Nash Equilibrium is a term used in game theory to describe an equilibrium where each player's strategy is optimal given the strategies of all other players.
Retaining rings are circular fasteners that fit over shafts or inside cylindrical products such as pipe. There are two main types: internal and external. Internal retaining rings have a diameter specified for the bore and groove sizes they will fit into. External retaining rings, also known as retaining rings for shafts, have a diameter specified for the shaft and groove sizes it fits around. Both industrial retaining ring types, also known as a retaining clip, have a thickness dimension. Measurements will be expressed in inch or millimeters. Retaining ring material varies based on application. Stainless steel retaining rings are made from one of the most common ring materials.
Viton is generally compatible with hydrocarbons, but incompatible with ketones such as acetone, and organic acids such as acetic acid. O-rings made of Viton are typically color-coded as black, but new gaskets, seals and O-rings should be green FKM or black FKM, but with a green mark on the outer edge.here are four families of viton polymers: 1  A (Dipolymers of VF2/HFP): General purpose sealing. 2  Automotive, Aerospace fuels & lubricants. 3  Nominal polymer fluorine content: 66%. 4  B (Terpolymers of VF2/HFP/TFE): Chemical Process plant, Power Utility Seals & Gaskets.
