Mechanical engineering is a discipline of engineering that applies the principle of engineering, physics and material science for analysis, design, manufacturing , and maintenance of mechanical systems. It is the branch of engineering, that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines. The engineering field requires an understanding of core concepts including mechanics, thermodynamics, material science, structural analysis, and electricity. Mechanical engineers use computer aided engineering and product lifestyle management to design and analyze future manufacturing plants industrial equipment and machinery heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons etc. mechanical engineering’s development can be traced back several thousand years around the world. Mechanical engineering science emerged in the 19th century as a result of developments in the field of physics. The field has continually evolved to incorporate advancements in technology, and mechanical engineers today are pursuing developments in such fields as composites ,mechatronics, and nanotechnology. Mechanical engineering overlaps with aerospace engineering, civil engineering, electrical engineering, petroleum engineering, and manufacturing so, all of these are encountered and cannot be avoided. There are other fields mechanical engineers have to do like, biomedical engineering and modeling of biological systems like, soft tissue mechanics. Mechanical engineers have to design and build engines and power plants, structures and vehicles of all sizes. Mechanical engineering requires a bachelors degree.
The formal name for the degree is “Mechanical Engineer”, and the course work is based on five or six years of training, but in order to qualify as an Engineer you have to pass a state exam at the end of the course. Standards set participation to society and are intended to provide uniformity in fundamental subject material, promote competence among graduating engineers, and mostly to maintain confidence in the engineering profession as a whole. Students are required to show that they can “work professionally in both thermal and mechanical systems areas. Mechanical engineers are also expected to understand and be able to apply basic concepts from chemistry, physics, chemical engineering etc. All mechanical engineering programs include multiple semesters of mathematical classes including calculus, and advanced mathematical concepts. Also most mechanical engineering programs also require varying amounts of research or community projects to gain practical problem-solving experience. Engineers may seek license by a state, provincial, or national government. The purpose of this process is to ensure that engineers possess the necessary technical knowledge, real-world experience, and knowledge of the local legal system to practice engineering at a professional level. Once certified, the engineer is given the title of professional engineer. The field of mechanical engineering can be thought of as a collection of many mechanical engineering science disciplines. Several of these disciplines which are typically taught at the undergraduate level are listed below, with a brief explanation and the most common application of each. Some of these disciplines are unique to mechanical engineering, while others are a combination of mechanical engineering and one or more other disciplines.
