This book is a must-read for anyone preparing for civil service exams, construction exams, industrial complex exams, military exams, etc.
In particular, the difficulty of the problems has increased recently, and the pursuit of conceptual systematicity and establishment of basic theories are urgently required. Therefore, this study was organized based on this trend in questions.


- Features of this book -

① It was written based on many years of experience teaching at a mechanical engineering academy and past exam questions and exam criteria.
② We have faithfully organized the basic theories and concepts for each unit to ensure a comprehensive overview in a short period of time.
③ The direction of the problem flow was presented through relatively simple and easy explanations of the expected key questions from previous exams.
④ The problems adopted in this book are mainly those that are conceptually necessary or that can continue to be tested in the future, and the explanations also focus on establishing these main points.
⑤ In the appendix, we have provided recent exam questions as an opportunity for test takers to directly assess their own abilities.
