机械工程是物理原理和数学在创建有用的设备，对象和机器中的应用。机械工程师使用热，力以及质量和能量守恒等原理来分析静态和动态物理系统，从而为诸如汽车，飞机和其他车辆，供暖和制冷系统，家用等事物的设计做出贡献简而言之，机械工程师是社会的问题解决者。他们研究，开发，设计，制造和测试工具，引擎，机器和其他机械系统。他们还在发电机器上工作。他们开发机床，工业生产设备和机器人。机械工程师还设计其他工程师工作所需的工具。微机电系统和纳米技术的新兴领域涉及通过整合原子和分子来创建高性能的材料和组件，正在为设计过程引入全新
Mechanical Engineering is the application of physical principles and mathematics to the creation of useful devices, objects and machines. Mechanical engineers use principles such as heat, force, and the conservation of mass and energy to analyze static and dynamic physical systems, in contributing to the design of things, such as: automobiles, aircraft, and other vehicles, heating and cooling systems, household appliances, industrial equipment and machinery, weapons systems, etc. In brief, Mechanical Engineers are problem solver for the society. They research, develop, design, manufacture, and test tools, engines, machines, and other mechanical systems. They also work on power-producing machines. They develop machine tools, industrial production equipment, and robots. Mechanical engineers also design tools that other engineers need for their work. The emerging fields of Micro-Electro-Mechanical Systems and Nanotechnology, which involves the creation of high-performance materials and components by integrating atoms and molecules, is introducing entirely new principles to the design process. Social needs and new technologies and skills change the profession as it seeks to fit a wide-open global marketplace.
