Definition of mechanical engineer:
According Jonathan Wickert & Kemper Lewis: Mechanical engineers research, develop, design, manufacture and test tools, engines, machines, and other mechanical devices. They work on power-producing machines such as electricity-producing generators, internal combustion engines, steam and gas turbines, and jet and rocket engines. They also develop power using machines such as refrigeration and air-conditioning equipment, robots used in manufacturing, machine tools, materials handling systems, and industrial production equipment.
Mechanical engineers are known for their broad scope of expertise and for working on a wide range of machines. Just a few examples include the micro electro-mechanical acceleration sensors used in automobile air bags; heating, ventilation, and air-conditioning systems in office buildings; heavy off-road construction equipment; hybrid gas-electric vehicles; gears, bearings, and other machine components; artificial hip implants; deep-sea research vessels; robotic manufacturing systems; replacement heart valves; noninvasive equipment for detecting explosives; and interplanetary exploration spacecraft.
Mechanical Engineering’s Top Ten Achievements:
Mechanical engineering isn’t all about numbers, calculations, computers, gears, and grease. At its heart, the profession is driven by the desire to advance society through technology. The American Society of Mechanical Engineers (ASME) surveyed its members to identify the major accomplishments of mechanical engineers. This professional society is the primary organization that represents and serves the mechanical engineering community in the United States and internationally.
This top ten list of achievements, summarized below, which can help you better understand who mechanical engineers are and appreciate the contributions they have made to your world. In descending order of the accomplishment’s perceived impact on society, the following milestones were recognized in the survey:
1. The automobile
2. The Apollo program
3. Power generation
4. Agricultural mechanization
5. The airplane
6. Integrated-circuit mass production
7. Air conditioning and refrigeration
8. Computer-aided engineering technology
10. Codes and standards
