During my long experience in teaching several engineering subjects I noticed that many students find it difficult to learn from classical textbooks which are written as theoretical literature. They tend to read them as one might read a novel and fail to appreciate what is being set out in each section. The result is that the student ends his reading with a glorious feeling of knowing it all and with, in fact, no understanding of the subject whatsoever. To avoid this undesirable end a modern presentation has been adopted for this book. The subject has been presented in the form of solution of comprehensive examples in a step by step form. The example itself should contain three major parts, the first part is concerned with the definition of terms, the second part deals with a systematic derivation of equations to terminate the problem to its final stage, the third part is pertinent to the ability and skill in solving problems in a logical manner.

هي فرع هندسي يدرس الأنظمة الفيزيائية، ويطبق أسس القوانين الفيزيائية الأساسية لتحليلها. وإن أهم ما يميز علم الميكانيكا اعتماده على الرياضيات (بدلاً من التقدير) وعلى التجربة (بدلاً من الملاحظة)، حيث أسس كيفية صياغة التنبؤات الكمية نظرياً، وكيفية اختبار هذه الصياغات الرياضية بأدوات قياس مصممة بعناية.

و هي ايضا فرع هندسي يهتم بتصميم، وتصنيع، وتشغيل، وتطوير الآلات أو الأجهزة المستخدمة في مختلف قطاعات النشاطات الاقتصادية. وبتعريف الموسوعة البريطانية فإن الهندسة الميكانيكية هي فرع من فروع الهندسة تهتم بالتصميم والتطوير، وبالتصنيع، وبالتركيب، وتشغيل المحركات، والآلات، وعمليات التصنيع. وهي مهتمة بشكل خاص بالقوى والحركة. وهو علم يهتم بدراسة الطاقة بكافة صورها وتأثيرها على الأجسام. وهو تخصص واسع له علاقة بكل مجالات الحياة. فالهندسة الميكانيكية تتعلق مثلا بصناعات الفضاء، والطيران، وبالإنتاج، وتحويل الطاقة، وميكانيكا الأبنية، والنقل، وتكنولوجيا تكييف الهواء والتبريد، وفي النمذجة والمحاكاة المعلوماتية.


A special section for books in the field of mechanical engineering, "Mechanical engineering", which is an engineering branch that studies physical systems and applies the foundations of basic physical laws for analysis. The most important characteristic of mechanics is its dependence on mathematics (rather than estimation) and on experience (rather than observation), where it established how to formulate quantum predictions in theory, and how to test these mathematical formulas with carefully designed measurement tools.

"Mechanical engineering" is an engineering branch concerned with the design, manufacture, operation, and development of machines or devices used in various sectors of economic activities. By the definition of the British Encyclopedia, mechanical engineering is a branch of engineering concerned with design, development, manufacture, installation, and operation of engines, machines, and manufacturing processes. It is particularly interested in forces and movement. It is a science concerned with studying energy in all its forms and its effects on objects. It is a broad discipline related to all areas of life. Mechanical engineering is concerned with, for example, the aerospace, aviation, production, energy transformation, building mechanics, transportation, air conditioning and refrigeration technology, and in information modeling and simulatio
