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…

The following are the critical dimensions and geometries concerned with toothed gear: Pitch Circle : A pitch circle is an apparent circle in which two gears can be taken like smooth cylinders rolling without friction. Addendum Circle : The addendum circle is the …

Water hand pumps are manually operated pumps. They are used to bring water from the earth's underground to the earth's surface and are used in every country for various industrial, marine, irrigation, and household purposes. The image shown below is the typical…
