2. A slip bush shown in the figure is to be manufactured. Prepare a production drawing incorporating the following requirements :

(i) Finish the inside (<j> 30) and outside (<|f 42) cylindrical surfaces to a roughness value of

0.8 nm. All the remaining surfaces are supposed to be a roughness value of 6.3 pim.

(ii) Outside diameter of tbeJbusk-skoa-iMwenft-concentricity tolerances of0.02~ffiffi. witli the axis of the cylindrical hole of <|> 30.

(iii) Inside diameter of the bush should have an upper and lower deviations of +0.028 mm. and +0.015 mm. respectively while the outside diameter has a tolerance of h 6. Redraw the given figure and indicate all the above informations on the drawing symbolically as per B.I.S.
