maximum size of the hole is
