Collectivism. Collectivism means the subjugation of the individual to a groupâwhether to a race, class or state does not matter. Collectivism holds that man must be chained to collective action and collective thought for the sake of what is called âthe common good.â.ollectivism holds that, in human affairs, the collectiveâsociety, the community, the nation, the proletariat, the race, etc.âis the unit of reality and the standard of value. On this view, the individual has reality only as part of the group, and value only insofar as he serves it.
Oil viscosity. Absolute viscosity provides a measure of a fluidâs internal resistance to flow. For liquids, viscosity corresponds to the informal notion of thickness. For example, honey has a higher viscosity than water. Any calculation involving the movement of fluids requires a value of viscosity.
Viscosity (a fluid's resistance to flow) is rated at 0Â° F (represented by the number preceding the W [for Winter]) and at 212Â° F (represented by the second number in the viscosity designation). So 10W-30 oil has less viscosity when cold and hot than does 20W-50. Motor oil thins as it heats and thickens as it cools.So, with the right additives to help it resist thinning too much, an oil can be rated for one viscosity when cold, another when hot.or example, oil tends to lose viscosity from shear, the sliding motion between close-fitted metal surfaces of moving parts such as bearings. So resistance to viscosity loss (shear stability) is necessary to enable the oil to maintain the lubricating film between those parts.
