Mechanics
Mechanics (from Ancient Greek: μηχανική, ''mēkhanikḗ'', "of machines") is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. Theoretical expositions of this branch of physics has its origins in Ancient Greece, for instance, in the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, Huygens, and Newton laid the foundation for what is now known as classical mechanics. As a branch of classical physics, mechanics deals with bodies that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as the physical science that deals with the motion of and forces on bodies not in the quantum rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-doctoral
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regional Engineering College, Srinagar
In geography, regions, otherwise referred to as zones, lands or territories, are areas that are broadly divided by physical characteristics (physical geography), human impact characteristics (human geography), and the interaction of humanity and the environment (environmental geography). Geographic regions and sub-regions are mostly described by their imprecisely defined, and sometimes transitory boundaries, except in human geography, where Jurisdiction (area), jurisdiction areas such as national borders are defined in law. Apart from the Earth, global continental regions, there are also hydrosphere, hydrospheric and atmosphere, atmospheric regions that cover the oceans, and discrete climates above the land mass, land and water mass, water masses of the planet. The land and water global regions are divided into subregions geographically bounded by large geological features that influence large-scale ecologies, such as plains and features. As a way of describing spatial areas, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jammu University
Jammu is the winter capital of the Indian union territory of Jammu and Kashmir. It is the headquarters and the largest city in Jammu district of the union territory. Lying on the banks of the river Tawi, the city of Jammu, with an area of , is surrounded by the Himalayas in the north and the northern-plains in the south. Jammu is the second most populous city of the union territory. Three battles have been fought in the city: first by the founder Raja Mal Dev against Timur in Battle of Jammu (1399), second by Sardar Bhag Singh against Mughal army in Battle of Jammu (1712) and the third by Mian Dido & Maharaja Gulab Singh against Ranjit Singh's army in Battle of Jammu (1808). Known as the ''City of Temples'' for its ancient temples and Hindu shrines, Jammu is the most visited place in the union territory. Jammu city shares its borders with the neighbouring Samba district.

History Of Civilization (1967)
Human history, also called world history, is the narrative of humanity's past. It is understood and studied through anthropology, archaeology, genetics, and linguistics. Since the invention of writing, human history has been studied through primary and secondary source documents. Humanity's written history was preceded by its prehistory, beginning with the Paleolithic ("Old Stone Age") era. This was followed by the Neolithic ("New Stone Age") era, which saw the Agricultural Revolution begin in the Middle East around 10,000 BCE. During this period, humans began the systematic husbandry of plants and animals. As agriculture advanced, most humans transitioned from a nomadic to a settled lifestyle as farmers in permanent settlements. The relative security and increased productivity provided by farming allowed communities to expand into increasingly larger units, fostered by advances in transportation. The earliest complex societies appeared in fertile river ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal Forming
Forming, metal forming, is the metalworking process of fashioning metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is permanently deformed. Characteristics Metal forming tends to have more uniform characteristics across its subprocesses than its contemporary processes, cutting and joining. On the industrial scale, forming is characterized by: * Very high loads and stresses required, between 50 and () * Large, heavy, and expensive machinery in order to accommodate such high stresses and loads * Production runs with many parts, to maximize the economy of production and compensate for the expense of the machine tools Forming processes Forming processes tend to be categorised by differences in effective stresses. These categories and descriptions are highly simplifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicles
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles ( trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles ( screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions. History * The oldest boats found by archaeological excavation are logboats, with the oldest logboat found, the Pesse canoe found in a bog in the Netherlands, being carbon dated to ...

Crashworthiness
Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of aircraft and vehicles. Depending on the nature of the impact and the vehicle involved, different criteria are used to determine the crashworthiness of the structure. Crashworthiness may be assessed either prospectively, using computer models (e.g., LS-DYNA, PAM-CRASH, MSC Dytran, MADYMO) or experiments, or retrospectively by analyzing crash outcomes. Several criteria are used to assess crashworthiness prospectively, including the deformation patterns of the vehicle structure, the acceleration experienced by the vehicle during an impact, and the probability of injury predicted by human body models. Injury probability is defined using criteria, which are mechanical parameters (e.g., force, acceleration, or deformation) that correlate with injury risk. A common injury criterion is the head impact criterion (HIC). Crashworthiness is as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constitutive Equation
In physics and engineering, a constitutive equation or constitutive relation is a relation between two physical quantities (especially kinetic quantities as related to kinematic quantities) that is specific to a material or substance, and approximates the response of that material to external stimuli, usually as applied fields or forces. They are combined with other equations governing physical laws to solve physical problems; for example in fluid mechanics the flow of a fluid in a pipe, in solid state physics the response of a crystal to an electric field, or in structural analysis, the connection between applied stresses or loads to strains or deformations. Some constitutive equations are simply phenomenological; others are derived from first principles. A common approximate constitutive equation frequently is expressed as a simple proportionality using a parameter taken to be a property of the material, such as electrical conductivity or a spring constant.
