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.
20W-50. A 20W-50 oil is a heavier multi-viscosity oil appropriate for higher temperatures and higher loads, which require a more viscous oil. The minimum temperature this oil will pour at is 20 degrees Celsius, and its viscosity rating at 100 degrees Celsius is 50. 5W-30 oil is commonly used in passenger cars for normal use throughout the year. A 20W-50 oil will not protect a car as well in a cold winter and its greater viscosity will increase drag and friction in a passenger vehicle.
