Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches.
The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. It is the branch of engineering that involves the design, production, and operation of machinery.
Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. In the 19th century, developments in physics led to the development of mechanical engineering science. The field has continually evolved to incorporate advancements; today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, structural engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. Mechanical engineers may also work in the field of biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology, and modelling of biological systems.
Electrical engineeringis anengineeringdiscipline concerned with the study, design, and application of equipment, devices, and systems which useelectricity,electronics, andelectromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century aftercommercializationof theelectric telegraph, the telephone, andelectrical powergeneration, distribution, and use.
Electrical engineering is now divided into a wide range of different fields, includingcomputer engineering,systems engineering,power engineering, telecommunications,radio-frequency engineering,signal processing,instrumentation,photovoltaic cells,electronics, andopticsandphotonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering,power electronics, electromagnetics and waves,microwave engineering,nanotechnology,electrochemistry, renewable energies, mechatronics/control, and electrical materials science.[a]
Electrical engineers typically hold adegreein electrical engineering or electronic engineering. Practising engineers may haveprofessional certificationand be members of aprofessional bodyor an international standards organization. These include theInternational Electrotechnical Commission(IEC), theInstitute of Electrical and Electronics Engineers(IEEE) and theInstitution of Engineering and Technology(IET)(formerly the IEE).
Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range fromcircuit theoryto the management skills of aproject manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simplevoltmeterto sophisticated design and manufacturing software.
Dereham (/ˈdɪərəm/), also known as East Dereham, is a town and civil parish in the Breckland District of the English county of Norfolk. It is situated on the A47 road, about 15 miles (25 km) west of the city of Norwich and 25 miles (40 km) east of King's Lynn.
The civil parish has an area of 21.51 km2 (8.31 sq mi) and, in the 2001 census, had a population of 15,659 in 6,941 households; the population at the 2011 census increased to 18,609. Dereham falls within, and is the centre of administration for, Breckland District Council. The town should not be confused with the Norfolk village of West Dereham, which lies about 25 miles (40 km) away.
Since 1983, Dereham has been twinned with the town of Rüthen in North Rhine-Westphalia, Germany. It is also twinned with Caudebec-lès-Elbeuf, France. In spite of the reunification of Germany in 1990, the sign on the A47 at the entrance to Dereham from the Swaffham direction still refers to Rüthen being in West Germany; this sparks periodic comment in the local press.
