Engineering technology or mechanical engineering industry is the application of physical principles to create all kinds of machinery and equipment or other useful objects. Mechanical application of thermodynamic principles, the law of conservation of mass and energy to analyze static and dynamic physical systems, for design work in areas such as automotive, aircraft and the other vehicles, heating systems and cooling, household appliances, machinery and production equipment, weapons . Technology often creates mechanical simulator simulates the operation of objects, such as the actual manufacturing process in order to optimize performance, economic efficiency and energy costs before making choices select a.
