The field of mechanical engineering covers the areas of: mechanics, robotics, fluid dynamics, environmental science, thermal engineering, IC engineering, machine tool design, and plastics, etc. Measurement units such as heat, force, torque, horsepower, stress, and strain are used and studied in the field of mechanical engineering. Mechanical engineers study various things such as technical, social, environmental and economic problems and try to find mechanical solutions to the problems. These people may design a process, a product, a component or a machine to achieve this.
Mechanical engineering is a precise art as very detailed calculation goes into the design and building of things such as automobiles, airplanes, and machine tools, etc. Mechanical engineers use computer-aided, design software packages to quickly create simulations and 3D models of their projects. The principle of thermodynamics is used to create gas turbines, and IC engines that are used in automobiles, etc.
The list of machinery that is used in mechanical engineering is endless as mechanical engineering principles are used in such a large number of different industrial areas. Electronic and electrical systems are closely integrated to make intelligent systems. Devices such as robots use mechanical and hydraulic elements in addition to the processor and digital circuits. While material engineering helps in choosing the right materials and electric and electronic engineering systems provide the logic and power, it is mechanical engineering that helps the devices perform.
There are various sectors that make up mechanical engineering such as research and development, product design, manufacturing, systems management, sales and marketing. If a person combines all of these things successfully they may be able to become an: automotive engineer, biomedical engineer, consultant, heating, ventilation, and air conditioning (HVAC) engineer, nuclear engineer, or robotics engineer.
Mechanical engineering is a very specialized field and it often takes years of hard work, training and studying for a person to become a good mechanical engineer. Because mechanical engineering covers such a wide range of topics, most mechanical engineers have an interest in a variety of areas such as the liberal arts, humanities, writing, science, calculus, chemistry, physics, biology, and mechanical drawing or drafting.
