Answer 1

Q. 2. 2) a surfaus require finishing for ² 3) The tolerance is permitted on dimensions which do not specify a wrtain dimensions are 10.02 for 2 decimal dimension & +0.005 for 3 decimal dimensions %) - +0.7522 6) 7 Holes are there - Maximum certre to Centre distance between the holes is burits. 8) Outer surface finish / Flat surface finish of the circular portion require surfare finish. 9) & The limit dimensions for larger hole 0.1518 tot 10) Maximun Permissible wall Thickness at largerhole is 0.499 11) Mirinun Pornissible Wall Thickness at smaller hole is 0.3741 14 The height of the larger shaft support is 0.499 f. of the smaller shaft support is 0.3741. 13) Require additional data for LN3 type fit 14) Reaning & Honing Process will give read. surface finish. 15) Nominal size is $0.34 16) Allen Screw 17) Read distance is 0.35 18 No A4 B found in part 2
