AMIE Section B in Mechanical Engineering is the advanced, specialisation stage of the Institution of Engineers (India) professional examination route to engineering qualification. Candidates typically reach it after completing the Section A foundation stage, and it suits working technicians, diploma holders and self-taught engineers who want a recognised mechanical engineering credential without leaving employment. The AMIE Section B Mechanical case studies are 5 cases and about 3,565 words.
1Motor Bracket Weldment: Tolerance Stack and Drawing Interpretation
A pump motor bracket is fabricated from a 12 mm thick mild-steel plate welded to a hub. The drawing gives the hub bore as 40.00/40.05 mm and the motor shaft as 39.94/39.98 mm.
