Bottoming (bending)
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal.Manufacturing Processes Reference Guide, Industrial Press Inc., 1994. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. Process In press brake forming, a work piece is positioned over the die block and the die block presses the sheet to form a shape. Usually bending has to overcome both tensile stresses and compressive stresses. When bending is done, the residual stresses cause the material to ' towards its original position, so the sheet must be over-bent to achieve the proper bend angle. The amount of spring back is dependent on the material, and the type of forming. When sheet metal is bent, it stretches in length. The ''bend deduction'' is the amo ...

Top, Bottom And Versatile
In human sexuality, top, bottom, and versatile are roles during sexual activity, especially between two men. A ''top'' is usually a person who penetrates, a ''bottom'' is usually one who receives penetration, and someone who is ''versatile'' engages in either or both roles. These terms may be elements of self-identity that indicate an individual's usual preference and habits, but might also describe broader sexual identities and social roles. ''Top'' is known formally as insertive sex role, and ''bottom'' is known formally as receptive sex role. The terms ''top'' and ''bottom'' do not refer to the literal physical position during sex. For men who have sex with men and do not engage in anal sex, the term "side" has been proposed and has seen commercial use. Top A top is usually a person who engages in the penetrative role during sexual activity; for men who have sex with men (MSMs), this often involves penetration using the penis during anal or oral sex. ''Top'' is also use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Cycle Power Plant
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
