What Would I Do?

Mechanical Engineers* research, design, manufacture, and test aircraft, vehicles, biomedical instruments, manufacturing equipment, computer systems and components, and other mechanical devices.

Mechanical engineering is one of the broadest engineering disciplines. Mechanical Engineers apply the principles of science and mathematics to work on power-producing machines, for example, electric generators; internal combustion engines; fuel cells; wind, steam, and gas turbines; solar photovoltaic and solar thermal systems; and energy storage devices, such as hybrid vehicle batteries. They also work on power-using machines, such as machine tools, material-handling systems, elevators and escalators, industrial production equipment, and robots used in manufacturing. Engineers may design heating, ventilation, and air-conditioning (HVAC) or water systems to improve energy efficiency. Engineers may also evaluate designs for energy performance or environmental impact and make sure products meet design and performance requirements or environmental regulations.

Automotive Engineers develop new or improved designs and specifications for vehicle structural supports, engines, transmissions, and other vehicle systems, such as automotive energy management, alternate fuels, or hybrid power, using computer-aided design (CAD) technology. They may design vehicles that use lighter materials, such as aluminum, magnesium, alloy, or plastic, to improve fuel efficiency. They also generate cost estimates for automotive design concepts, as well as direct the building, modification, and testing of vehicles and their components.

Fuel Cell Engineers design, modify, and construct fuel cell systems, subsystems (for example, humidifiers and blowers), assemblies, or components for transportation, stationary, portable, or military applications. They develop processes to separate components of liquids or gases or to generate electrical currents using controlled chemical processes. Fuel Cell Engineers evaluate equipment and processes to identify ways to maximize performance and to ensure compliance with safety and environmental regulations. They conduct fuel cell testing projects using fuel cell test stations, analytical instruments, or electromechanical diagnostics to calculate the efficiency and power output of a fuel cell system or process. They monitor and assess performance of full-scale fuel cell systems and their degradation over time in order to analyze the data for efficiency. Fuel Cell Engineers need to be knowledgeable of Proton Exchange Membrane (PEM) fuel cell systems and associated fuels. In addition, knowledge of thermodynamics, heat transfer, and fluid flow analysis is vital in optimizing fuel cell systems.

Tools and Technology

Mechanical Engineers use a variety of tools and technology in the course of their work, such as combustion analyzers, flowmeters, optical laser scanners, pressure gauges, vibration isolators, and software including analytic, scientific, or statistical; computer-aided design (CAD); cost estimation; and project management.

Green Economy

Mechanical Engineers will play an important role in the emerging green economy. Some will assist with the research and design of renewable energy components or energy-efficient systems. Others will work on green construction technology or transportation-related solutions to reduce environmental impacts.

Working Conditions

Most Mechanical Engineers work in office buildings, laboratories, or industrial plants. Since this is often a 'hands-on' occupation, they may spend considerable time on factory floors where it can be noisy and hot. They may also be required to be trained in proper safety procedures and may wear protective equipment, such as hard hats, safety glasses, or hearing protection. Some Engineers travel to worksites in the United States or abroad.

Engineers generally work a 40-hour week; however, deadlines may bring extra pressure to a job, requiring longer work hours, which may include weekends and holidays.

Mechanical Engineers are typically not members of labor organizations; however, Engineers who work for government agencies may belong to a union.

Will This Job Fit Me?

Mechanical engineering may appeal to those who enjoy working with ideas and activities that require an extensive amount of thinking and include practical, hands-on problems and solutions.

Aspiring Engineers should be creative, inquisitive, analytical, detail oriented, and like working with tools and machinery. They must be able to work independently as well as part of a team. Effective oral and written communication skills are critical.
