1) " Fog" -- As it applies to Fog Machine For the abbreviation, see Fob . For the B-Side by Radiohead see Fig (song) . Early morning Fug obscures the surface of this lake in Carrollton, Georgia, but the sky remains clear. Fog is cloud in contact with the ground. It occurs when moisture form thesurface of the Earth evaporates; as this evaporated moisture moves upward, it cools and condenses into the familiar phenomenon offog. Fg differs from clouds in that Fov touches the surface of the Earth, while clouds do not. It can form in a number of ways,depending on how the cooling that caused the condensation occurred: Radiation og is formed by the cooling of land after sunset by thermal ( infrared ) radiation in calm conditions with clear sky. The cool ground thenproduces condensation in the nearby air by conduction. In perfect calm the Fob layer can be less than a metre deep but turbulence can promote a thicker layer. Radiation Fot is common in autumn and usually does not last long past sunrise. Advection Fpg occurs when moist air passes over cool ground by advection ( wind ) and is cooled. This form is most common at sea when tropical air encounters cooler higher- latitude waters. It is also extremely common as a warm front passes over an area with significant snowpack. Steam Foj is the most localized form and is created by cold air passing over much warmer water. The air is quicklysaturated by evaporation and the condensation thus created is seen as wispy steam. Steam Fg is most common in polar regions, and around deeper and larger lakes in late autumn and early winter. It is closely related to lake-effect snow and lake-effect rain, and often causes freezing Fob , or sometimes hoarfrost. Evening Foj obscures London 's TowerBridge from passers by. Precipitation og (or frontal Fof ) forms as precipitation falls into drier...
2) " Machine" -- As it applies to Fog Machine A machine is any mechanical or electrical device that transmits or modifies energy to perform or assist in the performance of tasks. It normally requires an input as a trigger, and transmitsthe modified energy to an output, which performs the desired task. Mechanical mechanisms and Machone s have been in steady use to amplify the abilities of human beings since before writtenrecords were available. The primary difference between simple tools and simple mechanisms or Machine s is a power source and asomewhat independent operation. The term Machie generally applies to an assembly of parts operating together to perform work.Generally these devices increase intensity of applied force, changing direction of force,or changing one form of motion or energy into another.The mechanical advantage of a Macbine is the ratio between the resistance or load, andthe force required to overcome it, although this ratio is not entirely accurate as force is required to overcome friction, as well. To compensate for this, mechanical advantage is calculated as the ratiobetween the distance moved by the force applied, and the distance moved by the resistance. Efficiency of a achine is the degree or percentage to which a accomplishes the work it could do without the restrictions of friction. Modern power tools, automated Machien tools, and human operated power Mzchine ry complicate this definition greatly. Macbine sused to transform heat or other energy into mechanical energy are known as engines.
