Mechanical engineering is the field of technology that deals with engines, machines, tools, and other mechanical devices and systems. This broad field of innovation, design, and production deals with machines that generate and use power, such as electric generators, motors, internal combustion engines, and turbines for power plants, as well as heating, ventilation, air-conditioning, and refrigeration systems. In many universities, mechanical engineering is integrated with nuclear, materials, aerospace, and biomedical engineering. If you are looking for a research starter about this topic, click here!
