Fundamentally, mechanical engineers are involved with the mechanics of motion and the transfer of energy from one form to another or one place to another. Mechanical engineers design and build machines for industrial and consumer use -- virtually any machine you find, had a mechanical engineer involved with its development and production. They design heating, ventilation, and air conditioning systems to control the climate in homes, offices, and industrial plants, and develop refrigeration systems for the food industry.

We live in a world of dependent on the production and conversion of energy into useful forms. Mechanical engineers are involved in all aspects of the production and conversion of energy from one form to another. They design and operate fossil fuel, hydroelectric, conventional, nuclear and cogeneration power plants. They design and develop internal combustion engines for automobiles, trucks and marine use and also for electrical power generation.

Mechanical engineers are experts on the conversion and use of existing energy sources and in developing the equipment needed to process and transport fuels. At the same time, mechanical engineers are active in finding and developing new forms of energy. In that effort, mechanical engineers deal with the production of energy from alternate sources, such as solar, geothermal, and wind.

Working in project teams is a way of life for mechanical engineers. Deciding which projects to undertake and leading those projects to a successful conclusion is the job of experienced engineers who move into management. On the safety front, all projects involve safety issues. By its very nature mechanical engineering involves the harnessing and channeling of the forces of nature, forces which are often extremely powerful.

Transportation is a large and growing field for mechanical engineers. Existing modes of air and surface transport require continuous improvement or replacement. Mechanical engineers work at the cutting edge of these efforts. Wherever machines are made or used, you will find mechanical engineers. They are instrumental in the design, development and manufacturing of machines that transmit power.

In contemporary manufacturing companies, mechanical engineers play a key role in the "realization" of products, working closely with other engineers and specialists in corporate management, finance, marketing, and packaging. Mechanical engineers design products, select materials and processes, and convert them to finished products. They design and manufacture machine tools -- literally the machines that make machines and design entire manufacturing processes, aided by the latest technologies in automation and robotics.

In order to arrive at the best design for a product, mechanical engineers use a wide variety of metal, plastic, ceramic materials. They also use composites made up of more than one type of material. Once designed, built and in service, elements like pipeline welds and sections, gears and other drive-train elements may need inspection for structural integrity or the effects of mechanical wear.

As a structural engineer, you will face the challenge of designing structures that support their own weight and the loads they carry, and that resist wind, temperature, earthquake, and many other forces. Bridges, buildings, and many other kinds of projects are included within this exciting discipline. You will develop the appropriate combination of steel, concrete, timber, plastic, and new exotic materials.

In this field, you may be called upon to resolve issues of providing safe drinking water, cleaning up sites contaminated with hazardous materials, disposing of wastewater, and managing solid wastes.

Geotechnical engineering is required in all aspects of civil engineering, because the ground supports most projects. As a geotechnical engineer, you might develop projects below ground, such as tunnels, foundations, and offshore platforms. You will analyze the properties of soil and rock that support and affect the behavior of these structures. You may evaluate the potential settlements of buildings, the stability of slopes and fills, and the seepage of ground water and the effects of earthquakes.

Water is essential to our lives, and as a water resources engineer, you will deal with issues concerning the quality and quantity of water. You will work to prevent floods, to supply water for cities, industry, and irrigation, to treat wastewater, to protect beaches, or to manage and redirect rivers. You might be involved in the design, construction, or maintenance of hydroelectric power facilities, canals, dams, pipelines, pumping stations, locks, or seaport facilities.

Because the quality of a community I directly related to the quality of its transportation system, your function as a transportation engineer will be to move people, good, and materials safely and efficiently. Your challenge will be to find ways to meet our ever-increasing travel needs on land, air, and sea. You will design, construct, and maintain all types of transportation facilities, including highways, railroads, airfields, and ports.

As a construction engineer, you are the builder of our future. The construction phase of a project represents the first tangible result of design. Using your technical and management skills will allow you to turn designs into reality - on time and within budget. You will apply your knowledge of construction methods and equipment, along with the principles of financing, planning, and managing.

As a professional in this area, you will be concerned with the entire development of a community. Analyzing a variety of information will help you coordinate projects, such as projecting street patters, identifying park and recreation areas, and determining areas for industrial and residential growth. To ensure ready access to your community, coordination with other authorities may be required to integrate freeways, airports, and other related facilities.
