The importance of mechanical engineering in our daily lives is summarized as follows:
1- Work in the field of design and supervision of mechanical services for facilities, including air conditioning, heating, cooling and drainage systems, fire fighting, and industrial security and safety.
2- Maintenance and operation of machines, whether in the civil or military sector.
3- Participation in the operation and maintenance of power generation plants.
4- Operating and monitoring production lines in the industrial field.
Engineering mechanics is concerned with the study of the theoretical and laboratory effects of force, stress, and motion applied to engineering and construction materials. Scientific subjects are concerned with studying the evolution of matter, its manufacture, chemical composition, properties, and microscopic composition. The study of materials depends mainly on studying the structural composition of these materials.
