Piston velocity is a test of the strength of the piston and connecting rod subassembly. FMEAs can be performed at the system, subsystem, assembly, subassembly or part level. This classification is overlapping, because a subassembly could be a part in another assembly configuration. NASA uses system, segment, element, subsystem, assembly, subassembly, and part (NASA, 1995). Also testing of the androgynous peripheral docking subassembly of the Kristall module was performed. A barnacle may also be a complex subassembly or daughterboard. Each subassembly contained 36 fuel rods in a Zircaloy-2 channel. For example, a subassembly of three triangle corners forms a triangle, the most stable configuration. When an error occurs at a part or subassembly, it needs to be revised. Later on, the car was restyled by Pinin Farina and subassembly began in Italy. B-29A-BN used a different subassembly process and was a foot longer in span. A subassembly plant was located in Fargo, ND.
