Holes $$1,2,3,4$$ drilled in sequence , with angular positions and tolerances are shown in Figure. Evaluate closing angle $$'X'$$ with its tolerance band.

The maximum interference in $$mm$$ after assembly between a bush of size $${30^{\matrix{ { + 0.06} \cr { + 0.03} \cr } }}$$ and a shaft of size $${30^{\matrix{ { + 0.04} \cr { - 0.02} \cr } }}$$ is

To obtain dimension of $$61.18$$ $$mm$$ using slip gages, the most appropriate combination is

$$A$$ $$30$$ $$mm$$ 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
