ESE-2024 UPSC Preliminary Examination Mechanical Engineering Objective: Volume 1

Dear Students,

Currently, the Stage-I (Prelims) of ESE (Mechanical Engineering) consists of two objective papers. Paper -I is for General Studies & Engineering Aptitude, while Paper-II is of Mechanical Engineering for 300 Marks and for 3 hours duration. In stage-II (Mains) Mechanical Engineering, the technical syllabus is divided into two papers which contain Conventional Questions.

The Objective Questions included in this volume are for the following subjects only.
1. Thermal Engineering & Renewable Sources of Energy    2. Heat Transfer
3. Fluid Mechanics                                                                     4. Turbo Machinery

Based on the new pattern for prelims, Volume-I is redesigned using the previous questions from 1992 onwards for the above mentioned subjects.
The style, quality and content of the Solutions for previous ESE Questions of Mechanical Engineering, will Encourage the reader, especially the student whether above average, average or below average to learn the concept and answer the question in the subject without any tension.  However, it is the reader who should confirm this and any comments and suggestions regarding this would be warmly received by the Academy.  It is observed that majority of ESE objective Questions are being asked as it is, in many PSUs, state service commissions, state electricity boards and even in GATE exam. Hence, we strongly recommend all students who are competing for various competitive exams to use this book according to the syllabus of the exam concerned. This book can also be used by fresh Teachers in engineering colleges to improve their Concepts.

We proudly say that questions and solutions right from 1992 onwards are given in this book. The questions which appeared in early 90’s are more conceptually oriented and these are being repeated in the recent exams in a different way. Hence, we advice the students to practice these questions rigorously. The student is also advised to analyze why only a particular option is correct and why others are not. Evaluate yourself, in which case, these other options are correct. With this approach you yourself can develop four questions out of one question. The student is advised to solve the problems without referring to the solutions. The student has to analyze the given question carefully, identify the concept on which it is framed, recall the relevant equations, finds out the desired answer, verify the answer with the final key such as (a), (b), (c), (d), then go through the hints to clarify his/her doubt, if any. The student is advised to have a standard text for reference to strengthen the related concepts, if necessary. The student is further advised not to write the solution steps in the space around the question because of difficulty in effective revision.
