ESE 2021 Mains Mechanical Engineering Conventional Paper 2 Previous Conventional Questions with Solutions, Subject wise and Chapter wise

In UPSC Engineering Services, Conventional Papers have 54.5% weightage in the entire process of written test.
In Paper-II of Mechanical Engineering Nine subjects are included as follows:
01. Production Engineering                             02. Strength of Materials
03. Theory of Machines                                   04. Machine Design
05. Industrial Engineering                               06.Engineering Materials
07. Maintenance Engineering                           08. Engineering Mechanics
The following approach is advisable to secure maximum marks.
1) The solution to any question shall have the following appropriate steps generally. Steps will also have due weightage.
   (a) The data given
   (b) The appropriate figure, if applicable, with parts labeled properly
   (c) The concept on which the problem is being solved
   (d) The relevant formulae with standard Notations and abbreviations. Incase the paper setter asks to solve the question from the fundamentals, necessary derivations shall be done. Otherwise 70% of marks one has to lose. If the question carries more marks like 10 to 20 marks detailed analysis is compulsory to score high. If the question carries less marks (<8) the formulae with abbreviations and concepts may be sufficient. In any case, the assumptions made shall be written clearly while solving a problem.
2) The neatness and presentation of solutions will have 5% marks.
3) Note that all parts of a question shall be answered together.
4) Using short sentences and brevity in expressing the content is appreciat
