ME ( Mechanical Engineering ) :
Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers research, design, develop, build, and test mechanical and thermal devices, including tools, engines, and machines.
Mechanical engineers typically do the following:
Analyze problems to see how mechanical and thermal devices might help solve the problem
Design or redesign mechanical and thermal devices using analysis and computer-aided design
Develop and test prototypes of devices they design
Analyze the test results and change the design as needed
Oversee the manufacturing process for the device
Mechanical engineers design power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines as well as power-using machines, such as refrigeration and air-conditioning systems.
Mechanical engineers design other machines inside buildings, such as elevators and escalators. They also design material-handling systems, such as conveyor systems and automated transfer stations.
Like other engineers, mechanical engineers use computers extensively. Computers help mechanical engineers create and analyze designs, run simulations and test how a machine is likely to work, and generate specifications for parts.
Employment of mechanical engineers is projected to grow 5 percent
from 2012 to 2022, slower than the average for all occupations. Job
prospects may be best for those who stay informed regarding the most
recent advances in technology. Mechanical engineers can work in many
industries and on many types of projects. As a result, their growth rate
will differ by the industries that employ them.Mechanical engineers should experience faster than average growth in architectural, engineering, and related services as companies continue to contract work from these firms. Mechanical engineers will also remain involved in various manufacturing industries—specifically, transportation equipment and machinery manufacturing. They will be needed to design the next generation of vehicles and vehicle systems, such as hybrid-electric cars and clean diesel automobiles. Machinery will continue to be in demand as machines replace more expensive human labor in various industries. This phenomenon in turn should drive demand for mechanical engineers who design industrial machinery.
Mechanical engineers are projected to experience faster than average growth in oil and gas extraction because of their knowledge and skills regarding thermal energy.
Mechanical engineers often work on the newest industrial pursuits. The fields of alternative energies, remanufacturing, and nanotechnology may offer new opportunities for occupational growth. Remanufacturing—rebuilding goods for use in a second life—holds promise because it reduces the cost of waste disposal. Training in remanufacturing may become common in mechanical engineering programs at colleges and universities.
Nanotechnology, which involves manipulating matter at the tiniest
levels, may affect employment for mechanical engineers because they
will be needed to design production projects based on this technology.
Nanotechnology will be useful in areas such as designing more powerful
computer chips and in healthcare.
