ESE-2019 General Studies And Engineering Aptitude Previous Years Objective Questions with Solutions, Subject wise (2017-2018)₹ 150
Engineering Services is one of the most prestigious examinations conducted in the country for recruitment of engineers in various Central Government Organisations. The depth and Breath of subject knowledge needed to perform in ESE definitely cut above compared to other similar examinations conducted by any agency that recruits engineers. Nature of work of engineers entering services through ESE involves timely application of both technical and managerial skills. Questions in ESE test the candidates not only in fundamentals but also the ability for application of concepts in a wider aspect. Therefore the candidate who intends to crack ESE shall have to be double edged in terms of being strong in fundamental concepts and a certain definite levels of application of the concepts as well. This demand makes success in ESE more challenging.
In the latest pattern of examination of ESE, the scope of preparation has extended to engineering Aptitude in addition to the engineering learned in the college. This round has become crucial for moving to the next round since ranking in ESE includes performance in all rounds now. An aspiring candidate is now demanded to prepare not just in engineering aspects of the subject. In addition, one has to prepare well in the approach to solving the problems, which is termed the Engineering aptitude, for a maximum of 200 marks. This approach to engineering tests the candidates in a range of subjects that includes essential mathematical approach, desirable characteristic tarits as engineers through professional ethics, skills using information communication technologies, Design for safety, Environmental concerns, among others.

While Engineering Marvels make lives of people better, accidents and disasters pose challenges to engineers in edition to affecting the public. A deeper investigations of these mishaps leads to pointing the finger on the conduct of engineers, their inability to either identify or resolve the identified moral issues in an appropriate manner. While sometime this inability can be traced to incompetence, majority of the times it turns out to be the pressure by the management whose priorities differ from that of the professional engineers. The engineer is pressed to handle these two factors along with his/her own ignorance or arrogance, to make sure that public is not victimized.
Therefore, there is a need to expose the engineering students to the ethical considerations of engineering problems in edition to the technologies and standards taught in engineering education. While curriculum focuses on external engineering aspects in terms of meeting standards, facilitating practice of ethical conduct focuses on inner engineering and inculcates and nurtures the sense of responsibility and accountability in the engineering graduates. This further promotes integrity in the qualified engineers to conduct profession in the most ethical manner. This dimension of engineering education that gives inputs on the ‘third dimension’ of engineering, viz., values of engineering profession can be termed as engineering aptitude.
UPSC Conducts engineering services to recruit engineering graduates in various technical departments every year. From 2017onwards UPSC has included editional filter in the recruitments process for the candidates that tests them in engineering aptitude. ACE Engineering Academy, through its expertise has been in the forefront in training the candidates, giving them the critical tool of competence to get competitive advantage and perform better and excel in their career. One of the topics in engineering aptitude, “Ethics and Values in Engineering profession”, was conceived and curriculum delevopled to train the candidates. It is matter of satisfaction and pride that some of the practice questions and discussions held in the classroom teaching appeared in the ESE question papers.ACE is proud of its impactful and effective traning system that gave comfort and confidence to its candidates in the examination hall. This third edition is next step in pursuit of excellence in making the content further more relevant, comprehensive that can catalyze the performance of the candidates in the UPSC examination. Redundancy is at its minimum by way of providing all the relevant information in one place in this edition. Context fitting examples, illustrations, case studies and pictorial representation of some abstract concepts are some of the hallmarks incorporated in this edition. Some of the case studies and illustrations that were discussed in the classrooms have been incorporated in this book with the aim of making these discussions available to the candidates who cannot make it to classrooms. Authors are of the firm conviction that students would enjoy not only reading this new book but also content relevant practice questions included in the career. This edition is markedly different from previous editions with content relevant practice questions included in the appropriate places. Another deviation of this edition from previous editions is inclusion of previous ESE questions.
Authors have attempted sincerely to make this edition as error free as possible. Still some inadvertent mistakes could crept in but these are purely unintentional.

We proudly say that questions ands solutions right from 1992 onwards are given in this book. The questions which appeared in early 90’s are most conceptual oriented and these are being repeated in the recent exams in a different way. Hence, we advise the students to practice these questions compulsorily. 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 frames, recall the relevant equations, Find 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 answer. The student is advised to have a standard text book ready 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. By doing so, one loses an opportunity of effective revision.

I would like to welcome you all to yet another net worthy effort by ACE engineering publications for engineering services aspirants to learn, understand and appreciate the subject and quality practices in Production, construction Maintenance and services.
The key factors that are responsible for survival and performance excellence of any industry are customer satisfaction and return on the capital invested. This applies to both manufacturing and service sectors. To avoid intra country and inter country comparisons for products in the market, there arises a need for uniformity in standards, established codes and procedures for meeting customer expectations. Hence the standards and quality practices play an important ole. For this requirement to be met ISO is ensuring equality in the standards of products and services.
ISO is striving relentlessly to institute quality policies to shape the behaviour and establish core values in an organisation and therefore contribute to corporate policy, control charts. Acceptance sampling systems, continuous improvement techniques are used by every organisation throughout the world to improve product quality service quality and reduce cost. The most effective use of these techniques depends upon they being understood by production and inspection supervisors by engineers and by managements.
Rules and regulations for improving quality in all disciplines was documented by quality guru’s in the quality philosophers, which are advocated throught out the world.
We tired our level best in the first attempt to give the best possible theory with relevant objective questions. You know there is no end for the best . It is process. We welcome the suggestions by readers with respect to content and questions. Any mistakes typographical/others may please be brought to the notice of us, for which we will be grateful to you.
