In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...
[2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system. [3]: 2 The Westinghouse air brake system is used world-wide; [3]: 93 in Europe two systems that use the same principle are the Kunze-Knorr and Oerlikon systems. It can be a single-stage ...

The joint does not allow translation, or sliding linear motion, a constraint not shown in the diagram. Almost all assemblies of multiple moving bodies include revolute joints in their designs. Revolute joints are used in numerous applications such as door hinges, mechanisms, and other uni-axial rotation devices. [2]
Example: A surface with a luminance of say 100 cd/m 2 (= 100 nits, typical PC monitor) will, if it is a perfect Lambert emitter, have a luminous emittance of 100π lm/m 2. If its area is 0.1 m 2 (~19" monitor) then the total light emitted, or luminous flux, would thus be 31.4 lm.
Similarly, a parallel set of instructions will perform a logical OR. In an electromechanical relay wiring diagram, a group of contacts controlling one coil is called a "rung" of a "ladder diagram", and this concept is also used to describe PLC logic. Some models of PLC limit the number of series and parallel instructions in one "rung" of logic.
In South Africa, the local GM subsidiary built the Viva two-door and four-door saloons as the Chevrolet Firenza from January 1971. A 1159 cc Vauxhall engine or a 2.5-litre Chevrolet inline-four, both locally made, were fitted. Two- or four-door saloons, a two-door coupé (2.5 only) and a three-door estate were available from the beginning.
