Introduction to Mechanical Engineering
Mechanical Engineering The field of mechanical engineering, as one of the oldest and most basic branches of engineering sciences, has made a significant contribution to the emergence of tools, structures, inventions and innovations, as well as has greatly improved human progress and his understanding of his environment. The science of mechanics, which dates back to the invention of the wheel and the manufacture of basic tools needed by humans, was developed in the following centuries by Newton and Galileo, and in parallel with the Industrial Revolution in Europe, mechanical engineering as a discipline was studied by researchers; To the extent that human inventions in some fields were somehow related to mechanics. Today, this field and mechanical engineers play a significant role in the development and dynamism of the country.
The main topics and topics of mechanical engineering are: statics, dynamics, materials mechanics, thermodynamics, fluid mechanics, fluid dynamics, heat transfer, vibrations, component design , Machine design, electrical and electronic circuits, car dynamics, measurement systems, control theory and control systems including hydraulic control systems, pneumatic control systems, vibration control systems and mechatronic control systems.

Mechanical students at all levels are heavily involved with specialized topics in mathematics and physics and, in some cases, chemistry. For this reason, studying in this field is not recommended for people who consider themselves extremely weak in these areas. In addition, courses such as "material strength", "thermodynamics", "fluid mechanics", etc. have analytical complexities just like the same mathematics courses. On the other hand, this field of engineering, especially in our country, has a direct relationship with practical work experience; A successful mechanical engineer is one who can strive to gain similar experiences during his or her studies. Incidentally, working in the field of mechanical engineering in many cases requires experience and knowledge in other fields. For example, manufacturing engineers who specialize in the molding profession must be fully acquainted with metallurgy and the properties of materials. They must be able to make good use of materials science handbooks or resources such as the "Steel Key".

Mechanical Engineering majors at the undergraduate level:
In the resolution of the 474th session of the Higher Education Planning Council of the Ministry of Science, Research and Technology dated 10/19/88, the different trends in the field of mechanical engineering were defined as eleven specialized tables that students can choose based on personal interest and labor market needs. Choose and pass 15 credits from each major. These trends are:
Solid Mechanics, Dynamic and Control Systems, Manufacturing, Mechanical Design, Heat and Fluids, Power Plants and Energy, Facilities, Automotive, Aerospace, Biomechanics, Mechatronics

Fields of activity in mechanical engineering
In a general division, the fields of activity of mechanical engineers can be classified into the following categories:
Design: Machines and devices that make and package any type of product, rotating equipment such as pumps, compressors, blowers, turbomachines (turbines, etc.), internal combustion engines, pressure vessels, reactors, heat exchangers, exchangers Piping systems, vehicles such as cars, trucks, buses, airplanes, trains, etc., material handling equipment such as conveyors, robots, and controller design for dynamic systems.

Analysis: failure and wear of devices, improving the performance and reliability of components, heat transfer systems, mechanical vibrations, acoustic and piezoelectric.

Manufacturing: Manufacturing plastic injection molds, press metal molds, matrix holes and seals, manufacturing industrial parts and manufacturing machines in small and large dimensions.

Quality control: testing the quality, safety and reliability of products, devices and processes, in the field of manufacturing processes, traditional machining processes, non-traditional machining processes, forming processes including sheet and volumetric forming, design and manufacture of molds and constraints, connection methods and Welding, heat treatment, casting methods, metrology and measurement systems, nanotechnology, microelectromechanical systems (sensing and operating), nanoscale drug delivery systems, micro and nanofluid systems, nanorobots and collaboration with other civil engineers, such as electrical engineering Chemistry, etc.) in order to design units that produce various types of products.

Mechanical engineering software
Familiarity with engineering software is one of the prerequisites for success in mechanical engineering. In the early seventies, even the most basic activities in this field were done only with the help of pen, paper and calculator. But with the pervasive use of computers and the advent of AutoCAD software, the first steps were taken to advance software in the field of mechanical engineering. Now other students could design their own engineering drawings using this software, and for this reason, the birth of AutoCAD was a turning point in the work of students and experts in the field. It was after AutoCAD that analytical and computational software came to the aid of mechanical engineers. Today, however, the work has reached a point where being a mechanical engineer without complete mastery of at least three or four specialized software is no more than a claim. Some of the well-known software in this field are:

Nisa : Parts design software
pro-engineer: Parts design software
Marc : Forces and stress analysis software
Ansys : Software for component engineering analysis in dynamic analysis
Catia Parts design software
Fluent Fluid analysis software
Matlab:Software for writing mathematical programs and calculations in engineering
