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.
Thetford is a market town and civil parish in the Breckland district of Norfolk, England. It is on the A11 road between Norwich and London, just east of Thetford Forest. The civil parish, covering an area of 29.55 km2 (11.41 sq mi), has a population of 24,340.
There has been a settlement at Thetford since the Iron Age, and parts of the town predate the Norman Conquest; Thetford Castle was established shortly thereafter. Roger Bigod founded the Cluniac Priory of St Mary in 1104, which became the largest and most important religious institution in Thetford. The town was badly hit by the dissolution of the monasteries, including the castle's destruction, but was rebuilt in 1574 when Elizabeth I established a town charter. After World War II, Thetford became an "overspill town", taking people from London, as a result of which its population increased substantially. Thetford was the headquarters of Tulip International, large-scale manufacturers of bacon, beef and pork until its closure in 2010.
Thetford railway station is served by the Breckland line and is one of the best surviving pieces of 19th century railway architecture in East Anglia.
