Lagrange-d’Alembert principle is generally known as D’Alembert’s principle, stated by French physicist and mathematician polymath Jean le Rond d’Alembert. According to d’Alembert’s principle, the external forces acting on a body and the resultant inertia forces on a…

Pipes are circular in cross-section, identical to the shape of a roll of paper towels. We typically use pipes in our homes to distribute water from the water tank to various areas, such as the kitchen and bathroom. Three different types of fluid flow are written in br…

Selecting the factor of safety to be used for various applications is one of the most critical engineering tasks. On the one hand, if a factor of safety is chosen too small, the possibility of failure becomes unacceptably large; on the other hand, if a factor of safety…

General characteristics of different forming and shaping processes such as flat rolling, shape rolling, drawing, extrusion, forging, forming and shaping of ceramics, sheet-metal forming, powder metallurgy and processing of plastics & composite materials . S.no…

Brittle fracture is a significant concern in Industrial Damage Mechanism and is characterized by a sudden fracture in the material under stress. Typically, all construction materials are susceptible to damage and efforts have been made to prevent failures in equipment …

Hydraulic turbines are Machines that convert hydraulic energy into mechanical energy. The mechanical energy runs an electric generator directly coupled to the turbine's shaft. The generator generates electric power, sometimes known as hydroelectric power. Generall…

A key is a machine element fitted in an axial direction into the mating member, such as pulleys, gears. The key's primary function is to prevent the relative rotation between the shaft and mating member. In most applications, the keys' secondary function is to…
